Getting Ugly
For the past few weeks, I've been slowly walking through
the strategy table for full-pay jacks or better video poker. I'm about 2/3 of the way though and what's
left is well, just not pretty. The
expected values of the rest of the table are below 0.60. This means you can expect, on average, a
return of only 60% of your wager. But,
as I've explained the past few weeks, learning to play the ugly hands is at
least as important as learning how to play the good hands. It is also probably more difficult to learn these
hands as there are a lot of subtle nuances and a great deal of overlap. For example, one of the hands from last week
was the 2-Card Royal with no Aces or 10's.
This week's top hand is a 4-Card Inside Straight with 4 High Cards,
which is really a 4 High Card hand.
There is only one way this occurs -
J Q K A. But, if we compare this
to the 2-Card Royal we realize that if TWO of the J/Q/K are suited, we actually
go that route instead of the 4-Card Inside Straight.
Let's take a look at the next few entries and see what we
can learn from them:
· 4-Card Inside Straight with 4 High Cards
· 2-Card Royal with an Ace, but no 10
· 3-Card Double Inside Straight Flush with 1 High Card
· 4-Card Inside Straight with 3 High Cards
· 3-Card Inside Straight Flush with 0 High Cards
· 3 High Cards
Okay, so we've already covered a critical point of these
hands above. Adding to the complexity
however is the 2nd rule down when compared with the 1st. IF the 2 suited cards are an Ace and either
the Jack, Queen or King, THEN we keep the 4-Card Straight!
Next up is the 3-Card Double Inside Straight Flush with 1
High Card. So, a suited 8-9-Q would
cover this. This can't overlap with our
2-Card Royals, but can overlap with a 4-Card Inside Straight (8-9-Q suited with
a Jack off-suit). This would make it a
4-Card Inside Straight with 2 High Cards.
You'll note that the 4-Card Inside Straight with 3 High Cards is below
the 3-Card Double Inside Straight with 1 High Card, so surely the 2 High Card
version is even lower. In reality, we
won't find it on this strategy table at all as a 4-Card Inside Straight with 2
or less High Cards is NOT a playable hand in full-pay jacks or better. In this case we would keep the 3-Card
Straight Flush over the 4-Card Straight.
The next hand is the 3-Card Inside Straight Flush with 0
High Cards (i.e. 5-7-8 suited). If we
have a 6 off-suit this would be a 4-Card Straight with 0 High Cards which is
much higher in the table and thus would be played as the 4-Card Straight. If we have a 4 off-suit, then it is a 4-Card
Inside Straight with 0 High Cards. If
the 2 High Card version is not playable then for sure neither is the 0 High
Card Version. We would play the 3-Card
Straight Flush.
The 3 High Card hand is a critical hand to learn
about. It is frequently misplayed. There are four possible High Cards - Jack,
Queen, King and Ace. However, 3 High
Cards is a bit of a misnomer. In order
for the hand to be 3 High Cards, it MUST be J-Q-K. If we have J-Q-A we would discard the Ace
unless the Ace matches in suit to one of the other two then it would play as a
2-Card Royal. In similar fashion, we
would ONLY play J-Q-K if the three are of different suits. Otherwise we would again have a 2-Card Royal
(V3) and would play the hand that way.
The 2-Card Royals are frequently overlooked when there is a 3rd High
Card, but this is simply not the right way to play the hand.
There are only 5 more hands on our strategy table and I
will cover them next week. These five hands all have expected value below
0.50. Unfortunately, they account for
about 1/3 of all hands dealt - so they are critical to learn.

Distinguished Royals
I've spent the past few weeks walking through the
strategy table for full-pay jacks or better video poker. This week, we are in the heart of the table,
which is to say we are in the middle of the really bad hands. But, bad hands are the harder hands to play
correctly and are just as important as the good hands in achieving the
theoretical strategy of any particular game.
We finished up last week with the 4-Card Straights. From here the hands only get uglier. The next several entries are:
· 3-Card Double Inside Straight Flush with 2 High Cards
· 3-Card Inside Straight Flush with 1 High Card
· 3-Card Straight Flush with 0 High Cards
· 2-Card Royal Flush - "V3"
If you're relatively new to strategy tables, this part of
the table has problem just given you a doozy of a headache! The good news is that it is not nearly as
confusing as it might appear. Many of
the hands listed above cannot co-exist - meaning that you can't have more than
one in a particular hand. Thus, remembering
the exact order may not be as important as it might appear to be. For example, you can't have a 3-Card Double
Inside Straight Flush with 2 High Cards in the same hand as a 3-Card Straight
with 0 High Cards. You'd either have to
have at least 4 cards of one suit or have 2 sets of 3-Cards of different suits
- rather difficult with 5 cards.
There are still important things we can learn from this
section of the table. We separate the
hands the way we do because in some games the impact of the subtle differences
and the order of the hands will be different and thus become pertinent. The first thing you might notice is the
relationship of the top three hands. We
get a sense of the importance of a High Card.
A 3-Card Double Inside Straight Flush with 2 High Cards has a higher
expected value than a 3-Card Inside Straight Flush with only 1 High Card. Essentially, the value of the extra High Card
is greater than the value of the additional Straight Flushes (and Straights)
that may occur as a result of having an Open vs. Inside vs. Double Inside
Straight Flush. What this should also
tell us is that you shouldn't hold your breath for those Straight Flushes. They will occur, but not often. At the same time, I have written at length
over the years about how the Straight Flush is the forgotten hand of video
poker. Playing 3-Card Straight Flushes
correctly is very important to drawing them in proper abundance. While their pays are far short of the Royal,
they still pay double what Quads pays so their value should not be dismissed.
Next up is the 2-Card Royal Flush - "V3". 2-Card Royals are given 4 different
designation from "V0" to "V3". We
need to do this because the expected values of many of the hands in this part
of the table differ by only 0.01 or 0.02.
As not all 2-Card Royals have identical expected values, we need to
distinguish between them. V3 means that
the 2-Card Royal contains neither a 10 nor an Ace. An Ace in a 2-Card Royal essentially makes it
a Double Inside Royal. All 2-Card Royals
have the same number of ways to make a Royal - one. But, with the Ace, we eliminate all ways to
make a Straight Flush. While a '10'
doesn't have this problem, it does have the problem that it is not a High
Card. So, Aces are worth less than
Jacks, Queens and Kings and 10's are worth less than Aces. Thus, a 2-Card Royal with neither an Ace nor
a '10' is the one with the highest expected value. A V2 2-Card Royal means that the 2-Card Royal
has an Ace, but no 10. A V1 2-Card Royal
is one that has no Ace, but does have a 10.
Lastly, a V0 2-Card Royal consists of a 10 AND an Ace.
