PFR has a VP$IP of 25%, but a PFR of 4% of 1200 hands. he used up his entire time on the river and told me he folded because he thought i rivered him with QQ.

SB is unknown and my only real fear on the turn. i should have bet larger - in the realm of 150 i think.

also, who reraises the flop?

I would have reraised. Because I wouldn't want to get busted by some whack straight draw the SB might have, and it's so hard for MP2 to fold AA or KK (which he's representing.).

That being said...it's certainly not a horrible play or anything. When I went over it, It didn't really bother me.

MP2 made a great check on the turn.

I think you played it perfectly. The only change I might make would be that I might not push the river.

If he really had AA or KK which Im not so sure of, hes not going to call that much on the river if he wasnt willing to bet the turn and only called your turn bet.

I think another $100 on the river is better.
