Big PP vs a PF CR and an accidental check

[hightiger]

Playing 10 handed at the Borgata, 1/2 NL.

I'm interested in how you would play this hand post flop. Villain appears to be a solid player, is not loose nor extremely tight.

Villain is sitting in mid position with $500, Hero is on the button holding K [img]/images/graemlins/heart.gif[/img] K [img]/images/graemlins/club.gif[/img] with $250.

Villain limps, Hero bets $10, everyone folds around to the Villain who reraises to $50, Hero calls.

Pot: $103
Flop: Q [img]/images/graemlins/club.gif[/img] 9 [img]/images/graemlins/heart.gif[/img] 5 [img]/images/graemlins/diamond.gif[/img]

Villain absent mindedly taps the table while thinking and accidentally commits himself to checking, despite his clear desire to bet. Hero?
