Stack Sizes could be helpful.

I don't like that raise at all.
There is a slight chance that he's minraising with a medium pocket pair, or even air. Then he definitely folds to that raise.

AQ or a set are much more likely, and you're giving away a lot of money to these hands.

If you think he's capable of playing that way with anything that you beat, then I would just call his minraise.
