I'm getting a little confused studying Poker Combinatorics.
(a) Some suggests comparing Pot Odds with [Combinations you beat - calling this equity%].
(b) Some suggest comparing Pot Odds with [Hero's hand vs Range - call this equity%].
Example of (a)
Pot odds: 2:1 = 33% Total combinations = 42 Combinations you beat = 33 (79%) Combinations you don’t beat = 9 (21%) Seeing as you have the best hand 79% of the time (or 79% "equity") and the pot odds indicate that you only need to have the best hand 38% of the time, it makes it +EV to call.
Example of (b)
Will be too long to post. Basically find equity vs range of hand and then calculate average equity using combinations.
So.. uhm which one is it?
