Overpair Fold Check - $50NL

[kurto]

Villain was Peepleschamp. His stats were something like 20/5/1... He was a very quiet opponent. Certainly haven't seen him get out of line. More importantly his %of hands that went to showdown was 30% and his won at showdown was 83% (5 out of 6)

I have $87.60 on the button.
peepleschamp has $92.85 UTG.

peep limps UTG.
I raise it to $3 from the button with KK
peep calls. Everyone else folds.
