(FR) AQo - TPTK in 3-bet pot

Preflop: AQo I agree with you that has a good equity related to MP whole range, but, when he flat calls your squeeze I supposed he folded a big part of his range and keep just hands with excellent equity.
SB calls was a complicated point as he probrably narrowed down his range of cold call.

Flop: This board texture is complicated in a multiway pot, should bet 1/2 pot was ok because of texture. There are a bunch of outs that could help villains range.

OTT: What ranges SB villain will keep calling you? 88-AA and draws - because of that barreling is mandatory or you were way behind or way ahead.

In 3bet pots iam cbetting between 1/3 and 1/2 pot. We hit a solid flop and should have the best hand very often. In multiway pots iam cbetting almost always for value with at least TPTK or hands with good implieds. In this case, considering villains stack, i would have bet exactly those 28 BB.

Against a bigger stack the hand is done OTT if he bets.

In 3bet spots the cbet should be accordingly board texture and how much equity do you have + fold equity.
We bet for 2 reasons:
Value
Bluff
and collect dead Money is connected with one of 2's

I’m not totally happy with the squeeze. As BTN after MP+2 raising and CO calling ... ok. But it is MP who is raising, and i tend to give him a bit more credit. After his call, he has a premium pair, a premium A or KQ. JJ, TT, AQ, AJs, KQs. SB can have anything like small pairs, sc, Axs.

OTF, you have TPTK, MP is no problem, he defintely has no big draw on this board. He has a better pair or a set (TT), or he has not. The only draw is AJ. And he might have a worse TP. wa/wb. BUT ... SB can have a straight, 88, an OESD, a gutshot with or without a pair ... you cannot know. But since there are a lot of draws possible, you have to protect. Even in a big pot, on that wet board and against two opponents, i would bet higher than 1/2. And looking at the stack of SB, i would set him all-in.

OTT, you are toast. But as you say ... 7BB in a 82 bb (+7 bb from his call) ... pot odds are too good. You have to win once in 13 hands. And occassionally, you will see 87s and no 6 otr.
