This is a live 1/3 hand at Aria. I've been at the table for about 90 minutes and have been playing pretty tight. UTG+1 hasn't been there long, seems tight - he's limped a few pots and then gotten out on the flop. MP2 is very loose and aggressive. He doesn't tend to take pot size into account when he bets and so most of his bets are in the $20-$40 range regardless of what's in the pot. He's also shown me his cards almost every hand and so I know his calling range for a pf raise is any face card, Ax, connectors down to 42o. He'll 3bet with any pair.

I would bet turn again and probably c/f river. He'll call another bet with Qx. If river was anything but a Q or K, I'd value bet river small as well.

Why this line? U insta put him on a 9 after he flat ur flop bet? Why all this checking?I valuebet turn and river tbh and expect villain to call Qx.
Does he bet draws?only draw completed on river is JT.
K is a good river if he has KQ.

bet the turn obv

bet the turn and bet the river
