(low-probability poker
events)
Steve Brecher
September 19, 2005 While playing on Full Tilt Poker, I have said that there are three
topics I won't discuss in table chat; politics,
religion, and whether online poker is rigged. That's
because many people's opinions on those topics are
hardened and not amenable to friendly or productive
discussion.
Away from the table, I'll venture a couple of
comments about improbable events in poker. While not
direct instruction in the poker tactics and poker strategy of play,
these comments may help you take "bad beats" in stride
-- and that, in turn, is an essential part of poker
maturity.
First, let's consider what most would view as a
typical "bad beat" -- a lower pocket pair winning
against a higher pocket pair in holdem, such as KK
beating AA. When those hands share one suit, the chance
of the worse hand winning is about 18%. The chance of
the lower pair winning twice -- that is, the next two
times that such hands happen to go against each other --
is about 3%. If in one session of play, a lower pocket
pair beat a higher pocket pair twice, that might seem a
little, well, weird to some poker players.
Consider another situation involving chance. When two
dice are thrown, the chance of rolling "snake eyes"
(1-1) is about 3% -- about the same as a lower pocket
pair beating a higher pocket pair twice.
Suppose there were 600 craps tables using standard,
unaltered dice with nine players around each table -- a
total of 5,400 players -- and these tables operated for
a three-hour "session." How many players would observe
snake eyes being thrown at least once? The statistical
expectation result is not important. The point is that
it's easy to intuitively see that a large number of
players would.
Further, do you think some players might see snake
eyes thrown several times in an evening -- say, three or
four times? (That is equivalent to six or eight poker
"bad beats.") And if some of those players would be
inclined to report their observation on forums and in
chat, then it might seem to some as if the dice were
"fixed."
Let's go back to poker. Recently, I played a hand of
No-Limit HoldEm on Full Tilt Poker. An opponent four
seats in front of the button open-raised pre-flop. It
was folded around to me in the big blind, and I called.
I semi-bluff check-raised the flop, continued with a
semi-bluff bet on the turn, was raised all-in, and
called the raise. I made my draw on the river. After the
hand my opponent chatted:
opponent: ur horrible steve
opponent: why the [****] did u call that?
opponent: horrible that this site rewards that
(Confidential to opponent: I know these comments were
made in the heat of the moment after a big loss and
don't necessarily reflect your considered view.)
Let's take a look at my call on the turn. I held Ad
Td; my opponent held Kd Kc. The board was Qd 9d 7h Jc.
With my opponent's actual holding, I had 16 outs to
win the pot on the river, making me a 1.75 to 1
underdog. Of course, it could have been worse for me
against other holdings, but even the worst case for me
would have been to be up against K-T (a made straight),
and then I would have been only a 3 to 1 underdog.
After my bet and the opponent's all in-raise, I was
getting pot odds of 3.7 to 1 to call, so the call is
clearly correct. But it seemed to my opponent -- and to
at least one observer -- that I made a bad call, and
that my winning with a 36% chance to do so when I called
was a bad beat for my opponent.
The moral of this story: While "bad beats"
(low-probability events) do occur, sometimes a closer
examination of a poker hand can change first impressions
and allow you to continue to play with a cooler, clearer
head.
