AK gets 4 bet.

At this stack depth I don’t think you should flat, even IP.

Jam can’t be terrible given player description. But if on my A game I probably fold. UTG opening then 4-betting a perceived nit who 3-bet from UTG+1 is as strong as it gets. Usually AK/QQ+

Call AKs, fold off suit.

Fold, don’t think it’s close

just fold.

Biggest nit in the poker room 3bets villain's utg open and then comes back over the top? Yeah I prob just fold. At worst we're flipping. At best we're chopping.

FWIW, I don't think we should necessarily assume that our opponents see us the way we think they should see us. It's possible V hasn't noticed that you haven't entered a pot in recent memory.

If we think he has noticed, then your 5B jam should be seen as insanely strong, if it matters. He might fold QQ. I'd think we could jam or fold here, and the EV would be pretty close.

The fact that he quickly raised makes me think we should jam, and he'll fold a lot. If he had a strong hand, he'd have to take a moment to look at our stack, and think about whether or not he has any fold equity, and what size he should take with his raise.

V sounds like he's pretty LAG. And from the sound of it, he's winning? He might feel emboldened to torch $125 with a 4B here, if he's been on a heater and built a big stack, and will find the fold if we 5B jam.

Fold. Pipe dream to think this player would fold QQ. With no showdowns I would just assume he is tight and aggressive, 3b good pairs, good A high hands, good K high hands, etc, and has been getting good hands while at the table. Very few players at 1/3 have light 4b in their repertoire. The presumption should be that they don't light 4b until proven otherwise.

For those saying jam, did you bother giving v a 4b range and considering what villain is calling a jam with and working out the EV? Good chance it is JJ+ and AK, not folding, and vs that range AKo jamming is definitively losing. You would have to give him some 4bet folds like A5s, KJs, etc. Also a pipe dream. People do it, but it is rare enough we should assume they don't do it.

I fold AK to 4bets without some kind of special circumstance because my experience is that low stakes 4bets are extremely nutted.

I'm curious to know if others believe a fast 4bet is more likely weak or strong. If weak what does that mean, exactly? A GTO 4bet bluff? Or just JJ-QQ/Ak.

Anyway, I'm folding without prior evidence that Villain can execute and size a bluff of this kind.

Eh at 1/3 I assume most people can't even spell GTO and are just playing their own 2 cards, especially when acting quickly.

Not a great seat as we're going to be facing too many preflop raises next to act. I would prefer to sit on his right so I can limp/reraise, although I'd feel more comfortable at my typical shortstack of $200 than I would at $400 (where it is probably best to sit across the table from him).

As played, I think this is just a fold. A 4bet is already massively skewed to AA/KK, let alone against the room nit's EP 3bet.

probably a fold

I think the fast 4B is more likely to be weak than strong, at least in relative terms (relative to the usual 3B/4B ranges in a 1/3 game). But, it depends a lot on the player type, and if it's a 4B jam or a 4B size that would allow V to fold to a 5B jam.

Here, my reasoning is that V sounds fairly aggro and capable. He's been winning, often without a showdown, whereas hero has mostly been folding. A 4B to $125 might be 1/3 of this guy's profit on the session, but he's only been at the table 2 hours, and apparently he's been running good, or just running over the table. Whereas the $125 is a big bet to hero, it may be trivial to V.

At the risk of being shouted down by the crowd here, I wouldn't be overly concerned about V's range if we were to 5B jam with AK. We block AA/KK, and I'd expect V to fold most of, if not all of the rest of his range here, when we 5B jam, regardless of whether or not V noticed that hero's been mostly folding the past 2 hours.

If he calls with JJ-QQ/AK, so be it. It's a fair fight. It would be awesome if he calls with AQ, or folds JJ-QQ/AK. If he snaps us off with AA/KK, okay, that's poker.

Take it all with a grain of salt. I can be pretty LAG when I run up a big stack at 1/3. I may be reading too much into what V is doing here.

I'm confident enough that a 4bet of this size (2.75x) at 130bb should, as a default at these stakes, be treated as sign of strength. The relative speed of the 4bet can be a reason to adjust the default along with other factors (such as Villain catching a bit of a heater, as you suggest). Of course another common game-flow factor might be if Hero had been 3betting more than most, which in this case he wasn't. The "fast" 4bet shove is typically AK, if not a reverse tell by a canny reg with KK+.

On the other hand, I find a slow thoughtful 4bet to a similar 2.5x sizing can be a bluff (but also can be a rec Hollywooding indecision with AA). Regardless, 4bet spots are significant, so any extra information is helpful, especially when we're on the margins with JJ/QQ/AK.

Let's not forget how excited players are internally when they get dealt those "pocket rockets" and then are re-raised ... the overwhelming emotion/thought pattern is they want the money in the pot asap but also want to act a little cool and composed. Let's also not forget how scared some get with KK, often to extent of losing composure because the pot they "deserve" to win might be spoilt by an Axx flop. Both scenarios are ripe for live tells.

Fair enough.

I've 4B to this size at 1/3 with TT, AQ, and some other non-nut holdings, with a plan to fold if my opponents 5B jammed on me. I wouldn't necessarily read too much into the bet sizing.

Ordinarily I'd be hesitant to continue as hero. But the speed of V's raise, and the table dynamics are the factors which might lead me to suspect shenanigans, and respond in kind.

Folding is fine, against the population. If we're looking for reasons to find another course, I think we have some here.

I dunno about ppl who wanna readily burn $400 on A-high thinking V would make a poker move against Hero, who is self-professed nittiest in the room. It's a fold for me.
