EV, Dont understand.

[Kurn, son of Mogh]

In the example I posted above where the pot = $14 and you need to put in $2 to call, the EV is +$0.80 (each time you call you theoretically win $.80).

In that example with $14 in the pot that you stand to win ~20% of the time, your pot equity = $2.80.

EV is the long term value of the play, pot equity is the value you have in the pot right now.

The example is a bit simplistic. Pot equity calculations come into play more when facing a decision of raising with a hand that is not the best right now in order to thin the field or buy a free card and thus either increase the probability of you winning the pot if you improve or to give you two chances to improve and win.
