Had 350 hands on the guy but not many notes so they must have been playing solid. They tank checked both turn and river
Flop I just range 1/3 as 3bp IP PFR. I don't 3-bet flop IP unless it's a jam so easy call
Turn I would usually bet, they'll fold a lot and the XC range I'd guess is a lot of draws that won't bet river often unless they hit
River The line is VERY weak which would usually incentivize me to be very aggressive with thin value and bluffs. I really doubt Qx is calling when AK can't bluff, but it's 7-max 135bb deep so they should probably flat some AK and I could definitely see it taking this line and calling river.
Solver mixes turn and only (rarely) bets river with a heart, mixing vs jam
