Default Re: Probability: Three-flush to Flush

On a poker note, you can't call a bet on the flop getting 23:1 if you have only a runner runner flush draw. That's (mostly) because you'll also have to pay a double size bet on 4th street to draw at your hand on the river. Sklansky went through this calculation in depth in one of his lesser read books (maybe PGL??) and determined that you need something like 28:1, I don't really remember. But backdoor draws can add value to a hand that has some to begin with, sometimes swinging a fold to a call. See TOP for a great discussion of this. A classic example in HE is overcards on the flop that also have a 3 flush and 3 straight. (Note that drawing at a flush/straight on 4th street will also allow you to often catch an winning pair you wouldn't have otherwise.)
