Totally agree with everything said here, the river is a definite check behind rather than turning it into the bluff as I did but I do still think that AKo could be in his range that would two barrel and then check the river when the flush hits.

I'm thinking that raising the flop may have been the best play though...I have an over-pair to the board and my line looks like a pp that is either an overpair or a set, if he has AK/Q then he's likely to just call and shutdown on a black turn and then I know where I'm at and if he has a set or an overpair he's likely to play back at me and I can get away at that point.

Thoughts?
