AKo - TPTK
We all now this standard line with AK, and it's effectiveness has been proven time and time again.
How about this, you have AK PF and raise, BB calls. Flop comes a A92r and when checked to you bet. BB calls. Turn is a blank and BB checks. You check behind. Then the river is a K, giving you top two pair. Do you still just call if BB bets, or do you raise?
