[BHold]

Tough spot. He knows you don't have a set or flush as you would have pushed flop with FD and either pushed flop or turn with set yes? He basically knows you have 99-QQ the majority of the time here. He also can't have the flush as the turn K is a card he would have to push on with that.

Despite this I still think it's more likely that he has ak/aa and I would fold.

Edit: shouldn't just say ak/aa, i think this is aa/ak/kq/qq very often
