I've been playing villian a lot latley HU. He's not horrible, but he moments of impatience and lapses in judgement where he makes very poor plays. So far he has been playing well. He opens from the SB for 300, i call with A2s.

Flop is 27Kr, and it goes check check. The turn is an offsuit Ace. I lead for 350, he makes 800, what is your play and why?