For the moment, I'll jump to below the strategy table -
to the V0 2-Card Royal. We are 'below'
the strategy table because this hand does not exist on the strategy table for full-pay
jacks or better. This means that we DO
NOT PLAY an A-10 2-Card Royal. Barring
the other three cards forming an otherwise playable hand, we would simply hold
the single Ace. More on that in a couple
of weeks.
The proper play of 2-Card Royals is critical to learning
how to master video poker strategy.
Unlike the prior 3 hands, 2-Card Royals overlap with EVERYTHING. You'll have 2-Card Royals with High Pairs,
Low Pairs, 4-Card Straights, 4-Card Flushes, 3-Card Straight Flushes, 3-Card
Inside Straight Flushes, etc... If you
blindly go after every 2-Card Royal, you'll hit more than your fair share of
Royals, but you'll lower the payback of your play. If you ignore 2-Card Royals, you'll miss you
fair share of Royals AND lower the payback of your play. The only answer is to play them when you are
supposed to. Based on the portion of the
strategy table shown, you can easily have a 3-Card Double Inside Straight Flush
with 2-High Cards AND a 2-Card Royal - V3.
For example, you could have 8-J-Q suited. From the strategy table, we learn that we
keep the 8 in this case. You might also
have a 3-card Straight Flush completely apart from a 2-card Royal. For example, 3H, 4H, 5H, JD, QD. In this case, we discard the 2-Card Royal in
favor of the 3-Card Straight Flush with 0 High Cards.
I've now covered about 2/3 of the strategy table for
jacks or better video poker. Next week,
we continue through the rest of the messy hands.

Stroll Through the Strategy Table
This week we continue our walk through a video poker
strategy table. Specifically, the
strategy table for full-pay jacks or better video poker. Last week we left off at the 4-Card Flush
which was the last of the hands with an expected value of greater than
1.0. These are the hands that result in
net wins in the long run. The rest of
the strategy table have expected values below 1.0. This means that in the long run we will not
get back our entire wager. But, that
doesn't make them any less important.
When playing video poker, playing every hand correctly is critical if
you want to achieve the theoretical payback.
It could be argued that playing the hands below 1.0
correctly is more important than playing the ones above this line
correctly. First, the hands below make
up the lion's share of hands. Second,
the hands below are by far more complex than the ones above. You don't have to worry about confusing a
Two-Pair with a 4-Card Straight Flush as this is an impossibility. But a 4-Card Straight vs. a 3-Card Straight
Flush might leave you shaking your head.
Without further ado, here are the next batch of hands on
our strategy table:
· 4-Card Straight with 3 High Cards
· Low Pair
· 4-Card Straight with 2 High Cards
· 4-Card Straight with 1 High Card
· 3-Card Inside Straight Flush with 2 High Cards
· 3-Card Straight Flush with 1 High Card
· 4-Card Straight with 0 High Cards
The first thing you'll probably notice is that with the
exception of the Low Pair, the number of High Cards is specified. When the inventor of video poker decided to
pay on Jacks or better, he added an incredible layer of complexity to the
strategy. Simply put, in any hand
without a Pair or better, any card that is a Jack or higher is worth
considerably more than any other card. The
reason should be fairly obvious. We have
the opportunity to win with High Pairs.
For each High Card in the hand, we have three additional cards that we
can draw that will turn our hand into a winner.
These three cards add just over 0.06 to the expected value of the
hand.
Sometimes, this 0.06 means nothing and sometimes it means
everything. We just need to look at the
first three hands to see the impact. If
you have a 4-Card Straight with 3 High Cards and a Low Pair, you keep the
partial Straight. If you have a 4-Card
Straight with 2 High Cards and a Low Pair, you keep the Lower Pair. These hands are not very common, but they
illustrate the impact of the High Card.
So, if you have 10-10-J-Q-K (assuming no 3-Card Royal), then you keep
the Straight. If you have 9-10-10-J-Q
then you keep the Low Pair. Having a 9
instead of a King lowers the expected value so that it falls just below that of
the Low Pair.
If we keep moving down the chart, we find that the next
entry is the 4-Card Straight with 1 High Card.
As this is adjacent to the 2 High Card version, there really is no
impact in this case. We could lump these
two hands together if we want to remove 1 hand from the strategy table. We keep them separate because there are
versions of video poker where it is relevant and we want to make sure the
Player doesn't get 'lazy'.
In between a 4-Card Straight with 1 High Card and a
4-Card Straight with 0 High Cards we find 2 other hands. They are both variants of a 3-Card Straight
Flush. The first is an Inside Straight
Flush with 2 High Cards and the second is a 3-Card Straight Flush with 1 High
Card. This can start looking more
confusing than it really is. Most of
these hands CANNOT occur in a single hand.
It is not possible to have both a 3-Card Straight Flush with 1 High Card
and a 3-Card Inside Straight Flush with 2 High Cards. But, you can have a 4-Card Straight with 1
High Card with a 3-Card Straight Flush with 1 High Card. (8C 9D 10D JD 4H). We learn from the strategy table that the right
play is the 4-Card Straight.
One last point that I should mention. All the 4-Card Straights to this point have
been Open Straight Flushes - meaning that they can be completed on both
ends. This means that as we have
completed about 60% of the strategy table, we have accounted for all Pairs and
for all 4-Card Straights (Open ended) and 4-Card Flushes. The remaining 40% of the strategy tables
contains very 'not pretty' hands. It is
a mish-mosh of 3-Card Straight Flushes, Inside Straight Flushes and even Double
Inside Straight Flushes, along with 2-Card Royals and hands with just High
Cards. To make matters worse, these 40%
of the entries account for nearly 50% of the hands.
Next week, we'll continue our stroll through the strategy
table.

Get the Inside Scoop
Last week I began reviewing the strategy table for
full-pay jacks or better video poker. I
got about 20% of the way through the table by volume, but not very far in terms
of useful information. The top 8 hands were
mostly of the no-brainer category as they were the pat hands with the exception
of the 4-Card Royal. This week, I'll
keep moving down the table and provide some insight into the nuances of video
poker strategy. Please remember that
this particular strategy is applicable ONLY to full-pay jacks or better.
After a Straight, we find the following entries on our
table:
· 4-Card Straight Flush
· Two Pair
· 4-Card Inside Straight Flush
· High Pair
· 3-Card Royal Flush
· 4-Card Flush
The first thing you might notice about the above entries
is that we have two entries for a 4-Card Straight Flush and a 4-Card Inside
Straight Flush. There is a big
difference between the expected values for Straights that are open and those
that are Inside (or Double Inside). The
common definition of Inside Straight is when the opening is in the middle and
not on the ends (i.e. 5-6-7-9). However,
this leaves off some Inside Straights.
It is more accurate to define a 4-Card
Inside Straight as one that can only be filled ONE WAY. So, an A-2-3-4 can only be filled with a 5
and thus is an Inside Straight. With
this definition you can see that an Inside Straight can be completed with only
4 cards while a regular Straight can be completed with 8 cards. Straight Flushes are no different - except
they have the possibility of being turned into Flushes as well.
