Wow how many hands do you have on him for the 2%Pfr. I dont like the way you play it tho, unless the flop is REALLY bad, Id try to get my money in the middle. You play to hit a set, and when ou do, your not attacking with it?
Lead out for half pot on flop

That is a great flop for you to raise there. He isn't going to have a flush on the turn unless he raised with QJh or worse, and the only hands beating you are AA and KK. The turn is the ugly part of the hand for me. I'm thinking that he probably has and is trying to see a cheap river. You have to raise it up there without a doubt to protect your hand and make him pay for his draw.

So, in all, bet the flop first. Always bet your sets. Barring that, bet the turn second(or CR, since that seemed to be your plan, but you didn't go through with it). Please, just bet or raise SOMEWHERE. I can't imagine your hand not being good. His actions scream weakness at every street.

BTW, I don't see how important his PFR % is without the other stats like VPIP, hands played against him, AF. I feel like I'm in a boar without oars.
