POT ODDS AND "OUTS"
Probability and odds are huge factors in Texas Holdem.
Players use odds to determine their actions. The chances of
finishing a flush or a straight, the probability of getting an
over card, the percentage of times you're going to flop a set
to match your pocket pair are all important factors in
poker.
Knowledge of these statistics is a key to winning. In online
games especially with very few (if any) tells, statistical
knowledge becomes the main factor when choosing whether to bet,
call, or fold.
Pot odds decisions are one of poker's most elementary,
yet it is one of the most common mistakes made by amateur
players at all levels.
You will most likely always find a player who is making bad
pot odd decisions or ignoring them entirely, meanwhile paying
off the rest of the table!
In Texas Holdem, you commonly use outs and pot odds the
most. This is also the starting point for those who want to
learn about poker odds. To those out there who "ain't good at
countin' much", you better get good because that is how it's
done.
Outs are defined as a card in the deck that helps you make
your hand. At this point it's only simple division.
The numerator (top number) will be the number of outs you
have. The denominator (bottom number) is the number of cards
left that we haven't seen.
The result will be the percentage chance of making one of
those outs. Therefore, the most math you'll be doing will be
dividing small numbers by 50 (pre-flop), 47 (after the flop),
or 46 (after the turn)
Pot odds are as easy as computing outs. You compare your
outs or your chance of winning to the size of the pot.
If your chance of winning is significantly better than the
ratio of the pot size to a bet, then you have good pot odds. If
it's lower, then you have bad pot odds.
For example, say you are in a $5/$10 hold em game with
Jack-Ten facing one opponent on the turn. You have an outside
straight draw with a board of 2-5-9-Q, and only the river card
left to make it.
Any 8 or any King will finish this straight for you, so you
have 8 outs (four 8's and 4 K's left in the deck) and 46 unseen
cards left.
8/46 is almost the same as a 1 in 6 chance of making it.
Your sole opponent bets $10. If you take a $10 bet you could
win $200.
$200/$10 is 20, so you stand to make 20x more if you call.
1/6 higher than 1/20, so pot odds say that calling wouldn't be
a bad idea.
The next step is to use bet odds and implied odds. That's
tougher, because it involves predicting reactions of other
players.
With bet odds, you try to factor in how many people are
going to call a raise. With implied odds, you're thinking about
reactions for the rest of the game. One last example on implied
odds.
Say it's another $5/$10 hold em game and you have a four flush
on the flop. Your neighbor bets, and everyone else folds.
The pot is $50 at this point. First you figure out your
chance of hitting your flush on the turn, and it comes out to
about 19.1% (about 1 in 5).
You have to call this $5 bet versus a $50 pot, so that's a
10x payout. 1/5 is higher than 1/10, so bet odds are okay, but
you must consider that this guy's going to bet into you on the
turn and river also. That's the $5 plus two more $10 bets. So
now you’re facing $25 more till the end of the hand.
You have to consider your chances of hitting that flush on
the turn or river, which makes it about 35% (better than 1 in 3
now), but you have to invest $25 for a finishing pot of
$100.
$100/$25 with 1 in 4. That's pretty close. But there's
more!
If you don't make it on the turn, it'll change your outs and
odds! You'll have a 19.6% chance of hitting the flush (little
worse than 1 in 5), but a $20 investment for a finishing pot of
$100! $100/$20 is 1 in 5.
So the chances would take a nasty turn if you didn't hit it!
What's makes it more complicated is that if you did hit it on
the turn, you could raise him back, and get an extra $20 or
maybe even $40 in the pot.
Is there an easier way to calculate pot odds?
Thankfully, there are several short cuts that have been
devised to make a quick judgment for pot odds.
One of the easiest methods is to take your total outs,
multiply times 2, and then add 2.
This is roughly a percentage chance of making your
hand.
For example, say you have an inside straight draw with 4
outs. 4x2 = 8. Add 2, for a total of 10.
You have roughly a 10% chance to make your hand. Your
call should be no more than 10% of what is already in the
pot.
This method is quick and decently effective, though certain
calculations will be a bit off. This method does not
take into consideration the fact that you may have more than
one card remaining to come; it simply estimates your chance of
hitting your "out" on your next card.
There are a number of tools online that help you calculate
your odds. Just do a Google search, and you’ll find
several.
Keep in mind, though, that using them may significantly slow
your play and cause your fellow players to interpret this as a
"tell".
Playing your pocket cards is key, but you’ll also need to
know some strategies when it comes to the flop and the
river.
