B&M 3/6: KK overpair, lots of action HU

[KingFelix34]

live 3/6, deck has been hitting me in the face and I am up about $350. Villain is the tightest player at the table and is the definition of an ABC poker nit.

Hero on the button: K[img]/images/graemlins/diamond.gif[/img] K[img]/images/graemlins/spade.gif[/img]

Pre-flop: Villain is UTG and raises, MP2 calls, Hero 3-bets, SB/BB fold, Villain Caps, MP2 calls, Hero Calls.

Flop (13 SB): T[img]/images/graemlins/heart.gif[/img], 3[img]/images/graemlins/spade.gif[/img], 6[img]/images/graemlins/diamond.gif[/img]
Villain bets, MP2 calls, Hero Raises, Villain 3-bets, MP2 folds, Hero Caps, Villain calls.

Turn (10.5 BB): Q [img]/images/graemlins/spade.gif[/img]

Villain Bets, Hero?

I was about 50/50 for folding/calling here.
