[Leaky Game]

I agree with the others and think you're way ahead, but..

..only one poster addressed the real problem with this hand. You know he plays a lot of hands and you know he raises a lot of hands. You get a good PF hand in position, he auto-raises and you just call? The reason you're having a hard time putting him on a hand is because you didn't reraise here. He could be playing a big ace, small ace, middle pair, big pair....basically you have no idea because he pf raises a good deal of the time.

I would have reraised PF to something around $9, depending on what kind of bets he's been calling. Given your line though, I think I would have checked behind as well...but I certainly have leaks in my game.
