So you and CoachK25 were in the
same hand, eh? If so, you guys have the details a bit different.
So if we assume (oddly) that SB is always calling, your math is correct, but it's still a fold. Why? One because your 32% chance to hit a straight is just an estimate. It is actually 31.5%. But that's still < 31.27%, I hear you cry. Yes. But you don't always win when you hit the straight. Sometimes someone else has the same hand and you chop, and sometimes you get counterfeited by a full-house. If we give one of them an overpair, one 2-pair, and one a set, for example, you're only at about 27.5% equity.