In this particular case, there is really no benefit to
splitting out the 4-Card Straight Flushes.
The one hand that lies between them can't possibly be a 4-Card Straight
Flush (Inside or not). We show them
separately because in some version of video poker, the hands that appear in
between may be able to overlap with them and we will find that in some cases we
will want to keep a 4-Card Straight Flush ONLY if it is not an Inside Straight
Flush. Also, as we will see as we move
down the table, this distinction becomes very important as we take a closer
look at 4-Card Straights.
The 4th entry on the table is a critical one - High
Pair. It is the 4th most common
hand. Thus, playing it correctly is very
important. Looking at the entries above
it and below it what we learn is that a High Pair is played OVER any 4-Card
Straights and 4-Card Flushes. We will,
however, play all 4-Card Straight Flushes over a High Pair. But, we will NOT play a 3-Card Royal over the
High Pair. So, if you have a suited
J-Q-K along with another Queen, you stick with the sure winner - the Pair of
Queens.
Below High Pair, we have a 3-Card Royal Flush and a
4-Card Flush. There is much to learn
here as well. The most obvious is that
if you have a 3-Card Royal and a 4-Card Flush, we hold the 3-Card Royal. This can be a tough choice because the
likelihood of hitting the Royal is still relatively small. But, by holding a 3-Card Royal we give
ourselves more chances for a Straight.
We might still hit a Flush and we have the longshot at the Royal. Also, with a 3-Card Royal, we leave ourselves
2-3 cards that can be matched up for a High Pair. The expected values are not really all that
close with a 1.41 for the 3-Card Royal and 1.22 for the 4-Card Flush. The decision is relatively clear.
From these entries we also learn that if the Player has a
3-Card Royal that is also a 4-Card Straight Flush (8-10-J-Q), we hold the
4-Card Straight Flush. With the 4-Card
Straight Flush, we still have many chances for Straights and Flushes so we
don't throw away the extra card even if it gives us a chance to get the Royal.
I've stopped at this particular point in the Strategy
Table because the 14 hands I've listed (over the past 2 weeks) are the only
ones with an expected value greater than 1.0.
That means these hands are net winners in the long run. Some will be winners 100% of the time. Some will not. But in the long run, we can expect to get
more back than we wagered. These hands
make up about 40% of the table and about 25% of the total hands dealt. Beginning next week, we'll review the hands
with an expected value below 1.0. Even
though these are losers in the long run, it doesn't make them less
important. In fact, they may be more
important because they account for a larger percentage of hands dealt.

Strategize
Every casino game that is more than pure luck has some
strategy associated with it. This goes
beyond the basic strategy that simply says you're better off not playing at
all. For many games, the strategy can be
summed up with a simple sentence or two.
For Three Card Poker, it is Play Q-6-4 or better. Four Card Poker has a two sentence strategy
that tells you when to fold and when to Raise.
Let It Ride's strategy takes a few sentences telling you when to pull
down the 1 and 2 wagers.
As strategy gets more complex, it is helpful to try and
put it into as easy as a format as possible to help a mere mortal to utilize
it. It is relatively easy to program a
computer to play a game perfectly. Very
few humans can take every game to this level.
Also, expending that much energy on memorizing a very complex strategy
can pretty much sap the fun right out of the game. Blackjack utilizes a relatively simple matrix
that crosses the Player's hand with the Dealer's upcard.
Creating a strategy for video poker is quite a
challenge. As said earlier, telling a
computer which one of the 32 ways to play a hand is relatively easy. But, there are 2,598,960 unique 5-card deals
from a standard deck. Coming up with a
way to group these together in a way that a Player can use is a whole different
story. I believe it was my father, Lenny
Frome, who was the first person who accomplished this. He grouped hands together in a way that
Players could easily understand and hopefully memorize.
A video poker strategy table consists of only two
columns. The first contains the hand
rank as it was categorized by my father.
The second contains the expected value of the hand. Ironically, this second column isn't even
needed to play video poker properly. It
is there just for reference. So, that
means the video poker strategy table consists of a single column - usually with
about 30-40 rows/entries in it. To play
video poker the correct way, you have to memorize the order of these
entries. This is not nearly as daunting
as it seems. About 10-15 of these
entries are more than a little obvious.
So, you're left with about 25 hand types that you need to learn.
Let's start at the top of the strategy table which
contain the most obvious hands:
· Royal Flush
· Straight Flush
· Four of a Kind
· 4- Card Royal
· Full House
· Flush
· Three of a Kind
· Straight
We'd be having a great night at video poker if these were
the only hands we were dealt. These are
all big winners, all with expected values of 4.00 or better. In fact, only one of these hands is not a
sure winner - the 4-Card Royal. This is
also the only hand that might overlap with any of the others, creating the only
strategy decision in the bunch. What do
you do if you are dealt a Straight (or a Flush) that is also a 4-card
Royal? Well, now you know the
answer. You have to throw away the sure
winner to go for the big winner. The
good news is that if you have a 4-Card Royal, you have a very good chance of
still winding up a winner. There are 47
possible draws, 1 of which will result in the Royal. Another will give you a Straight Flush. 6 or 7 more (depending on whether you threw
away a Straight or Flush) will result in a Flush. 5 or 6 will result in a Straight and a host
more will give you at least a High Pair which will seem like small consolation.
While this decision might be agonizing, mathematically,
it is very clearly the proper play. The
expected value of the 4-Card Royal is 18.66.
The expected value of the Flush is 6 and the Straight is 4. Of course, don't expect to see this hand
every hour. A 4-Card Royal will show up
once in about 2700 hands and only about a third of these will be a Straight or
a Flush. One other key point to
note. Do NOT throw away a Straight Flush
to go for the Royal. That Straight Flush
has an expected value of 50 which far exceeds the 18+ of the 4-Card Royal.
Next week, I'll move down the strategy table to the hands
that require a bit more thought.

Table your Hunches
Last week, I described how all casino game strategy is
based on expected values. You hit or
stick in blackjack not because you hope the next card is of a certain value,
but because there are certain probabilities as to what the next card will be
and how it will affect your hand and your chances of winning or losing. If
you're dealt two face cards, you don't give much thought to strategy. Hopefully, you're not one of those Players
who even thinks about splitting 10's!
But, if you are dealt a 16 and the Dealer has a 7, you
start giving thought to the strategy.
With a 16, you have 5 cards that will help you and 8 that will bust
you. The odds don't look to good and
this is why a lot of people stick on this hand, albeit incorrectly. You can stay put, but with a 16, the only way
you can win is if the Dealer busts, which will happen only 26% of the
time. So, your choices are a 61% chance
of busting right away or sticking and having a 74% chance of losing that
way. Of course, by hitting you also have
an opportunity improve your hand. All of
the 5 possibilities improve your hand.
