Hero (BB) $200
Villain (SB) $900.
Villain is up big, but he does some wacky things. Earlier, he got raised on the flop. He flipped over his hand, exposing TT on Jxhxh board, and jammed all in saying he "thought his opponent had a flush draw." He's LAG, but not an idiot.

Hero ....
Villain is definitely capable of a bluff-jam with air. But I think this comes down to number of 3s in his range vs. A5, A4, A2 in his range. I suppose he could have a set, too.
