Overpair against crazy villain

[Village Idiot]

Him doing something out of character like that is scary.
It ususally measn he has you crushed.
Or he has 15 outs or better IMO.

If he has a gut shot and the flush draw he's ahead of you.
If he has 1 over and the flush draw then it's a good call.

Meh. I fold and wait for a better spot.
