bad beat or badly played?
on a 9 handed NLHE table I got dealt pocket KK's in MP. I raised 4xBB. CO and Button call, the rest are all folded. Flop 2d,8d,Qh. I raise 3/4th of pot. CO and Button Call. Turn card 3d. Out of position here I pushed with my remaining stack of 20BB's. Both CO and Button call. River Card As. CO shows AQ for two pair, Button shows 10d-7d for flush. Do I give somebody a flush with when that third diamond hits? I bet there so as not to give anyone a one card flush. I was going to lose with the KK's to the CO anyhow since he had top pair top kicker and he hit his ace on the river but I'd like to know a better way to play this hand.
