I agree that AA should have folded on the Flop in most cases in Rush&cash games. Against some players it might be +ev call but you know how tight the game is in general in rush&cash games. The most common tactic for many is just to fish sets from flops and turns and then shove them all in.
You hold A
so it's not going to be nut flush draw hands. Maybe K
Q
otherwise villain's line stinks of sets
And often even if your opponent had a draw after that action, they would probably just call out of position.
