I think this is definately aces if the CO is a really tight passive player that only reraises with AA or KK. If he is loose and scrappy at all, then you probably should have called.

I like the fold here. You had a read on the player, and you trusted yourself. Good work.

I know many players that will never ever reraise with anything but AA or KK, this is an observation you have to make without pokertracker. If he is one of them I think you can be confident with your fold. Against just about anyone else this is a bad fold.
