4 flush on board, I have the K, it's 2 bets to me.

PF: I raise UTG with A [img]/images/graemlins/heart.gif[/img] K [img]/images/graemlins/club.gif[/img]. 4 players call, the blinds fold.

Flop: 2 [img]/images/graemlins/club.gif[/img], 7 [img]/images/graemlins/club.gif[/img], 9 [img]/images/graemlins/diamond.gif[/img]. Everyone checks.

Turn: 3 [img]/images/graemlins/club.gif[/img]. I bet, 2 folds, CO and button call.

River: T [img]/images/graemlins/club.gif[/img]. I bet, CO raises, button 3 bets.

Button is a total fish, who would 3 bet with any club. I'm more concerned with the CO, who I have no read on. I myself wouldn't raise there with anything but the ace, but then again, I see lots of players do it. Can I be sure enough that the ace is out to fold?
