I think this is an interesting spot, because villain is a 13/10 nit. I check turn, because I am sure that he will fold anything I beat. I suspect he has a pocket pair here almost always and I expect him to try to get to showdown cheaply if he hadn't hit a set (I'm not 100% sure he'd take a passive line, though).
Do I want to fold here?
