[9cao]

I dont know Villain but have you been aggressive enough to warrant not raising a set on that board until the turn? Does Villain often not raise his sets on the flop? Have you been so aggressive that he would think AJ-AQ is way ahead here?

I think if he could call with a set on the flop and at least moderately respects your raises then it is a clear fold. Otherwise, I think you could call turn and make a river decision but you would have to think that he is going to fire at least 2/3 of pot here unless it is an ace or a heart which will either improve his hand or slow him down....um, actually just fold.
