Looks fine. I mean, you're probably running into quads or a bigger pair, but against a semi-retarded opponent, I think you've got to call down.

Nice hand. You definately got to pull back, especially since he raised preflop. If he has something like ace high he's probablly not going anywhere, but it's far more likely that he has a higher pocket pair.
