If an opponent has a draw that he will hit 1/3 (2:1 against him making it) and you make a bet that gives him 2:1 odds to call, and you play that hand thousands of times, won't your net gain be zero? Doesn't that make your EV = 0? How can giving someone good odds to draw be +EV just because you're the favorite? In the long run you will lose money by making bets that give your opponents better odds than they need to draw. Do i misunderstand the concept of expected value? I have always been under the impression (wrongly it seems?) that Expectation was only relevent in the long term.
