Fold or Push?

SB is extremely LAG. He already rivered me with a Q6o against my JJ when he wasn't in the blinds.

My read was he had an Ax. What do you guys think I should have done?

I would fold here. Looks like a set or something like AsKs for a pretty huge draw.

oops..didn't read what you wrote on the top /images/graemlins/blush.gif . That changes things a lot. In that case, I think calling is fine. From the looks of it, a lone ace seems like a good read. Would he do this with something like A5?

Normally I'd fold but based on your read I'd push, glad you caught your set but I hope SB didn't have 64 or flush draw.
