Villain seems to be some kind of reg, I've seen him around. His stats might seem somewhat standard but I have a pretty solid feeling that he's a NIT. I wouldn't be surprised at all if he only 4b like QQ+ and AK here, but then again I don't know that.

So how would you play this hand? Do I have to call flop? I would probably just fold JJ vs 50% pot OTF but against this size I figured perhaps I should call.
