Who is villain? BB?

I don't like the raise on the river. On a board like this, a jack may give someone two pair or a straight. BB may be aggressive, but I doubt he is betting out on the turn without a "Q" again after all the action on the flop. I guess you can call on the river. I doubt BB is laying down his hand at this point, so you'd really have to have a clean read on him that he had air OR that he'd be wiling to lay down his mid pair. And that's if he doesn't have the Q. I'm laying this one down, most likely on the flop.
