Folding AA (Full Tilt 3/6)

First time poster, long time lurker. Sorry for the lack of conversion, but Full Tilt isnt supported by the converter. Anyways...

Hero is UTG with AsAd
Button is 41.26/6.90/1.76 after 812 hands
BB is 18.97/8.84/1.94 after 701 hands
(I heart PT)

Preflop - Hero raises, folds Button who calls, SB folds, BB calls.

Flop Qc 2s Jc - Hero bets, Button calls, BB calls

Turn Kd - BB checks, Hero bets, Button raises, BB 3-bets (WTF did i just walk into), Hero folds

River 8d - BB bets, Button calls

Results - BB shows 9hTh (Straight K-high), Button mucks AhAc (Pair of Aces)

I folded the turn thinking at least one of them had 2 paint, but I didnt see the other rockets or the 9Ts coming at any point.

Granted that I folded when I didnt have the best hand anymore, but did I misplay this or did I just run into something and got out at right time?
