The villain was playing normal nothing like a crazy guy. In the moment when he gave me this raise I was confident that he was strong. The board was dry and no draws, and A was a lot in my range. He could easily check on flop with a set. I can't call to see him with a better hand and accept and say that was a cooler (And it was a 3 handed pot, shoe even more strenght), so what is your thoughts ? this kind of things happens a lot when I 3bet preflop the board is dry, I bet the flop the villain call, I bet the turn and the villain goes check/raise, is always a set, beating my AA. The bad thing was the pot was big and my stack small on river.

pre: i would go 200-225
flop: i rather randomize my cbeting frequency with some backdoors and check every other combo. For example, you have 12combos of AKo and 4 combos of AKs on this flop. In a 3way pot (with the flat caller behind whos range is med pair heavy IMO) i wouldnt cbet with 100% freq. I think you can check all ur 12 offsuit combos with very little FE vs the BU and cbet 30% pot with 3 suited combos with backdoors.
In HU pot i obv cbet my whole range.
DIDNT SEE YOU SKIP CBET - GG.
OTT I go broke vs unk, because population on this stakes is going crazy with Ax more often then they should
OTR 6x is perfect for you because it cuts down his set combos. CALL
Calling the turn just to fold the river is a big mistake here. You need to make a decision OTT whether you call or fold. If you call turn and fold this river you just burn money in the longrun. If you call only to hit A or a K, then it is not logical with your read that villain is set heavy. A or K doesnt improve your range here if hes sitting with a set.
Furthermore, if he had a full house OTR dont you think he would rip it in? His sizing makes me think that hes Ax heavy in this spot. Additionally, you are getting ridic price. Just call dude (or fold turn)

This is a ok flop to check on specially 3 handed. The turn id either raise or flat and commit to any river obv. Just so much garbage people will show up with

Yeah, not folding this river. There's plenty we can beat here and we're getting a good price.

I'd c-bet flop. Yes we are multi-way but that also makes it less likely we get floated with the random overs that make up a large part of their range.

As played call the river, which given the action so far is functionally a blank (nobody should really have a 6 unless it was A6 that was crushing already)
