Blinds are 75/150, eff stacks are about 25k

Woman in low jack raises to 350
Loose passive fish in HJ flats
I have AsAd in the CO - 3bet to 1250
Massive fish in SB coldcalls, PFR and HJ calls

4 way to the flop - 79Jss

Checks to me I bet 2600
SB flats, PFR woman raises to 6k

What do I do?

The fish in the SB instacalled (has done this multiple times showing a draw) and he will likely be shoving any turn that completes a draw especially the spade (and so far he's always had it)

Woman has slow played sets and strong hands before on dry board, will be willing to give up TPWK and calls down with TPGK (like QJ/KJ isn't a x/r for her, she calls down instead)

price seems good for me to call here but if the turn bricks off i think the woman is shoving, if the turn is a spade the SB is shoving

I don't really have that good of a turn card except an A maybe

I would prob sized bigger pre, since is a loose/weak table, but w/e.
I´ll most likely snap fold flop, cus this isn´t a dry board and we hold the A
Not to be results oriented here but vs 4 players i would try to avoid this spots and x/back flop (again, holding the A of spade is important and we´re not getting 3 streets of value anyway)

Yeah after the spot I really thought of checking back flop

I think bet/folding the top of my value range here is so exploitable

That being said checking back flop 4ways feels like im basically giving up on the pot really I'm literally at the top of my range and I can't bet for value against THIS table???

Idm taking an exploitable line here - I don't think anyone at the table is capable of exploiting it even, and especially given that it's a 4way 3bet flop I don't think people are squeezing that liberally either

But yeah huge reason in posting this hand was to see if people thought flop was defo a check back and why


Edit: also avoided sizing bigger pre to reduce variance and I was playing IP against a very rec table and wasn't worried about postflop play (lol). My image is good and this is the second hand I've 3betted (first I showed down aces) and am almost closing the action. If i was in the MP the raise is probably going to be bigger defo but that was my reasoning for a marginally smaller 3bet size

Don´t think some randoms are gonna try to exploit you here, in a 3bp, multiway, givin action etc.
So i say let´s exploit them by folding top of our range

Yeah, definitely agree with folding to the x/r flop for the above reasons

Am more curious about whether x back flop is a significantly/marginally better line and why

I didn´t run the math or made a simulation, so don´t really have a straight answer right now (not to mention i hate math and think is idiotic ), but basically, i would hate bet/f here, also they have all sets,two pair combinations and straights, pairs +FD etc. so we pot controling (for reasons mentioned above), cus i will hate to gii here and have like 20% when called (esp vs weak players), and calling flop to see a turn is just meh.
