Have you been raising alot of a-high flops? If you have he'll probably figure you're bluffing and may be 3-betting you w just two overs or something. If not, you're probably beat and can fold the turn. Tough situation. I think you went wrong when you check-raised the flop. I like check-calling and then re-evaluating on the turn with a decent chance of calling him down unless another big card comes up, although I wouldn't necessarily fold then either. The problem with c/ring this flop is that it sounds like he is the type of player who will be 3-betting you alot here and will have you beat or be drawing very live often.
