KK UTG short handed.

[Duke]

10-20 with a half kill, but it's not currently a kill pot. Lineup is me and a bunch of old guys. Real old guys. It's 5 handed at the moment. I think they figured out that I had shifted gears.

I openraise UTG with KK, and get called by the cutoff and the button. The blinds fold.

Flop: K43r.

I bet, and they both call.

The turn is the Ace of rainbow. I check. CO bets, button raises, and I 3-bet. They both call.

River is a J. I bet. CO calls, button raises. I 3-bet. CO folds. Button 4-bets. I just call.

Comments? I'm thinking most about the decision to 3-bet the river, and the decision to check-raise the turn.
