2nd pair in 4bet pot

I'd just get it in.

You have basically a click back left behind. (~107 - 35 = ~72). I don't see how you can fold and a call seems a little off OOP at this SPR with possible draws (AJ/AT/JTs) etc.

Even splashy, does anyone VPIPing 27 snap call a 4-bet and a c-bet with JJ, QJ, or AJ (or worse)? Maybe JJ. I can see it happening to a bunch of things he loses to, however (AA-QQ, KQ, AK). I would tend towards folding, personally, but I'm also a n00b. 😉

I'd feel better if he jammed. AP would rather have a proper showdown tier read but open to ideas

He looks like a fish with that gap between VPIP/PFR so always call turn and call river.

Also his 3bet sizing is a bit big which also trends toward fishy.

Doesn't that gap indicate a more linear 3b tho?

Fish 3bet much wider and don’t fold to 4bets. They also don’t fold to cbets in 4BPs and C-B much more than theory.

The turn B50 ( I’m assuming the rake isn’t taken out in this 71.5BB pot) is a classic fish sizing so you just call turn to bluff catch all rivers.

You can also use small sizes like 10-20% on flop and turn on a lot of boards.

4bet is too small. Probably best to block turn again, this sizing leaving 35bb behind looks super nutted.

Ya, turn is close really. I'd fold against most opponents there. With your read it looks more like a call/call situation. You're a bluff killer now.

Thanks for the answers!

Really, what 4bet size would you use?

True, I see solvers like to bet very small in a lot of 4bet pot spots but I'm not too familiar with it, and I fear against my pool it might induce raises I don't want to face.

Seems unlikely considering people don't even raise tiny flop cbets enough.

To me it kinda depends how much value you think is in their preflop range, do they call KQo here to 4bet? If so they can have a ton of value here. Vs a reg it is easier since they shouldnt have KQo and so for value they will have 2 combos KQs, maybe some AKo (most like to shove in these formations) and maybe 0.5 combo of QQs and 1 combo of AA(I assume they shove sometimes). In terms of high equity bluffs, which I assume is all the 10nl pool will use for bluffs, you block a ton with Ah. (AJhh AThh A5hh A4hh).Sure there is still JTs T9s, and 45s, and the suited connectors, but checking turn shouldnt really cap you and I would guess connectors fold flop. So unless this guy has low equity/ no equity bluffs by floating wide on the flop, I think it is a easy fold. I would note the timings though - maybe you can pick up a trend over some showdowns.
The sample is still small so I cannot say this guy is a fish, fishy at best but if there is a weaker player at your table they may just be flatting btn more - not so straight forward.
It also depends how thin the guy can go for value on the turn, if this guy is fishy, they can now have KQo KJo ect and can stack off any top pair.
Vs somewhat competent preflop regs their value range is much narrower so a call is much more reasonable if they can be aggressive. I think in general most regs will check back KJs or KTs rather than bet this size meaning they end up with a very narrow value range. And it is important note you have a pure bluffcatcher.
