Poker - When to bet out on the
flop.
A poker article by Peter Birks at
BETDIRECT POKER for Easy Play Games
The standard play in mid-limit
poker when you have been reraised and find yourself out
of position on the flop is to check to the raiser, no
matter what the flop. Like most standard plays, it has
its grounding in logic. Reraisers usually have very
strong hands, so, even if the flop is favourable for you,
you can still check, comfortable that your opponent will
bet. Then you can decide whether to "pull the
trigger" on the flop, turn or river. If the flop is
unfavourable, a bet out is unlikely to push your opponent
off his hand.
However, like all standard plays,
there are a number of exceptions. Let's look first at a
common mistake made by players who have defended their
blind with, say, a low pocket pair, finding a flop of
Ace-x-x rainbow. They bet out, thinking that they are
"representing" an ace, and that they might
force an opponent with a high pair out of the hand.
This rarely works. First, your
opponent is slightly more likely to have raised with an
Ace and a high kicker than he is to have raised with a
high pocket pair (36 combinations of AK/AQ/AJ, 33
combinations of AA down to 99). Secondly, if your
opponent does indeed have a high pocket pair, he is going
to think to himself: "Hang on, why is this guy
betting out rather than checking? If he had a very good
hand he would be looking to check-raise. If he had an Ace
and a bad kicker, he would probably check-call. Therefore
he has nothing, probably a low pair. I shall raise!"
Betting out from the blind (or
when out of position) into a raiser or reraiser is
normally only correct when there is more than one
opponent. Curiously, players will often go for the
check-raise (the "standard" play) when to do so
puts them in grave risk of losing a hand that they would
otherwise have won.
Here's an example when the
non-thinking, automatic play would be to go for the
check-raise, but when to bet out is correct.
$3-$6 Limit:
Big Blind(BB):
You: $200:
9d 9c Middle Position 2 (MP2):
$23 Button: $200
It's late at night US time. MP2
has shown himself to be loose and aggressive. Possibly he
is on tilt (you have only recently sat down, so you have
no idea how much he has lost).
The hand is passed round to him
and he raises to $6. The button, a solid but
unimaginative player who is good enough to win a bit at
this level, but would probably lose at $5-$10, calls. You
also call. $19 in the pot.
The flop comes.
3c 6h 6c.
You put the loose player on
virtually anything, while the button is likely to have
either a modest pair (8s or less) or two highish cards,
or suited connectors of 67 or above. In other words, you
are probably in front at the moment. You are 99% sure
that MP2 will bet out, so you go for the check-raise,
right?
Wrong.
What you would really like here
is to be up against the short-stacked guy, who looks set
to blow the rest of his money on this hand. If you check,
MP2 will bet and the button will probably call even with
just overcards. You then raise, MP2 calls and Button is
now getting odds to call.
However, if you bet, MP2 is
likely to raise you, which makes it much harder for the
button to call. Even if he would be willing to come in
for $4, he cannot be certain that you don't have a six,
which means that he risks a three-bet from you.
By betting out, you get yourself
heads up against the loose player. It's a kind of
isolation play where the loose player has to play his
part. But, they usually do.
A second advantage to this play
is that, if the button has some kind of miracle hand
(say, 67 suited, giving him trips), he is likely to
three-bet here, because he will be scared of your hand
being a flush draw. If he does three-bet (remember, we
already have him tabbed as a solid, unimaginative type),
then you have to fold your nines through gritted teeth.
In this particular case,
everything went (sort of) according to plan. The button
folded. The turn brought a board of 3c 6h 6c 2d and I
check-raised him all-in (if my opponent has the 54 or the
six, then good luck to him).
The river brought 3c 6h 6c 2d 5s
and opponent flipped over some rubbish like T7 off.
In this particular instance, I
would probably have won anyway, because the button would
not have hit one of his overcards, but your expected
profit is greater if you isolate the loose opponent.
The
counter-argument:
Ahh, I can hear themore astute
among you say, "but if you check, MP2 bets, button
calls, and you raise, MP2 is likely to three-bet it,
forcing out the button and winning you an extra
bet".
It's a seductive line and one
that I can only rebut by personal experience. At this
level, once a player decides to come in for one bet, they
are far more likely to stay in for three bets than if
they are not in for any money (this round) and are then
asked to come in for two bets. There is a slight
mathematical backing for this line, since your pot odds
once you are already in for one bet are slightly better.
But the reality is that players will often fold for two
bets (provided they have not yet contributed to the pot
this round), even though the pot odds favour a call,
whereas they are likely to call for three bets (provided
they have already contributed a single bet this round)
even if the pot odds favour a fold.
The second
counter-argument:
But why just go for the small pot
against the short stack? You are less likely to win
against two opponents, but the pot is correspondingly
bigger to compensate!
This argument falls down because
the size of the pot does not increase to the same degree
as the likelihood of the extra opponent defeating you.
This is because there is already some of the button's
money in the pot when you get him to fold. Let's suppose
in this example that the button has QJ and MP2 has
something slightly better than the garbage he turned over
say, KT. And let's give both of them a
runner-runner flush chance.
If you go for the check-raise and
are called on the flop, but not on the river (unless your
opponents pair), then you have a 52% chance of winning
and expect to win an average $43 pot just over half the
time for an expected value of $15.
If you bet out and isolate the
single opponent, you win an average $50 pot 73% of the
time for an expected value of $21.
It's possible to dispute the
numbers on a marginal basis (for example, we can't be
quite sure what the button will do on the turn if he
misses, and the first example requires that you do not
make a "crying call" if an overcard comes on
the end and the button bets) but the positive expected
value definitely favours isolating the single opponent.
