Pot Odds

Gotta Get that Paper, Dog
This could be yours, if you calculate your pot odds correctly.

Pot odds are a crucial deciding factor in poker play.

Pot odds refers to the relationship between the size of the pot and the size of the bet. For example, if there is $10 in the pot and you have to call a $2 bet, then you are getting pot odds of 5-1. If you have to call a $5 bet in the same $10 pot, you are getting pot odds of 2-1.

We recommend that you use a pot odds calculator to instantly display your pot odds when you play online poker.

The Size of the Pot

You should always be aware of pot size. If you are playing Limit poker, you count the number of bets in the pot instead of the amount of money. When the bets double, as in Hold'em, you count the big bets as two small bets. If you are playing Pot-Limit or No-Limit, it is a little bit harder to count the pot and, as a result, the odds will not be as exact. Regardless, you must still do it.

How to Use Pot Odds

Once you know your pot odds, you must use this information appropriately. You do this by connecting the pot odds to the value of your hand. This means you are able to put your opponents on likely hands and understand your chances of making a better hand than theirs.

For example, you have a flush draw on the flop in Hold'em and you are up against an opponent who you think has at least top pair. There are nine cards (usually referred to as outs) that will give you a flush when you have flopped a four flush.

As you can see in the table below, nine outs give you a 35% chance (2-1 against) of making the flush on the turn and river combined. This means that you need at least pot odds of 2-1 to call a bet on the flop.

Is this the pot you expect to win?

Implied Odds

Implied odds are defined as the relationship between the size of the current pot and the pot you are expected to win. This means that occasionally the pot does not lay the correct odds even when you decide to play because you expect to get further action and win more when you hit your hand.

For example, in Limit Hold'em your opponent bets $20 into an $80 pot and your call gives you pot odds of 5-1 since you are risking $20 to win $100. But, if you expect your opponent to call a bet or raise on the river if you make your hand, your implied odds are 6-1 or 7-1.

A Rule of Thumb for Hold'em and Omaha

Every out gives you an approximate 4% chance of hitting on the turn and river combined. For example, five outs give you about a 20% chance of improving, six outs about 24%, etc.

Simplified:

Use the rule of 4 if you are shoving on the flop (4x your number of outs).

Use the rule of 2 if you are calling on the flop to see the turn (2x your number of outs), or calling the turn to see the river.

Morten, you are absolutely correct. Fixing that typo now.

PS. I didn't write this article ;)

Morten Hard 2009-08-18 00:50:00

Under 'Implied odds' you say.: $20 to win $120

Isn't that supposed to be $20 to win $100?

The first ex. is odds 6-1 not 5-1 like stated in the article.
