Villain had been very active playing almost every hand, raising frequently. Calls down light but usually has a good hand when showing aggression post flop. Hero has been mostly TAG but villain probably not paying attention.

Hero raises to 12 with AA after 1 EP limper, villain raises to 24, folds to hero who raises to 80. Villain calls.(pot 159)

Flop K J 4 rainbow. Villain shoves for 240. Hero?

What is villain's 3bet range? And likewise, what is his 4bet calling range? Do you have history with him? Is he a donk/competent/fish/LAG fish/TAG?

There is one hand I would generally place in this villain's 3bet/4bet calling range that nailed this flop: JJ. AKs is another possibility. I would remove KK from his range as he would have jammed preflop given the action. So you are either way ahead or way behind here.

Snap call.

We are exactly 50/50 vs KK, JJ, and AK.

Call.

You have the initiative, and V likely recognizes this, as it's just somewhat of a 'natural' inclination to check to the raiser. If he is unobservant as you believe, but recognizes your initiative, a bet from him would spike my bluff-o-meter. Why would he bet if you have the initiative, and are likely to bet yourself?

Risking 240 to win 400 you need to be good 37.5%, furthermore, you're not dead if you're behind.

Its tough and highly read dependent, but I'd likely make a crying call given the information and expect to see KQ, KJ, QT, QJ, AK.

Not exactly happy but call. Once you raise to 80 and get called your pot committed vs villain on all but the worst flops and this isn't quite bad enough when villain shoves into you. You can only fold here if you know villain is only shoving two pair+ for fear you could draw out and never has AK- or a draw.

Very difficult to lay down here intuitively and mathematically. The way you describe him he even could be on AQ. Definite call.

Thanks for all your thoughts. I called fairly quickly and villain had KK for top set.

I'm laughing at the super tight ranges some of us are putting this villian on. The above comments are more accurate for a villian playing 'most hands' IMO.

Sure he can have AK and JJ but I think he can also have QQ, AA, and a whole lot more. As described I think villian can have any suited kx, Jx suited with AJ or QJ more likely, he can have 2big cards like KJ or KQ, and he probably has a whole bunch of trash like suited aces and suited connectors that he called with pre flop and whiffed with.

I really don't see how we can fold here. If villian has AA beat why would he not check raise? I think the shove is either frustration shove cuz he missed the flop or he flopped a strong draw / pair with a draw and is semi-bluffing. Call all day and in every way and when he flips over J4 or KJ for the win know that you made a pretty good losing call as you ranged villian correctly.

OK that is one hand I did not expect to see. I have not met a villian who plays most hands but does not get AI with KK pre flop. Perhaps villian sees you as super duper tight and thus put you on exactly AA with the 4 bet?

Guess i would have stacked off as well. Tough loss.

This is why I asked about reads o the opponent. A nit will call the 4 bet with KK preflop most of the time as the are afraid of AA or AK/AQ spiking the flop. However, thinking players/LAG/TAG will get it all in preflop in that scenario, so player type and their perception of you makes a world of difference.

Yeah I agree 100% my response was tailored to a villian who plays most hands. I personally have not run into many super loose villians who do not get AI with KK pre flop. The whole point of playing loose is to get big value on your good hands. I realize villain might not understand this but most LAG players get this concept even if it is on a subconscience level. They push bad hands, why the heck not push the good ones when they show up?

So I guess maybe I was too quick to make my read off the given information. Also the donk shove on the flop threw me off a bunch. I would expect a check raise from villian as described holding the current nuts.

You have his range crushed and an SPR low enough to stack off. This is a super snap call. If you lost there isn't much you could do once be puts in 1/3 p his stack pre I am never folding.
