He cant have a hand all that often here, and if I call flop with something like OESD and a BDFD and jam the turn on any card how do I calculate the math? My thoughts were as follows If I open on the button SB folds and he raises to 10bbs, I call Pot = 10+10+0.5 = 20.5 He cbets 11, I call. Pot = 11+11+20.5 = 42.5 On the turn he cbets 22, pot is 64.5, I jam my last 79 over the turn bet So, the odds assuming that when he calls I always lose are 79 : (64.5+79) Or about 55% For this example lets say I flopped an OESD and turned a backdoor flushdraw. So roughly 25% equity on the turn. This is probably wrong, but do I simply take the 25% of what I "own" in equity of the pot from what I am risking? ie .25 x 143.5 = 35.88 79-35.88 = 43.12 So, finally… Real equity adjusted odds are 43.12 : (64.5+79) Or about 30% Last edited by Hitablock!; 05-29-2012 at 04:17 PM.

(your 3 pre + his 10 pre + 11 on flop + 22 on turn) If we are getting 46.5 - 97 (or 0.48 - 1) on our bluff, then villain must fold ~67.6% for us to breakeven. Since you can't know if you are going to flop a straight draw or not, you can't really look at that preflop decision point. I'll just look at the turn decision point and hopefully that will be helpful. On the turn, after villain has bet, the pot is 64.5bb's. We are risking 79bb's to try to win the pot, however, now when called we will win 121.5bb's 25% of the time (64.5 in pot + 57 villain calls) Now, when villain calls our EV is (.25)(121.5) - (.75)(79) = -28.88bb's So when villain folds we win 64.5bb's, and when he calls we lose 28.9bb's on avg. So we are effectively getting 64.5 - 28.9 or 2.23 - 1 on our bluff on the turn. So villain must fold 31% for us to breakeven.
