[Absolution]

So the CO seems reasonable, he caps pre-flop and then 3-bets the flop to a check-raise. I really don't think you're getting bluffed on the turn so my instinct is to bet fold. I rarely say that in a pot this big, but I don't see him raising TT, JJ or AQ on the turn if we keep betting. I agree with Oink that checking and calling just throws away at least a BB, whereas if we bet and he calls we have an easy value bet on the river. The only problem with this is that he might be overaggressive and overplay AA on the turn, but that's 1 combo.