If you pick up an Ace, you'll be most likely to push. Pick up a 5 and you'll win more than 92% of
the time. Don't get me wrong, it is not
a strong hand and the decision to hit is not an overwhelming one, but it is
still the right move. In the simplest
form, if you face this situation enough times - which you will if you play for
a few hundred hours, you'll find that you do better by hitting than by
sticking.
In blackjack, you don't have to memorize all of the math
behind the game. You don't have to
figure out how many cards will bust you or bust the Dealer. To learn to play blackjack, many Players use
a simple strategy table. It is a simple
little chart that shows every possible Player hand and each possible dealer
upcard. It then shows what to do - hit,
stick, double, split, surrender, etc..
Guys like me have already done all the number crunching for you.
Video poker is no different than blackjack except the
decision making process is far more complex.
In blackjack, the result is essentially binary - you win or you lose
(okay, you can tie also, so it is not really binary). In video poker, you can have 1 of many
results - ranging from a Royal Flush down to a High Pair or you can lose. Since each of the different winning hands
pays a different amount, the specific result must be taken into account. If someone invented a game of video poker in
which all hands above a certain rank paid a fixed amount, then we'd be able to
lump all the hands into win or lose.
But, we need to know the probability of each final outcome with a
different payout in order to appropriately determine the value of getting that
hand. Surely, it is more valuable to
wind up with a Straight Flush than just a Straight.
Video poker is also more complex than blackjack in that
there is more than just a handful of different possibilities for each
hand. The Player can hold all 5 cards or
discard all 5 cards or anything in between for 32 different possible
plays. Yes, most of these possibilities
will be quickly discarded, but they still must be considered from a
mathematical perspective. They are only
discarded because the human mind can quickly recognize possible draws that
would clearly not be the best strategy.
Despite the extra complexity of video poker, the
similarities are still stronger than the differences. In the end the decision still comes down to
the expected value. Like in blackjack,
you don't have sit there trying to figure out how many cards you need to
complete a Straight or the like. Again,
guys like me have already done the job.
We have looked at every possible deal, every possible draw for every
possible deal and summed up all of the final hands. Using this distribution, each possible draw
is assigned an expected value. Whichever
draw has the highest expected value is deemed the right play. The last step in the process is too try and
categorize the way each hand is played into a format that a human can use to
play the hands. We call this a strategy
table.
Unlike blackjack where the strategy is a matrix that
crosses Player hands with Dealer hands and tells you what to do, a video poker
strategy chart lists all the possible playable hands in order in a simple
table. The table usually contains the
expected value of each hand too, but this is just for information. To use the strategy table, you basically work
from the top and find the first hand that your dealt hand can make and that is
the way to play the hand. So, if you are
dealt a hand that is a 4-Card Straight and a Low Pair, you start at the top of
the table and work downward. If a 4-Card
Straight appears first, you play that.
If a Low Pair appears first, you play the hand that way. If you can't find any hand that matches the
hand you were dealt, then you fall to the bottom of the table and find a RAZGU
which means throw all five cards.
Next week, we'll begin breaking down a strategy table for
full-pay jacks or better. You'll be on
your way to becoming an Expert Player.

The Advantage of Expert Play
This morning, I had a discussion with a friend of mine
about a game he is developing. I
explained that playing 'perfect' strategy would be nearly impossible due to
some subtle complexities of the way the game is played. As a result of this, the game would not
likely play anywhere near its 'theoretical' payback. Many games have this 'problem'. Blackjack pays 99.5%, but very few players
play anywhere near this. Ultimate Texas
Hold'em has a payback well into the 99% range too, but stats from the casinos
make it clear that very few Players, if any, can manage this high of a payback.
My friend stated that he thought that he would be able to
play the game close to the theoretical because he is an accomplished Poker
Player. I asked him if he was an
accomplished video poker Player and he said that he wasn't. I told him that any table game against a
Dealer was really nothing more than playing video poker and had no resemblance
to poker even if the game resembles poker. Poker is about reading Players, understanding
their betting patterns and their tells.
Video Poker is about one thing - math.
There is no one to bluff. All
that matters is what is the probability of all final hands given what I choose
to discard. Let's take a look at a
simple example:
5♠ 5♦ 6♣ 7♥ 8♦
In theory, there are 32 ways to play this hand, but I
think we can quickly rule out 29 of them.
I don't think anyone is seriously going to consider holding only the
off-suit 6-8 or holding all 5 cards (which would result in an immediate
loss). There are really on 3 possibilities, 2 of which are identical.
The Player can either hold the Pair of 5's or the 4-Card Straight
(hence, the 2 identical possibilities as it doesn't matter which 5 the Player
keeps.)
If the Player keeps the 4-Card Straight, 8 cards will
result in a Straight and the rest will result in a loss. So, if we add up the total payout, we'd have
8 Straights at 4 units each for a total of 32 units. There are 47 possible draws. We divide the 32 by 47 to get 0.68. This is called the Expected Value (or EV) of
this hand using this possible discard strategy.
Calculating the Expected Value of holding the Pair is a
bit more complex, but easy enough to calculate using a computer. There are 16,215 possible draws if the Player
holds 2 cards. We look at these possible
draws and look at the final hands. The
Player can wind up with a Four of a Kind, Full House, Three of a Kind or Two
Pair. We add up the total payout of all
of these winning hands and divide by 16,215.
The result is an EV of 0.82.
This Expected Value is greater than that of the 4-Card
Straight, so the proper play is to hold the Low Pair. When Playing video poker (and virtually every
other casino game), the proper play is to follow the one with the highest
EV. You don't go with a 'hunch' that a 5
is coming up or that you just feel a 4 or a 9 is going to fill out that
Straight. There is a distinct
probability of each of these events occurring and we use those probabilities to
our advantage. This is what allows a
Player go achieve the theoretical playback of a game.
It is an 'advantage' because most Players don't play this
way. Because of this, the casinos can
off the games with a relatively high payback, knowing that they can rely on
human error to pad their profits. For
the Players who play according to the math, they have the advantage of being
able to play to the theoretical payback over the long run.
Mastering video poker takes some significant effort. The strategy is a complex one and learning
whether to hold the Low Pair or the 4-Card Straight is merely one example of
where a strategy where you play by what you think is right may in fact be quite
wrong. The good news is that thanks to
guys like me, the toughest party of learning the strategy (creating it) has
already be done for you. The next step
is learning that strategy and putting it to practical use. We'll save more of that for next week.

Video Poker Primer
It was just over 10 years ago that I started writing for Gaming Today. I have to be honest, that really blows me
away. That means I've written roughly
500 columns when I take into account off weeks and the fact that for the first
6 or 9 months, my column was bi-weekly.
