AA - to fold or not to fold?

[NNH]

I can't get my hand history from work, so I'm going off my recollection of the hand.

This is a $20 on Party. Level 2 blinds. 9 players left.

Hero has AA on the button. 3 limpers, I make it 3x to 90. SB calls, MP calls, CO calls.

Flop is Q[img]/images/graemlins/spade.gif[/img] 6[img]/images/graemlins/spade.gif[/img] 8[img]/images/graemlins/diamond.gif[/img]. SB makes it 100. Folds around to CO who makes it 200. I reraise all-in and get called by both villains.

Looking back at the hand, this should be an easy fold right? I had SB on top pair as he seemed like a weak player, but really had no read on CO. Again it was early on in the tourney.

How was my line? Results to come.
