Well, with his stats his range preflop is probably 99+ and AK. The fact that he didn't repop pre leads me think AA is less likely than the rest. Calling is going to accomplish nothing and you will still be committed to the pot. Villain is also somewhat aggro post flop. I think I shove but hate myself when he shows me his set of J's.
