So the pot's 600 on the flop, he bets 450 on the flop, you have 1960 left. I assume you don't have the AhKh. I think I call and see what he does on the turn. This sure feels like AT or AQ to me, so if he bets out big again on the turn, I think we can let this go. I don't like raising since you basically have to jam to make it worthwhile, and folding seems a bit weak, although given your read on him, I don't hate it. If he's really weak-passive, though, there are a lot of cards that will slow him down on the turn, so I'd try to get to a cheap showdown.
