Wow that's tough. Even if you pushed harder on the flop I think he still would have made that bluff on the turn. (unless you go all-in of course)

If he really had it I think he would've gone for a check-raise. And we know that he's capable of that play because he used it on the flop. He also overbet the pot on the turn. Then again if he's a crafty player he might be trying to send misinformation to make you think that he wants to get paid off. I think I wuold folded like you.

I think in general it's best to avoid tricky players. No PFR with AA, a check-raise on the flop, big bluff on the turn. This guy would make me go insane.