I remember when I wrote my first few columns, I would wax poetic about
how my father (Lenny Frome) had written nearly 1000 columns for a variety of
different publications. I remember when
I hit column number 100, I remarked how far behind I was. Now, my total count is probably about 600-700
columns and I can almost see myself someday surpassing my dad's total. That said, I definitely don't plan on taking
steroids or PEDs to get me there.
Part of what is so amazing about having written 500+
articles is that I have somehow managed to come up with that many things to
write about. I'm not really sure that
there are 500 unique subjects to write about.
I have to remember that if I borrow a subject from 2005 that there is a
strong likelihood that if someone reads it today, they didn't read that article
from 8 years ago. So, in that spirit,
I'm going to start back at the beginning today and discuss some basics about
video poker.
Video poker is truly a unique game in the casino. Far too often it is lumped together with
Slots, but there is little in common except for the technology. I don't think of a video blackjack machine as
a slot machine and the same is true for video poker. As the world starts turning more to online
gambling, the separation will no longer be about the technology. Instead it should be about the essence of the
game. Video Poker is a game that is
based more on skill than almost any other game in the casino. This doesn't mean that luck doesn't play a
part, especially in the short run. But,
if I were to challenge a random Player to a slot competition, there would be no
way to gain an advantage. If I were to
challenge a random Player to a video poker competition, I'd like to believe
that I would have a distinct advantage.
The longer the competition runs, the more strategy and skill will rule
the day and the less that luck will impact the results.
How is video poker a game of skill? Because the Player must make a decision that
will clearly impact his results. This
decision is frequently NOT of the 'no-brainer' variety. Technically, in the game of Casino War, the
Player must make a decision to - whether or not to go to War when the Player
and Dealer tie. But, the proper decision
is the same all the time - to go to War.
So, while technically, there is 'strategy', I doubt very many people get
this one wrong. In Three Card Poker,
there is one strategy decision - to Play or Fold. The decision is also relatively simple. If the Player has Q-6-4 or better, he should
Play. As simple as this sounds, many
Players don't follow this rule (and I don't mean that they go with Q-6 or Q or
better), and as a result, they give up a larger portion of their bankroll to
the casino than they need to.
Video Poker strategy is far more complex than this. First of all, the decision is not one of Fold
or Play, but rather which cards to Discard.
There are 32 ways that a Player can make each of these decisions,
ranging from keeping them all to discarding them all. Granted many of these possibilities will fall
into the brainless category. If you are
dealt Three of a Kind and two off-suit kickers, which cards to discard is
pretty obvious. If you are dealt a
Straight, then you don't have to discard at all. Oh wait, what if it is also a 4-card Straight
Flush or a 4-Card Royal, then what is the proper play?
If you are dealt the following:
4♦ 4♠ 5♠ 6♠ 7♣
the decisions get a bit more
complex. You might keep the Pair of 4's,
or the 4-Card Straight or maybe the 3-Card Straight Flush. This is 3 of the 32 ways the hand can be
played. The other 29 are quickly discarded,
so there isn't a need to go through 32 possible decisions for each hand. Obviously, you're not going to keep the
off-suit 4-7 in this case.
Unlike table poker (which involves even a higher level of
skill), the strategy in video poker is based strictly on math. You don't play hunches and you're not trying
to beat another Player. You don't have
to worry that you might pull your Straight and he might come up with a Flush. All that matters is the likelihood (aka
probability) of each final hand and how much that hand pays. But, I'll leave that for next week. For now, I'll be happy if I've convinced you
just a little bit that video poker is not slots.

(*Note: this column was written on the 3rd day of the recently completed government shutdown)
As we finish Day 3 of the government shutdown, it is hard
to find a news story that is about anything else. I was pleasantly surprised (initially) when
my eye caught a story on Yahoo's main news page that dealt with lotteries. Apparently, they were revealing the secret of
how to win the Powerball Lotto. Who
doesn't want to win Powerball? I read
the article, which was all of about two paragraphs.
It began by talking about last month's sole winner, who
won $400 million. He 'beat the odds' by
hitting the lottery which is a 1 in 175 million chance (I'll take their word
for this). Per the article, the odds of
getting struck by lightning is a mere 1 in 10,000 (again, I'll take their word
for this). Finally, the article gets to
the important question "How can you increase your chances of winning the
lottery?" Then they apparently
provide the way. A statistician in
Louisiana has discovered that certain numbers come up more often than others!
The most frequent powerball number is 20. The most common white ball numbers are 42,
16, 35, 26 and 19. There you have
it. The winning numbers! So, to increase your changes all you need to
do is play these 5 numbers with the number 20 and you can start spending your
millions! I didn't actually look up the
historical winning numbers, but I'm going to take a strong guess that this
particular combination has NEVER come up before, but undoubtedly they are on
their way.
Now, nothing in this article gives the actual frequencies
of these numbers. Nothing shows that
they show up an abnormally high amount of times. Let's assume that Powerball has been drawing
twice a week for 20 years. That is 2000
total draws. That is 10000 numbers drawn
(white balls) and 2000 red balls drawn.
There are 59 white numbers and 35 red balls. On average each white number should be drawn
169.4915 times. So, for all we know the
5 numbers he cited showed up 170 or 171 times while the rest of the numbers
showed up 169 times. Clearly a massive
statistical edge! On the red balls, the average is 57.14. So, 20 may have shown up a couple more times
that all the others. Again, a clear
statistical advantage!
I've always been strong at math. I realize not everyone is. I don't expect everyone to be. But, bad math packaged as an article on the
front page of Yahoo news really drives me absolutely nuts. To add insult to injury, the article went on
to suggest you should buy your ticket in Pennsylvania because that's where the
largest number of winning Powerball tickets have been sold. It doesn't even take into account the
possibility that more tickets have been SOLD in that state than many
others!
I've often said (semi-jokingly) that the world's largest
casino is the stock market. But, there
is one critical way that the stock market greatly differs from gambling. With stocks, past performance CAN BE used to
determine the likelihood of future performance.
While there are no guarantees, there are likelihoods. A stock that has paid a dividend for the past
100 years is not likely to stop paying it next year (barring any specific news
being known). Stocks have their ups and
downs, but you are NOT really dealing with random events.
The same cannot be said for what happens in a casino (or
a lottery). The last 3 numbers on the
roulette wheel could've been red and the likelihood of the next number being
red will still be 18/37 (or 38). The
last 10 numbers could've been red and the probability will STILL be 18/37 (or
38). The last 5 hands of video poker
could've contained the 2 of diamonds in the initial deal and the probability of
it showing in the next hand's deal will still be in 5 in 52. Nothing changes when we are talking about
the lottery. It does not matter if one
number has appeared more often than others.
Next week's numbers are completely random and each number has the same
probability of being drawn as the next.
Okay, I'll admit it.
