Hero stack is at 3.2million
Villain at 2.9million
history with villain: Young Established local pro in Texas, very aggressive pre flop and has shown down some bluffs like a 3 bet squeeze with 106 off.

Blinds are 30/60k Big Bling ante

middle position raises to 140k Villain calls and Hero looks down at AQ We decide to three bet to 340k and middle position folds and Villain calls. Hero is on the cutoff and has position.

pot around 700k
Flop is QJ5 two hearts Villain checks and Hero bets 400k
Villain check raises to 1.4million and Hero calls.
Turn is 4 of clubs and Villain Jams all in
Hero has Villain covered by 200-300k
do we call or fold turn?
should I be checking Flop?

things to consider in hand if we call and are correct we take a massive chip lead in tourney and knock out one of the better players. If we fold we still have around 1.4million which puts us around 5 o 6 in chips with 14 left in tourney.

Flop pot should be over 900k, no? 10% ante would be 340k+340k+140k+30k+60k+ante=~916k

IDK you say V is a pro but is it good to go call-call pre OOP w/ a hand like {55} that almost always x/f flop (and is in pretty bad shape against a reasonable 3bet range) or {QJ} that's kinda also in not-so-great shape against a 3bet range (in this case he'd be pretty well smoked pre). That's an honest question from me, btw. I guess it's good, sure. You give him such a sick price to peel. And there's your 1st mistake: if you're squeezing here, you absolutely have to go bigger, especially w/ a hand that generates much of its EV from FE

I guess {JJ} makes some sense but figure those get 3bet at a decent clip so by all rights we have to discount that hand.

If my math is right were getting like 3.4:1 to call it off? I don't see how we fold against a guy who apparently is prone to some indiscriminate aggression w/ several unblocked combo draws and NFDs in his range. Not exactly thrilled though (and I'm a payoff wizard), and when we flop TPTK in a 3bet pot w/ SPR ~2 we should be fairly thrilled--clearly something went awry prior to this point.

Cbet smaller IMO, 250-300k does the trick. Especially if your not happy getting piled like this.

Oops, didn't realize you have Ah.

Yeah that makes this an even ****tier spot, and your flop sizing even worse (you could go even smaller than I suggested, like 200k). IDK, w/ that Ah blocking so many of his NFDs that would play this way and make up the bulk of his natural bluffs, this is much closer a decision. In reality, you'll probably just be mixing calls and folds, so flip a coin, it's that close IMO.

And I don't care how "established" this dude is, if he's blasting off here with a total airball like 87o or w/e then either one of two things is true: he's a huge whale, or he's a sicko who's somehow got some ultra sick soul read on you, and if it's the latter then no one here can help you w/ any good advice because V would've known something we're not privy to. If this is total complete air, I'd be happy to be at his table and I'd hope either I or if not I then he wins this event because I'm pretty sure that cash is coming back into the poker ecosystem eventually.

One more ? for you: is the board [QxJh5h][4c] or [QcJh5h][4c]? IF the latter it makes a big difference bc at least he'd have some club draws that would make for natural barrel bluffs

Live read spot
Idk why were going nuts against a 2CL pro at this stage of the mtt tho. Pre could be flat or 3! (fine), flop could be smaller or check. Holding Ah I’m sigh folding to the c/r if V is never slowing down ott.
The only time I’m continuing here is when V is OOL, I’m trapping and the turn is a triumphant snap. Based on OP that’s not the case.
V could have T9 or hh or KT for sure btw, but also KK+ sets QJ. Seems an ideal spot to pot control on an awkward flop where V range could apply a ton of pressure.

Call pre.

340k is such a bad sizing

I agree. There isn't a lot that they are going to be folding to that 3 bet. your 3 bet (especially with a caller in between) should be 420K minimum to 500K.

There is no getting away from it now with TPTK on this flop. He raises you on the flop, just stuff it in. If he has 55 GL to him. But he can easily have a hand like Jhth or KhQh or even some other draw hand. To call the flop and fold to his turn shove is super exploitable. He should be playing all his draws this way if you are going to fold AQ. What hand do you need to call his turn shove? Are you folding AA as well here? Please don't tell me you need to have a set to call this shove.
