Given the small SPR i would say that both options are fine.
I guess i prefer flatting as he might XR polar here and could have a range that folds turn but barrels off river if we flat. But i guess most of these hands will be gii OTT as well. Not sure if he is going to b/f like 89hh here

after breaking this range for villain down for what I think they'd have pre, what theyd have doing this action on flop, and what i think theyd have doing this action on turn, QQ has 80% against the range before you shove.

One thing I've learned from playing in a very fishy pool is that they follow through with bluffs on river so rarely that its almost negligible as a possibility (aka you wont get value from "slowplaying,") but they will pay to see draws going to the river, so I am on team fastplay in situations as such.

jam seems good in that it denies draws their equity and wins pot outright on the low SPR after his turn bet. with higher SPR, a call is probably good imo

NH.
I prefer to call hands like AA,KK,JJ,AJ.
QQ is just more important to get in and protect it's equity against hands like KTdd ATdd,QK and stacking AJ KJ before the board gets terrible.
You're sometimes loosing to sets here but thats supposed to happen, you just go broke with QQ here all the time BTN vs CO if he got you beat, np nh.

looks like you played this hand well, solver approves, mostly playing shove on turn w/overpairs that want to deny equity, you also unblock AJ/KJ that are higher freq x/r from villain that block turn and need to call shoves, unblock fds as well that have to fold to a shove, etc...for bluffs solver is mostly using mergy pair + sd type hands that block 2p and sets but have equity against calling range to improve

His flop raise size is so tiny, it just looks like it's only valuebets (in his mind) or clickbacks that don't believe you, which just give up on the turn.

The small raise size indicates to me that he's probably a fish. And fish don't normally bluff raise small.

This line looks a lot like JJ, 66, 44 & AJ. Against that range, we have 48% equity. Sometimes he flats with AJ. People aren't always stoked stacking off a pair of jacks in a 3bet pot. If we remove 50% of his AJ, we still have 38% equity. I think this range is probably a little bit to narrow. Occasionally, he'll show up with like KJ (let's give him 2 KJ combos, that brings the equity up to 41%). It really helps if we have any reads on villain. Even timing tells can be helpful. Snap / fast bets tend to be more for value heavy in my experience.

I honestly believe that we're slightly behind his range. I would call the turn and river (given normal sizing OTR), hoping he's spewing with something random some of the time. Against a tiny river bet, I think we can comfortably ship it and still get value from Jx.

Would love to hear more from other people and what he showed up with too. :) Perhaps I'm too conservative.

Dont think you need any shoves on turn. Any hand strong enough prefers to just call and the more vulnerable hands cant shove with this spr (still too large).
