How has he been playing? I'm not sure of his style or how often he's leading out a flop when he called a raise PF as it is usually either something players do a lot or never.

Now, we have 1200 in the pot PF and he leads out 1/2 pot. You have 6k left at this point. With the flush draw, gut shot draw, and an over I think you have plenty of outs even if you're behind right here.

A lot of people will want to call this and see a turn card, but if you completely miss the turn what do you do when he fires a 2nd barrel? Fold?

My play on this is raise to 2k-ish. If all goes well he folds right here and we take down a sizable pot. If he calls we wait and see what the turn brings and play it from there.

I can see this as him just leading out a flop that has a lot of potential scares to you and trying to take it down. He's going to be folding to a raise a lot of the time here IMO. Calling the flop looks like either a monster or a monster draw. I do not think you get paid off on a straight or flush here if it hits on the turn with you calling on the flop.
