MP2 is the table mark, running at 56/18/3 over 300 hands.

BTN is 23/21/1.6 over 114 hands. 9% 3bet (2/4 from the BTN when the hand was played, I remember checking). 78% steal. Not seen him before but he's topping up and positionally aware, so probable reg.

I don't have what I was playing at the table at the time, but hero's image is usually nitty.

I'll save my thoughts until we get a few responses, but it's fair to say I considered everything here: call, 4bet/call, 4bet/fold and just open fold.

Call. Or 4bet/call are the only options i like.

Folding is way too nitty and 4bet/folding is probably going to be dumb against either of the two players ranges in this spot.

4bet/call I like... We get fold equity from 1010/JJ and since other villain opened from CO his range is naturally wider

Folding may sound nitty but if you hate AK OOP I don't think its that bad. Calling turns hand up

I like 4bet/call better than folding. Folding isn't terrible though.

I 4b/c here and would prob just call if I were ip...The btns 3bet is always for value but he can be very wide for value given how bad the pfr is

I like call the best.

BTN is less likely to be bluffing a bad fish here, and is more likely to be heavily depolarising his value range to hands like 88+/KQ+ which means we dominate big chunks of his range. His 5b range is likely to be dropping the hands we dominate in favour of the hands we flip against. By flatting, we let the fish in with lots of Ax, Kx and get to stack the fish postflop and even sometimes stack the LAG sometimes when we hit dominating flops. This has to be preferable to 4b/calling where we are basically going to be chasing the fish out of the hand and inducing a flip with only a small amount of dead money in the pot.

The downside is that we are going to have to play fit or fold postflop, but that's fine, because when we do hit, we're going to get a lot of fat value a lot of the time.

agree with njd77 about preflop... postflop i woudn't necessarily play fit or fold.

I agree mostly with this, but it doesn't matter when the fish doesn't know how to hand read. If the original raiser was a regular and we suspected that the button was 3-betting light and also depolarizing his value range, I'd then prefer to 4-bet, since it's hard to play when both villain's can play pretty optimally against us.

Fwiw, I see nothing wrong with bluff raising on the button (ideally with some cards with some high card strength) if I assume that the Villain is going to call with his entire opening range and fold to a ton of flop continuation bets.

well you're at least giving up an almost surely unexploitable +EV spot... which would at least be really bad.

I don't like 4betting. Even in this situation, a cold-4bet is going to look very strong and while we might make TT-JJ fold, we're also going to make him fold the rest of his wide value range like AT+/KJ+ while being in only marginal shape against his shipping range - and we're also usually going to force the whale out of the hand.

The value here is in calling and playing a hand that's a) ahead of the reg's 3betting range in a situation where he's going to play fairly honestly and b) crushing the whale who's probably going to call the 3bet after you call.

+1000 I don't mind 4betting here and it's definitly not a mistake but as stated in the 2 awesome posts above; there's just a lot more value when we do hit a decent board instead of picking up the dead money most of the time

edit: only downside is that our range is pretty face up.

Thanks for the replies everyone.

My first thought was to call (primarily to keep the fish in the pot), and I think if I could have the hand over again then that's what I'd do. I talked myself out of it because of being OOP and having a face-up range, but perhaps that doesn't matter so much in this spot. Keeping the fish in is key, he doesn't care about my range and will keep the reg a lot more honest.

Results were that I 4bet to $6, fish folded, BTN shoved, I called and sucked out on his KK.

Sure
