This is probably high on my flatting range but it doesn't have that good playability on most situations. When the players behind are very aggressive I like 3betting more but as played I'd fold. Tyler's last video talks about equity realisation on some spots, that may be useful to you think deeper the spot.

Yeah 3b for sure, as played you just have to fold.

I think you played the hand fine. I am prone to flat in your situation, because you are most often going to play this 3 handed in posistion, with the BB and the HJ.
When the SB raises I fold as you did, as you will be in some crappy spots postflop.
Flatting IMO is the worst option.
If you have seen the SB do this often, or know him to be very aggressive, you can 4-bet jam on him and have a decent ammount of fold equity.

3 betting linear live is really good. I mean you say youself no-one folds to 3bets live, so you get peeled by Q9s+ and KTs and a lot of people (incorrectly?) 4 bet AQ so your in position with a dominating hand.

What Sam said above, plus not to mention that you're going to take the pot down a bunch when both you miss post flop (given that you have the initiative and position). Especially if he is of similar stack size to you - tough to float you out of position.

You're right that sometimes you'll face a 4bet bluff, but mostly a 4bet will be a hand that dominates you. You mentioned that a lot of 3bets were getting peeled anyway (so no 4bet), which doesnt suprise me too much live. Against a wide 3bet calling range KQ is going to be doing well. Plus you have the advantage of being the aggressor in position post flop.

That being said, a lot is going to be based on your perceived image too. If you'd been 3betting a lot, a call may be the better play. Also you have to think about the likelyhood of getting squeezed by aggro players acting after you, as in your case. As Raphael Nogueira mentioned, he prefers the 3bet in this case.

As the hand played out Im not sure whether I would call the SB's 3bet. Im guessing eff stack sizes are about 40bb. I m not sure I would be 4bet jamming that often. If you call I think youre going to be facing a flop cb the majority of the time, so its really going to down to how comfortable you feel you can play the hand post flop vs SB.

5b, i mostly agree w u. i flat all day here v the initial raise. 3b is cool cause he might fold a lot of Ax hands/small pairs because of a playability disadvantage oop. flatting is cool because of the stuff you said- he's wide, we're in position, we don't reopen, etc. and we probably have hands that benefit more by 3b that don't play as well as flats.

flatting the squeeze doesn't seem terrible to me. i haven't done any rigorous work. we're getting almost 3:1 and we'd be playing flop at a SPR of ~2, so it seems hard for us to mess it up too terribly post.

it'd be great if you knew how sb thinks about this spot. i'd have a tighter squeezing range here because of the spottiness (i think its an obvious-looking spot, so i'd expect them to defend wider both by flatting and 4b). and i'm more willing to flat some hands that others 3b (for better or worse). so i might be the guy you should consider folding against.

against someone who doesn't have a flatting range and thinks this is a good spot to 3b bluff, it seems like calling is better than folding. and whether calling is better than 4b would depend on stuff.

Why sizings are so different in live tournaments compared to online? Same game, but ppl seem to have very different strategies. What's up with that shit?
