[Warbuff]

I'm not as experienced as many of the posters here and maybe this is a bit of a stretch but after 100 hands does the Villain have a strong enough read on you? Perhaps he thinks he can push you off the hand.

I think its important to note that the Villain has 58.65 left after his bet, essentially he's pot committed. Maybe he was unable to put you on a set of 2's and is over betting for value. I'd argue he has an over pair to the board and take my chances putting him all in...
