Pot Equity – Poker 101 ( Extremely Simple Math)

Pot Equity is defined as our percentage chance of winning the pot when in a hand. We can define our equity from preflop all the way until the river and once we know what our opponents has in his hand (oftentimes we have to estimate what he may have). We can define equity against either a single hand or against a range of hands which our opponent could possibly hold.

Pot Equity in practice

For calculating our equity we need to use a piece of software such as equilab. There is lots of other software out there that can do the same job; but equilab is free and easy to use.

Pot equity – AA v QQ preflop

If we want to see how AA performs vs QQ we can just plug it into equilab:

81% of the time AA will win and 18% of the time QQ will lose.

We can then compared that on a random flop and turn and see how the equity changes:

ON a KhJh7c board QQ has almost 11% equity vs AA:

Pot equity – AA v QQ on the flop

On the turn of Ts the equity increases to almost 14% due to the straight draw possibility:

Pot equity – AA v QQ on the turn

We cannot compute equity vs a single hand on the river as since there is no more cards to come. Thus hand values will not change further. However, it is possible to calculate equity vs a range of hands. For example we may think our opponent could have AA, AK and some bluffs such as A9 which we can calculate our equity against.

Pot equity with a real example

To take an example let’s look at the hand shown previously:

Poker pot equity 4

In this situation we expect villain to have some hands such as AA,KK,QQ, JJ and possibly TT. We believe he will play the hand by betting the flop turn and river. He will also have 33,55 and 99 although 99 being likely since we have a 9 in our hand. We also think villain will bluff some of the time; let’s assume he bluffs with AK, AQ, AJ, AT, KQ, KJ and QJ all of clubs. If we sub this into equilab we find we have an equity of almost 18%:

Pot equity – A9s v range

Our equity of 18% isn’t particularly good and if we call we will expect to lose the majority of the time. We will see in the next section that calling will be unprofitable.

Equity realization is another important concept which is a measure of how much equity you will actually get to see. Here is a great article by PokerNerve on the subject to help you get a handle on it.
