Please help me understand this math problem

Right but the 66% refers to the times when you raise and always get 3-bet when beat. I don't know if this hand applies (haven't read it) but it doesn't in many cases. Like if you estimate that you will get 3-bet just 50% of the time time you are beat (assume you always call it) then you need 60% equity to raise.

The 66.6% rule is good in situations where you have a strong hand and the other guy may or may not have outdrawn you. Say you flop a set and bet the flop and turn. Now a 3rd [img]/images/graemlins/diamond.gif[/img] hits on the river and your opponent bets. He is almost certainly going to 3-bet a flush (and call if he made 2-pair or something) so you need to be good 2/3 of the time to raise. There are other cases where you don't need anywhere near that much equity to get a value raise in.