Maybe I'm just jealous that after a decade of writing for Gaming Today,
Yahoo has not covered a single one of my columns, but some guy writes a
complete nonsensical piece of useless information and that makes their front
page. The sad part will be how many
thousands of people will read that article and actually run out to play those
numbers. There is only ONE way to
increase the likelihood of winning the lottery - buy more tickets.

Imitation is the Sincerest Form of Flattery
A couple of weeks ago, I two days walking the halls of the
Sands Expo at the Global Gaming Expo. If
I had to pick one word to describe the event, it would definitely be
"SLOTS". Like last year, I
think they dominated the show. For those
who have been reading me for years, you know my thoughts on Slots from a
Player's perspective. But, I do give the
slot manufacturer's a lot of credit for creativity. This year, they kept it up, not only in the
games that are being developed, but in terms of the marketing. There were zombies everywhere. I'm not sure if there was only one
manufacturer who had a zombie themed game or if there was more than one. But there were a lot of zombies in some really
good make-up all over the halls.
As much as I write about video poker in my column, my
real love is table games and that's what I'm at the show to really see. This year, brought a particular trend to its
apex (or perhaps more appropriate, its nadir).
Besides the three big table game companies (SHFL, Galaxy and DEQ), there
were virtually no new table games. I did
see a couple of other new games, but they were almost afterthoughts from gaming
companies involved in other aspects. I
saw exactly ZERO small independent game inventors showing any new games. I recognize that the cost of a booth at the
G2E is not cheap and could easily wipe out the budget of a small inventor, but
I always found it fun to talk to someone new about their game. I didn't get a chance this year.
I did get introduced to a few inventors who did not have
booths at the game who wanted to talk to me about their ideas. I find that most ideas seem to fall into two
categories. The first is the rather
'far-fetched' category. These are ideas
that aren't necessarily bad, but I have to wonder about their odds of
commercial success. One inventor
remarked to me about how all the casino games are poker-based. He found this to be problematic. I find this to be indicative of what is likely
to be successful commercially. It is NOT
that games that are not poker based haven't been invented and tried, it is that
none have ever had the staying power in the casino. Some might be fun and social for a few hours,
but they don't seem to have the ability to create repeat customers the way
poker-based games do.
The second common category of games are the
copycats. People look at a game like
Three Card Poker, which is undeniably the most successful proprietary table
game (both financially and in terms of number of tables) and try to emulate it
in some way. Now, many table games have
some form of patent protection on them (many do not!). But I am not talking about copying to the
point of patent violation. I'm simply
saying that people look at Three Card Poker as some magic formula and try to
replicate it. You know this is
happening when they begin describing their game with "It is just like
Three Card Poker but......."
For the past several years, the casinos have been going
through a Texas Hold'em craze. While I
think it has peaked overall, it has still left a lasting impression. Games that might have been developed as
7-card Stud games are being developed with 5 community cards in Texas Hold'em
style. After the dust settled, there are
currently 2 very successful Texas Hold'em table games. The first is Texas Hold'em Bonus Poker -
developed by Mikohn/PGIC and purchased by SHFL Entertainment a few years ago,
and Ultimate Texas Hold'em - developed directly by SHFL. I did the original math on UTH for SHFL. It was by far the most challenging game I had
ever worked on to that point and perhaps since.
It was also one of the most rewarding because of the success it has become. It is generally acknowledged as the 2nd most
successful game of all-time with several hundred tables in the market place and
is the only game on the horizon that has any chance to knock Three Card Poker
out of the number 1 spot.
Like Three Card Poker, one of the surest signs of the
success of UTH is how many times I have heard the phrase in the past few years
from an inventor, "It is just like Ultimate, but....." There is an old saying that imitation is the
sincerest form of flattery. I guess if
everyone is trying to create a game just like UTH, then UTH must be a pretty darn
good game. Is it possible to improve upon Three Card
Poker or UTH? I suppose it is
possible. But, 15-20 years after the
invention of Three Card Poker, it is not a minor improvement to Three Card
Poker that might take it out of the top spot.
It is a game that while still poker-based, introduce many new
concepts. It is a game that has more
uniqueness to it than similarity to Three Card Poker. I think if someone wants to knock UTH out of
the number 2 spot, it won't happen because someone tweaks UTH, it will be
happen because someone comes up with a new and better idea.
To all the inventors out there, don't think of new ways
to flatter the existing games by imitating them. Come up with new games with new ideas if you
want to make your mark.

What is the Allure of Progressives
There is a theory in physics that goes for every action
there is an equal and opposite reaction.
In gambling, there is a similar theory.
For every table game there will eventually be a sidebet. And, for every sidebet there will be a
Progressive version of the sidebet. The
math behind Progressives is probably the least understood math of any type of
gambling. It really isn't that hard once
it is explained properly, but I've worked with a lot of inventors on a lot of
Progressives, and it is fairly obvious to me that few people, even in the
industry, understand how a Progressive works mathematically.
Generally speaking there are 3 components of a sidebet -
the fixed pays, the seed and the contribution rate. Normally when we calculate the payback of a
sidebet, we simply multiply the fixed pays by the frequency of each winning
hand and sum up these values. For a
Progressive, we have to alter one step slightly and add one. For the jackpot event, we use the seed amount
as the equivalent of the fixed pay for that event. Each time it is hit, the casino is on the
hook to put that money back on the meter, so it is similar to a fixed pay in
that regard. We then need to add the
contribution rate - which is the amount of each dollar wagered that goes on the
meter - to the total payback calculated.
I'll save more details for another day, as this is not the point of
today's column. What is the point is to
discuss how a Progressive differs from other wagers.
While the top pay for most sidebets are pretty large, the
amount they contribute to the overall payback is usually pretty small. If you pay 1000 for a 1 in a million even,
the contribution rate is a meager 0.1%.
In video poker the Royal Flush contributes only 2% to the payback of the
game. If we were to look at most table
game sidebets, we'd probably find that most top pays contribute about 1-2% (or
less) to the overall payback. But, when
we switch to a Progressive, we find that the top pay frequently contributes
15-20% to the payback when we take into account both the seed and contribution
rate. What does this mean for the
Player?
As I said, the Royal Flush accounts for 2% of the payback
of video poker. What this usually means
is that until you hit one, you're only playing at about 97.5% which can be a
bit rough. When you hit one - and if you
are a regular player, you WILL hit one, you bring the theoretical payback back
to 99.5%. Hit the Royal more frequently
than 'normal' and you're likely up money as you will be above 100%. With Progressives, it doesn't quite work the
same way. That top hand is either more
rare or you'll be playing a game that deals much more slowly than video poker,
meaning that there are no guarantees that you will EVER hit it. So, even if the sidebet were paying 99.5%
like video poker, ONE PLAYER is going to wind up winning 15-20% of that payback
and everyone else will be playing at 77.5% - 82.5%.
