I call the 3bet. He's going to bet the turn no matter what it is, and when we're ahead we don't mind that. Capping the flop here makes the hand tougher i think- are you folding/calling/raising if he leads the turn? what about a c/r? If he 3bets w/ AK, AQ, KQ, etc. He's leading the turn for sure. Also I might be able to find a fold somewhere- what's his post flop AF?
