yes I call, but i probably would have put a little in on the flop or the turn.

Bet 700 on the flop.
Bet 1450 on the turn. (suppossing he calls and checks)
Bet 3000 on the river. (suppossing he calls and checks)

If he raises any street, I call down. If he shoves at any point which he'll only do with an Ace to represent AQ, I'm calling. Blind on blind 56 is the nuts when you flop A55.

As this has played out, I think he has an Ace and think you're splitting, but can get you to fold in fear of A7 or AQ or he has AQ or A7. He has little reason to believe you have an Ace and none at all to believe you have a 5, though. Damn, this looks like A-rag.