When you consider the fact that many sidebets have
paybacks far lower than 99.5%, you realize that the picture for those that
don't hit the jackpot is even more bleak.
So, why do people play Progressives?
There are two main reasons. One
is a bit emotional and the other a bit more practical.
First, Players have always been willing to accept low
paybacks for a chance to win a life-changing amount of money. The Lotto has made a lot of money for a lot
of states. Most states payout only 70%
on their lotteries. This is lower than
the legal minimum of any casino game here in Nevada. But, for the chance, however slim, of winning
millions of dollars, Players are willing to throw a few dollars in for the hope
of getting struck by lightning.
The second reason deals with the way Progressives work
and makes far more mathematical sense.
To the casinos, the payback of a game is the long-term payback, which is
calculated as I described earlier.
You'll note that what I described completely ignores the specific value
on the meter at any point in time. This
money is merely an accumulation of the contribution rate over time. It really doesn't matter to them
(mathematically), if a jackpot that is supposed to hit about once a year,
doesn't get hit for 3 years. However, to
the Player, the payback of ANY wager is dependent upon the specific payouts for
each winning hand at the point in which you make the wager. It doesn't really matter if the contribution
rate is 10% of 20%. If a Jackpot which
is supposed to average $250,000, goes all the way up to $600,000 then the
payback at that point in time is WELL above the theoretical payback.
It is possible that at a particular point in time that
the payback of a wager could be over 100%.
At this point, it makes sense to play the game mathematically. The problem is, however, that it will be one
person that will benefit from this occurrence and it may not be you. Then again, it might!

Why Play Max Coins?
Generally speaking, I advise players to play max-coins
when playing video poker. For most
versions, this means 5 coins. The penny
Player puts up 5 cents, the nickel player 25 cents, the quarter player puts up
$1.25 and the dollar player has to put up $5 per hand. This is done for one simple purpose. On most video poker machines, the top payout
- the Royal Flush - changes from 250 for 1 to 800 for 1 when that 5th coins is
put in. If you are playing a
Progressive, the only way to win that jackpot is to play 5 coins.
A payout of 800 for 1 on the Royal is worth approximately
2% of the total payback of the machine.
A payout of only 250 reduces this down to about 0.65%. So, the Player is giving up more than 1.25%
of payback if he plays below max-coin.
In similar fashion, if the machine is offering a Progressive, which
should push the Royal payout to above 800, then the Player would be
surrendering even more payback by playing below the max-coin level.
The notion of playing max-coin does NOT mean you should
wager 5 times the amount you feel comfortable wagering. Instead it means you should consider lowering
your denomination to the next lower level and then play 5 coins. So, rather than playing 1 quarter, you should
play 5 nickels. This, of course, assumes
that all things are otherwise equal. It
is certainly possible that when you go to a nickel machine (or change to the
nickel option on a multi-denominational machine) that the paybacks may change
as well and you may find that the payback on the nickel machine is well below
that of the quarter. This makes things
a bit more complicated. If the quarter
machines pays 99.5% at max-coin, then it will be closer to 98% if you play 1
quarter. If the nickel machines pays
98.5% at max-coin, then you'll still be better off playing max-coin nickels.
There are a few times when you may want to play less than
max-coin. The first is when you are
first leaning how to play. As you are
more apt to make mistakes at this point, you might be better off simply playing
1 nickel at a time. Yes, you will be
playing at a lower payback, but at this point, your goal is to become a better
player while playing on a real machine.
Ideally, you'd spend most of your 'learning' time playing on your
computer (or phone or tablet) at home for free ,but I realize that playing for
free may be a lot less exciting than even playing for a single nickel.
Another reason that you may not want to play max-coin is
your bankroll. If your bankroll is not large
enough to support playing max-coin then you might be better off playing
single-coin. Once your bankroll is
gone, you're done and you need to make sure you have enough money available to
ride out the cold streaks. Of course,
one solution to this issue is again to simply drop down in denomination. So, this advice really only applies if
machines of a lower denomination are not available. Since the advent of the multi-denominational
machine, finding machines that play the denomination you want to play has
become much easier, however. So, this
second reason may have limited practical applications. But, if you find yourself in a situation
where your bankroll will support 5 nickel play, but you only have quarter
machines available, you may want to consider playing a single quarter as
opposed to five quarters.
One critical point to consider. Just because you switch a machine from
quarter play to nickel play, do NOT assume that the paytable is the same even
if you are switching to the same variety of video poker. There are no requirements that state that a
machine must use the same paytable when you move from one denomination to
another. In similar fashion, don't
assume that a bank of similar (or identical) looking machines all have the same
paytable. Casinos frequently and
presumably purposefully mix the machines up, making sure to sprinkle higher
paying machines in with lower paying ones.
I dare say that you may find no rhyme or reason to the pattern of
machines on the casino floor.

Better is Better than Best
A long time ago, I remember reading an article about
product marketing in which it stated that you'll never (rarely?) see a company
say that there product is better than a similar product. Why?
Because if you say something is better you have to prove that it is
better. If you, on the other hand, say
your product is the 'best' product then it is possible for the other product to
be 'best' too. Best, in marketing
parlance, simply means as good as, whereas, better means superior. So much for those Run, Spot, Run books which
talk about good, better and best. In
marketing it is more like good, best and better.
As bad as it is in the English language, I think it gets
even worse when it comes to math. You
can make numbers say just about anything you want them to. In the past couple of years, much has been
made about the 1% (or is it 2%) of the country that is the wealthiest members
of our society. Then there are those
that focus on the remaining 99% (or is it 98%).
I don't get political in this column, so please understand I am making
no political commentaries here - only mathematical ones. A friend of mine posted up on Facebook the
other day some statistics about what happens if you look at the top 1% of the
world instead of just the U.S.A. All of
a sudden a very significant portion of the country is in the top 1%. Which statistic is more relevant? I know people who are millionaires who think
they are doing 'ok' and I know people who make very modest salaries who are as
happy as can be. The relevance is more
likely in the message that someone is trying to send rather than anything
absolute.
In the case I just discussed, I'll assume that all data
presented was reasonably accurate. A
such, no lies were told. No
misinformation was disseminated. Data
was simply presented in a way to try and get some particular message
across. A few months ago, I wrote a
column in which I asked if the U.S. has had a Democrat or Republican President
more. In the past 5 years, it has been a
Democrat. But in the last 8 out of 13
years, we had a Republican. But, in 13
of past 21 years, a Democrat. In 20 of
Past 33 years, a Republican. I can keep
going backwards through the 20th century.
Someone attempting to make a political point is likely to use whichever
statistic backs his point the best, even though it may have only minor
relevance to the point.
