AA turn fold in big pot for one bet, 15/30

[billyjex]

Online 15/30 5-handed. CO is loose and bad. Cold calls PF alot, seems to chase. No read on SB, he is new to the table. Sorry stat geeks, I don't use pokerace.

I am dealt black AA utg and raise. CO calls, SB calls, BB calls.

Flop is Td 2d 7h. Checked to me, I bet, CO insta calls, SB calls, BB folds.

Turn is 6d. Check, I bet, CO calls, SB raises, I fold.

Turn was a scare card, SB c/r's both of us, and CO doesn't look like he's going anywhere. Pot was huge, though. Good fold?

I'd call this down against unknowns, they have no reason to think you've got better than AK or some crap pair. Against certain opponents this is an easy fold though.
