Blind battle, easy fold on the turn?

[Guido]

600NL 5 handed

It's folded to me in the SB with A [img]/images/graemlins/heart.gif[/img] 8 [img]/images/graemlins/heart.gif[/img]. I have $821 and the BB covers. BB is pushing everybody around but isn't bad from what I've seen. Just very aggro both preflop and postflop.

I make it $22 and the BB 3-bets to $38, I call.

Flop comes: A [img]/images/graemlins/club.gif[/img] K [img]/images/graemlins/heart.gif[/img] J [img]/images/graemlins/club.gif[/img]

I check, should I bet about the pot?

He bets $75, I check-raise to $150. He calls.

Turn is 7 [img]/images/graemlins/heart.gif[/img].

I check, he bets $250. I fold.

Please let me know what you would do and why.

Thanks,

Guido
