PF: Fold it. What are you even doing here?
Flop: Personaaly I'd bet right out and try to take it down right now witha big bet. OK, you decided the go for the check raise given that he would probably continuation bet. Not bad.
Turn: Having missed the check raise, you need to define your hand. You can bet out and represent that A. If he calls or raises you know your beat and can safely fold. By checking you have no idea of whether or not you are ahead. What are you going to do? Call to the river? Fold the best hand? You just dont know. Try betting next time. By checking twice you are inducing a bet. I'd bet here with nada. Find a way to make your decisions easier.
