Reference hand from last night that contributes to this discussion somewhat:
Folds to me on BTN and I haz J
J
and open 10 at 1/3, SB fish and BB OMC call. Flop As 7s 2c SB open folds x x Turn 9s OMC bets 20 into 30 I CALL getting 5:2 with a 4-card FD and 2 Jacks 11 outs one time ~22% but need 28.5% to break even so need to win 30$ OTR to make profit.
Thought about it after, would OMC ever pay off 30$ on a 4 flush? He sometimes even has a higher spade. And he always had at least an A.
