Also, let's ponder this for a sec. That last reraise by villain smells of a slow-played hand. He may just be stupid, but more likely some sort of slow play. Why? Because the 9h could not have helped him. It did not complete a flush or straight draw.

So, what could he be slowplaying here? KK is a possibility (but unlikely because of the preflop limp). Also the wheel straight is a possibility. Both hands have you beat. He may also have an AK, but his betting wouldn't make much sense for that hand for the same reason as the KK (preflop limp). Because it seems he's slowplaying the flopped wheel, you gotta check.
