bet $18 on turn then you dont care what the river is as your priced in.

Im not sure here, what is he calling all streets with that you beat? pocket pairs only TT, i doubt he would call down with any other lower PP other than 88 for the OESD. My thought process would be he doesent have a higher PP because he wouldnt have limped in from the button with AA-QQ in a multiway pot, would he really call 2 bets with AK-AJ KQ then make a river suck bet with air? do players at .50 make these sort of plays?

2% PFR over 45 hands really isent a big enough sample size to say he never raises anything.

Unless this guy is a total station and calls down with any PP id have to say your behind much more than your ahead. If hes hit any part of the bord except the 6 your dead here. Tough decision.. I think i may have folded too.

check the turn. you dont have that great of a hand here so try to keep it smaller. that will also get hands like 9x and some PPs you have beat to think they are better than they are.
if you do bet, bet more like miffed said.
