yea but what's wrong with checking to the turn? i agree with folding the turn but i don't see how you question checking the flop behind if we think he has bare aces.
any 4, 5, 6, 8 gives us what's likely to be the best hand, any 3, 7 or
gives us more outs.
otherwise i have to agree 100% with Doorbread, somehow just looks like he hit the flop bigtime. wouldn't he just be shoving naked aces with around 1 PSB left? smells super fishy imo, i'm thinking AAJJ or AA22.
