Nah he's right not to raise here I think IP. If he doesn't raise flop I think I'd call down, or bet the river if checked to so he gets to decide if money goes in and can't miss a street of value by not raising.

I think if he called the turn how does the 3 change anything? You ran into a set here but when can he have that calls two streets and fold the river? After getting 3bet from UTG his range is like QQ-77, AK, AJs+ maybe. Nothing in that that calls flop and turn gives up on that river IMO.

I wouldn't try and bluff vs the tight range this guy calls with UTG anyway.

If villain is bad then I don't mind the 3 bet for value if he's calling with worse.

I can't see if there's a flush draw on the flop but it's a board texture I would check and give up on as we're 3 betting because he's loose and will call with dominated Ax, but he also has a ton of everything which is never folding on this board.

As played the turn barrel on the K is probably ok but I'm giving up on the river.

Try formatting your hands on Weaktight so we can see clearer.

I'm not a huge fan of making the play on this texture. Unless you have a very specific reason to go aggressive I'd just play this passively.

I would check back flop and bet turn if he checked / call turn if he led. Flop is bad for you in terms of his raise calling range. He should play reasonably face up turn to river if you check back the flop.

Main points here are that you mentioned you are triple barrelling to fold out small pairs and draw that have missed, there’s not that many draws villain can have on this board (unless there were flush draws on board that missed, suits were left out of HH) and it’s pretty unlikely villain can have small pairs after calling your double barrel.

Preflop: You can definitely consider calling here to keep all of villains dominated Ax in the hand but I don’t mind the 3bet either. I would recommend making the 3bet larger though since you are OOP.

Flop: I don’t like c-betting here. The board is very well connected and I doubt your bet is getting through here often enough to be turning a profit.

Turn: As played I like the double barrel for sure. You put a huge amount of pressure on all of his single pair hands here and I would expect to get quite a lot of folds with this line here, plus you have some outs to the nuts for when you do get called.

River: I really don’t like the triple barrel here. Villain has called twice here on a scary board and the river is the brickiest brick that ever did brick. It has changed nothing so the majority of villains turn calling range will likely be calling you down on the river.
