HI Jeff_ Have you checked your WR with these hands? I did earlier for calling 3 bets, which was under -250bb/100 but even that was a small sample for me. I know Krystov said SCs do terrible vs 4bets but they do ok in BvB situation.

I didnt check because I dont call them and I dont have big enough sample on winning regs to check out how they are doing.
However ranges I got (from HS reg) dont suggest calling it :D

Particularly at small stakes population quite heavily under 4Bs, as well as probably choosing a larger 4B sizing than you have here (as you note). I think I would probably choose to overfold some of the A8/A9s/A4/A3/K6 type combos and reduce the AQo call frequency to reflect this. I dont think it would be horrible to continue them all however if you are studied in 4BPs since I think population at lowstakes also plays very badly postflop

I think it'll play the same. Pio's raising range wont differ that much from lowstakes population in this spot I think on the T. Its basically comprised of TX,sets,combo draws and some 87. Its just a classic low SPR trait where Pio would rather polarise and bet hands that dont lose ev when they face raise.

Also in what direction do you think population will make calling mistakes? If they raise the same range and overfold, we still rather bet the polarised hands and ramp up the frequency of bluffs. If they overcall and raise the same range, we do the same but in reverse - it is only if they underraise that we barrel the linear equity combos at a higher freuqency

Mostly referring to the 2nd part. I think the calling mistakes come from hands they should be raising with and the occasional call with under pairs or bottom pair that should be folded to a double barrel. It's like you 3 bet preflop and they just put you on AK and call all the way down no matter what the board is.

I am usually pushing my higher equity draws against the pool because I do not think they raise often enough on turns or rivers. I just filtered for this turn opportunity to 3bet and it's a very small number of hands despite my sample to illustrate the point, this is for all SRP and 3BP. My barrel turn success is only 39%, not sure what the number is supposed to be, but that seems way too low and points towards a lot of calling stations.
