Expected
Value (EV) in Poker is a very misunderstood concept.
Our intention here is to explain “expected value”
as simply as possible and to make you a better poker player
by using expected value theory in your decision making process.
Without going into a technical definition here is an example
of an event that will have a zero expected value over time
(EV = 0.00) so as to make this idea clear in your mind.
Let’s say I asked you to pick a number between one
and twenty and that each time you got it right I would pay
you $20. You would expect to be able to correctly guess
the number once out of every twenty tries. If I were to
charge you $1 for each guess and you guessed at the number
millions of times then the expected value under these circumstances
would be zero. You would win $20 every twenty tries and
since it would cost you $1 each try you would end up winning
$20 for each $20 you gambled. If on the other hand I charged
you more than a dollar for each guess you would be silly
to bet against me (your expected value would be negative)
and if I charged you less than a dollar for each guess then
you would want to play against me all day long for the rest
of your life. To put this idea into gambling terms you know
that in Roulette there are 36 numbers and usually a 0 and
even a 00 on a table. Clearly your EV would be zero if the
casino paid you 37 to one (plus your original bet back)
or 38 to one in total but in fact they give you 35 to one
on your bet (and your bet back) so your expected value to
make money over time is negative. And that is assuming you
are betting on only one number for each spin. If you bet
on multiple numbers on the same spin of the wheel then your
expected value is even worse.
OK now you have a feeling
for what we are talking about. How does all this relate
to playing Texas
Holdem Game? Glad you asked. In Texas Holdem the expected
value of your first two cards depend on the cards you have,
your position on the table, and the number of players at
the table. In other words you will be happy to know that
in the dealer position (on the button) pocket aces yield
an EV of 2.96 when there are ten players at the table. This
data is based on real data compiled over millions of hands
and in real money games. So in the case of our AA in the
dealer spot it goes without saying that you will make loads
of money with pocket aces. Course we have all lost pocket
aces but more often than not we will win the hand and if
you have ever played Texas No Limit Holdem then you know
that going all in pre-flop
with pocket aces is the only time you can be sure to have
the one up on all other players in the hand before you have
seen a single card. It is expected value theory in Texas
Holdem that can help you make a decision to go all in pre-flop
(or not). Sometimes you are in a Texas Holdem Tournament
and you are running out of chips and it is time to make
a bold play (like the all in play). Wouldn’t you rather
make a decision that at least you know that in the long
run you have a positive expected value with a given hand
and not a negative expected value? Sometimes it is just
this little difference and this little bit of information
that can help you stay in the Tournament until you are in
the money as opposed to busting out early. We have taken
the liberty to give you all the expected
value data for 10 players all the way down to 2
players so that you can make an educated decision in
the game at the crucial time instead of gambling blind on
any two cards that are yours to play. Ultimately the all
in play is the one situation the more talented Texas Hold’em
players prefer to avoid in a pre-flop situation (unless
they have pocket aces) and by using the all in strategy
you will be able to improve your standing in a Texas Holdem
Tournament without seeing a flop (hopefully). This is assumed
that nobody calls your all in and that you pick up the blinds
without a challenge.
As a rule the better
the expected value of your first two cards in Texas Holdem
the better the chances of you eventually winning the hand.
In other words if you have an EV of 1.00 your bet in this
situation will get you much more money more often than not
as represented by such a strong expected value. You must
note that even hands with an EV greater than 1.0 will lose
sometimes. But in the long run you will make money with
them. Actually the hands with an EV = 0.00 will break even
over time so we suggest that you play the two first cards
with a positive expected value as often as you can (depending
on the situation). If you are in the dealer position with
JJ and three people have gone all in for more chips than
you have in total and it is your turn to play then you should
fold immediately since there is a good probability that
someone has a better hand and even though the EV of JJ in
the dealer position is 0.89 you have to know that you are
up against some very powerful hands.
In the above example
we gave you the expected value of JJ in the dealer position
in a ten player game. Below you will note the expected value
of hands in a ten player game in the dealer position:
| AA |
= |
2.96 |
| KK |
= |
2.09 |
| AK (suited) |
= |
0.99 |
| AK (not suited)
|
= |
0.61 |
| QQ |
= |
1.36 |
| JJ |
= |
0.89 |
| 1010 |
= |
0.56 |
| AQ (suited) |
= |
0.64 |
| AQ (not suited)
|
= |
0.37 |
| KQ (suited) |
= |
0.42 |
| KQ (not suited)
|
= |
0.17 |
|
If you habitually play
hands with large negative expected values you should not
be surprised that you are losing more than you win. For
example here are some seemingly good and bad starting hands
in Texas Holdem and their associated negative expected values
(in a ten handed game in the dealer position).
| A5 (not suited) |
= |
-0.13 |
| A2 (not suited) |
= |
-0.14 |
| K2 (suited) |
= |
-0.12 |
| J5 (suited) |
= |
-0.11 |
| 87 (not suited) |
= |
-0.08 |
| 62 (suited) |
= |
-0.10 |
| 43 (suited) |
= |
-0.11 |
|
To show you the difference
position makes in expected value please note below the same
hands in the big blind position for a ten handed game:
| A5 (not suited) |
= |
-0.30 |
| A2 (not suited) |
= |
-0.35 |
| K2 (suited) |
= |
-0.22 |
| J5 (suited) |
= |
-0.23 |
| 87 (not suited) |
= |
-0.31 |
| 62 (suited) |
= |
-0.32 |
| 43 (suited) |
= |
-0.22 |
|
In other words in the
big blind an 8 7 off suit is much worse (you will lose much
more money over time playing this hand) than in the dealers
position.
