even tho they both hit their 1 outers, you were not that far behind either one of them...my guess is the guy that thought about calling preflop had the KKxx, and he still made an ok call...on the flop you were about a 40% dog....not in too bad of shape, guy with KK is dead...seeing as you hold his last remaining shot at beating trip aces...so think about it this way...your getting just over 2.5 times your money and your almost even...almost you made the right play but i think it could have been folded preflop, think about if you folded preflop, AA and KK both hit sets, one of them is going home in this hand and you move up the money!
