[Popped Rod]

Yuck, I'd be inclined to muck this but it might be profitable to call and see the turn given you have position.

If he was as aggro as you make out, I would think he would have popped it PF with ATC (SB vs BB). But that bet makes me think he got a piece of it, possibly flush draw too and want to see where he's at.

If he checks the turn, you check behind and re-evaluate on the river.

If he bets the turn and you don't improve, up to you to fold or play poker.
