Interesting Hand Yesterday at the Bellagio 100-200 LH

[karpov]

Yesterday I played this hand: UTG is Patrik Antonius friend, Patrik was waiting behind him to go to eat, he looks great and relaxed after winning millions online and he is training for his $200.000 tennis match in January against Gus Hansen, so back to the hand. UTG raised, I'm UTG+1 and got A [img]/images/graemlins/club.gif[/img]A [img]/images/graemlins/spade.gif[/img] and 3bets, everybody folds to big fish in BB who calls. UTG 4B and I 5Bets, fish calls. Flop: 10 [img]/images/graemlins/spade.gif[/img] 7 [img]/images/graemlins/heart.gif[/img] 6 [img]/images/graemlins/spade.gif[/img]. UTG bets I 2b fish calls UTG 3b I 4b fish calls UTG 5b, call, call at that point I'm not thinking about KK but top set.
Turn 3 [img]/images/graemlins/spade.gif[/img] and now fish leads!, UTG call in disgust and I call with the nut flush draw.
River 2 [img]/images/graemlins/diamond.gif[/img] and fish bets again, UTG calls and I call.
Would you have play any different? Who do you think was the winner?
