Villain is a reg, don't know much more about him.

Preflop: standard call here.

Flop: he bets a bit under B50 here, more than a typical range bet, though he is OOP. It is a very good board for my AQ, not sure how likely A3s/A2s/54s are.

Turn: A6s improved, but that's not a typical hand. 76s/65s are somehow possible.

River: if not for the FD or if I had at least one blocker on my hand, I would have snapped it. But here I lose to AK and to plenty of flushes, I also doubt he jams worse Ax here. Not sure what MDA says, but Axx boards don't seem to be bluffed as often as other ones like AKx, KTx, QTx, etc.

Call or fold?
