I have a set, check/fold?

[KdoubleK]

Live 20-40. I open UTG with KK, passes around to button who 3 bets, BB on raging tilt goes all in for 15 chips total, button and I call and we're heads up for the flop. A little background, button knows I generally play very solid but he's seen me make one or two goofy plays. I know he plays solid but I've seen him do the same. We've never made strange plays against each other though. Flop comes A [img]/images/graemlins/club.gif[/img]K [img]/images/graemlins/spade.gif[/img]3 [img]/images/graemlins/club.gif[/img]. I check, he bets, I raise, he 3 bets, I 4 bet, he 5 bets, I 6 bet, he 7 bets, I pause for a sec and 8 bet, he insta-9 bets, I puke and go into check call mode. Turn is 6 [img]/images/graemlins/diamond.gif[/img]. I check call. River is blank and as I check BB mucks K [img]/images/graemlins/club.gif[/img]10 [img]/images/graemlins/club.gif[/img] face up in disgust. Big pot, muck a set for 1 more?
