Guy on button on my SB. has been opening a lot.
i have thus far 3bet him twice and CR him once successfully.
blinds are 300-600, folded around to him and he opens to 1500, i make it 4500 with AKo, he tanks for a while and makes it 10100. he is playing around 50k and i am playing around 85kish.
what do we do ? i dont have any specific reads on him.

Do you have any reads on the guy besides the hands you played against him? Does he limp a lot? Has he 3-bet or 4-bet at all?

- He is sort of an aggro leaning towards the fishy side - saw him once snapp off cuttoff vs button with jj against ak pretty early for like half his stack on the second blind level ..
my thoughts were as follows.

1- I didnt want to put it in that early when i have a decent post flop game as opposed to the field.
2- i didnt want to flip and have to go back to less than starting stack.
3- iv only put in 4.5k and i will have better spots.

does anyone actually suggest flipping at this point? i might have been drawing slim too ..

I'm worried we have no fold equity. I'd probably just fold.

I doubt he's doing this with anything you dominate. Flip or fold. Even with antes in play I probably wait but make a note of this. The good news, you have position on him everywhere but here.

Folding is out of the question.

I see only 3 options here

1. Call and see the flop and depending on bet size and board texture you can decide what to do.
2. 5 bet with the intention of calling all-in (eg. raise to 25K and call his shove).
3. Raise all-in and put the pressure on him.

Folding to a mini-4 bet is out of the question unless you can specifically put this guy on AA. Can you?

What do you think his 4-bet range is here 83bbs deep?

BTN-Sb?

Obv this.
Prob not a lot of players 4bet/f here esp in a livedonkament, but SB/BU givin that you already 3bet him twice, i will take option 2. (folding is not an option)
UL if he had AA.

Depends on what hands you put him on. You said he opens a lot of pots, so he could have a wide range on the button. Facecards and pairs, J-10 suited, even 98, 87 suited. Re-raising with AKo helps you with his range. With him reraising to roughly 15-20% of his stack, he has narrowed his range considerably, as you have narrowed yours. Without more information about him, its hard to say how narrow we can go. Would he pop you with 10's because you have 3 bet him a couple of times? Not sure. I would likely give him credit for a good hand, and he is excited that he gets to hit back at you. AA, KK, QQ, JJ maybe, AK, AQ and that's probably it. AQ might be a stretch, but possible if he doesn't give you credit in the small blind. Against that range, your AKo has 50.1% equity. If I am in that spot, since I am a flip against that range, I am going to see a flop, watch his reaction to the board, and go from there. Given the blinds, it seems to early in the tournament to be folding AK.

How did he react the last two times you 3 bet his button raise? Did he fold, call, reraise? Have you seen any of his button raise hands?

Easy 5bet jam gii here bro

With the amount of counter-action you've already given him with two SB 3bs and a check-raise, it's very possible that he thinks you're wider here. I like the idea of a 5b/gii, too. 25k leverages his stack just perfectly.

Easiest areeeeee in ever.

Lol at anyone suggesting folding AKo SB/Btn to a 4bet. If you actually do that you're the most exploitable player ever if you want to have any sort of 3bet range.

Are we just assuming Btn never 4 bet bluffs? Its a $1500, anyone remotely competent should have bluffs.

+1 for gii. Yeah you're flipping a lot. But the nature of poker, especially mtts is to push small edges.