When it comes to gambling, the numbers can be manipulated
just as much, if not more so. If I had
to take a guess, I'd say that the average video poker machine in Las Vegas
probably has a payback of 97%. Now, if
I'm a casino whose average video poker payback is only 96%, I might put
together some advertising that simply says 'come to Vegas where the video
pokers pay an average of 97%!' . The
implication is that the casino pays this as well, but that's not what they
said. On the other hand, a locals casino
that likely has a significantly higher average payback is much more likely to
say 'come to the XXX casino, where OUR video poker machines payback
98.5%'. Of course, we don't really know
how they calculate these averages. With slot machines they simply can present how
they paid in the prior month because there is no human error involved. With video poker machines do they simply take
a straight average of all their video poker paytables? Do they weight $1 machines more than nickel
machines? Maybe there is a uniform
method for doing this or maybe they have enough wiggle room to give you
whatever number they feel will send the right message.
Of course the 'average' payback has very limited value to
an Expert Player. In the simplest
example, let's assume we have 2 casinos with 2 video poker machines each. One casino boasts a 98% average and the other
a 97% average. So, should you head over
to the one with the higher average? What
if their 2 machines each have a 98% payback.
But the other casino has one paying 94.5% and the other paying
99.5%. The only machine out of the
bunch worth playing is this last one, even though the casino's average is lower
than the others.
One of the local casinos here boasts of having the most
machines paying over 100%. I'll assume
that they are telling the truth with this, but that doesn't mean that their
machines don't pay 100.01% and that all of the machines below 100% pay
96%. Now, to the experienced Player you
will still happily seek out the 100.01% machine, but this doesn't mean that you
can just show up and sit down at any machine and know that you are playing
100.01%. At the same time, you would be
better off finding a 101% machine at another casino that may have only 3
machines of this type and whose average machine pays 96%!
So, what's my point?
Don't be sucked in by numbers that can be made to say anything they want. The payback of a machine is an absolute
number, calculated with mathematical certainty.
It doesn't mean that every time you play (even if it is for a few
hours), that you will experience this payback.
It does mean that over time, your experience should begin to approximate
this theoretical payback, assuming you are using the right strategy. When you look at the paytable on a machine,
that tells you the payback of the machine.
This is all that matters.
Marketing numbers that the casinos produce are just that - numbers they
produce. After all, why trust the group
that has actually made better, better than best?

Think Loss Rate
How much of a difference is there in terms of payback
from one casino game to another? Most
table games have a payback between 97 and 99.5%. Video Poker can range from about 95% to
101%. Slot machines probably range from
about 85% up to 95%. Sidebets, quite
frankly are all over the place, ranging from just over the legal limit of 75%
and going up to the low-mid 90%. While
there is a lot of overlap, one of the largest determining factors is
strategy. More complex strategy means a
combination of more human error and/or Players not even trying to follow
it. Simple strategy is much easier to
learn and follow. Three Card Poker has
one simple strategy rule. Follow it and
you should approach the theoretical payback of about 98%. Don't follow it and you can only do worse.
Video Poker has paybacks considerably higher. Not all of the versions, but you can still
find plenty of them well above 98%.
Video Poker's strategy, however, is far more complex than Three Card
Poker's strategy. The average Video
Poker machine has more than 30 different strategy items that need to be
memorized and in the appropriate order so that you know how to play the hand. So, first you need to review the hand and
determine the realistic ways the hand can be played and then you have to know
which of these ways has the highest expected value, which tells us which way
the hand should be played.
In most games, many of the hands are pretty obvious even
if you knew little. If you're dealt a
6-7-8 in Three Card Poker, I don't think you need to have read a book to know
what to do. What if you are dealt
K-3-2? What about Q-8-2? What about Q-3-2? For each hand, the Player is really asking
himself if he is better off Playing or Folding.
Those are the only two options in Three Card Poker. The answer is pretty obvious for the Straight
and a good deal less obvious for the other three hands. The strategy is determined by the math behind
the question of whether the Player is better off Folding or Playing. By Folding, the Player forfeits his original
wager (one unit). By Playing, he wagers
an additional unit. If Playing can
return at least that additional unit (on average), then the hand is worth
Playing. The Player does not have to perform
some complex calculation on each hand.
The decision is to Play or Fold and the math works out very neatly. For every hand stronger or equal to Q-6-4 the
Player is better off Playing. For Q-6-3
or less, he is better of Folding. You've
just become an expert at Three Card Poker strategy.
Video Poker is not nearly this simple. First of all, there is no folding and no
additional wagers. You make an original
wager and your only goal is to maximize the amount of money you get back on
average for each hand. If you're dealt a
Straight off the deal, there isn't much to think about - unless of course it is
also a 4-Card Straight Flush or a 4-Card Royal - then what? What if you're dealt Three of a Kind and
3-Card Royal? How about a Pair and a
4-Card Flush? Does it matter if it is a
High Pair or a Low Pair? (Yes, it
does!)
In Video Poker, the hands are categorized into about
30-40 different hand ranks and partial hand ranks. Each of these is assigned an expected
value. This expected value is calculated
by looking at ALL the possible draws for that hand and tabulating the total
units won for each final winning hand.
We then divide this total by the number of possible draws so that we can
compare apples to apples. So, to look at
a simple example. Suppose you are dealt
the following hand:
4♥ 5♥ 6♥ 7♥ 8♦
The decision here should NOT be driven by your favorite
Clint Eastwood line ("are you feeling lucky, punk?"). It should be driven by the math. The straight has an expected value
("EV") of 4.00. There is no
draw in this case and the EV is simply the payout of the hand. If you decide to discard the 8, there are 47
possible draws. 2 will result in a
Straight Flush, 5 will result in a Straight (remember that you would have
discarded a card that could also have made it a Straight) and 7 that will
result in a Flush. All other cards
result in a losing hand. So, do you
throw away the sure 4 units to go for the Straight Flush? When we add up the payouts of the winning
hands, we get 162 units (2 x 50, 5 x 4, 7 x 6).
We divide this by 47 (the number of possible draws) and get 3.45. As this is less than the EV of the Straight,
we keep the Straight. In the long run,
this will be the better move.
While most Player would play this correctly (I guess?),
the simple reality is that except for those that learn the right strategy,
there will be a significant number of Players who will NOT play this
correctly. Throw in the roughly 25% of
hands that require a real decision and the casinos can count on Player error to
help pad their winnings. This is why
they can offer the 99.5% paybacks on so many full-pay jacks or better Video
Poker. Someone like myself might sit
down and get the 99.5%, but the vast majority of Players will play well below
this level. They are likely to play in
the 97-98% range if they have some idea of what is going on and perhaps as
little as 95% if they just 'wing it'.
The difference between 99.5% and 96% may not seem like a lot, but I
always suggest you turn that around to the loss rate - 0.5% vs 4%. Now there is a 700% increase from one to the
other. The impact to your bankroll could
be staggering.
