I played this hand in a tournament on absolute poker. I'm "DENOUEMENT." I'm not sure if i made the correct decision in calling "HITTHATFLUSH"'s all-in raise after the turn card came up. He had been stealing a lot of pots with wild bluffs, occasionally going all-in with crap hands and getting extremely lucky draws to straights and flush. After the flop came down on this particular hand everyone checked to me and I bet with my pair of kings (normally I wouldn't but the players at the table didn't seem to fond of check raising). Then the turn came and HITTHATFLUSH goes all in. I knew he wasn't slowplaying three queens because, well frankly, slowplaying his good hands wasn't his style and he had been pushing all in quite frequently with nothing. I knew he might've been on a flush draw, so I called. Everyone else folds and on the river another heart comes up and he makes his flush. I can't see how I misplayed this hand except for one reason--knowing that he was on a flush draw, and knowing that he had 4X the amount of chips I did and that I'd be knocked out if he hit his flush but he wouldn't be knocked out if he didn't, was I wrong in taking the risk? Was he right to push all-in because of this, and was I wrong to call? Any information would be greatly appreciated. Here it is:
