PLO100 T876ds 3bet standard but what if...?
...we fold? Yes, at a loose table not being last to act having a hand with questionable nut-potential that can't push equity either, I think that's fine too. Calling is also an option imo if regulars behind us have significant mway leaks like a weak betting strategy or being overly passive. AND ofc overfold pre.^^
Now I dont think EV difference is quite that big in reality almost ever as our fold equity tends to be quite a bit lower than in theory.
The GTO EV difference is not that big? It's just ~0.15bb, BE basically (you lose something with rake but whatever). If there's a guy who cold-calls a 3bet and then everybody ends up in an all-in, solver probably is not very helpful for the specific situation. I think your thought process here could be flawed. Theoretically, if people are spewy, you'd rather take the passive line preflop (your mid-high rundown lacks preflop-allin domination potential but also performs pretty well on average being dominated itself less often which explains the equities - problem is as you already correctly pointed out, people just flat way too much oop). Hands that have BE or positive EV preflop in solver world benefit a lot from villain being able to fold against the 3bet. This heavily affects the way you want to construct your 3bet ranges (more than 0,15 bb). We need to add more higher ranks and premium pairs and fold more of the speculative combos like A+midpair or more badly connected mid-high rundowns. The T♠:8♥:7♥:6♠: despite being close in both terms of nut-potential and equity distribution (and for this could be folded against perceived tendencies) it would be still in the top-tier of my "rundown double-suited" category that's as a default tight 3-bet/squeeze against unknown.
Individual EV's should not be overvalued, they just represent a very tiny part of the stratagys' total EV, in this case the 3bet range where you still want to keep some hands of that category even so when the EV drops. So you could imagine it as "a hand with poor EV makes sure the EV of other combos from that line stay high". The 1-gapped rundown double-suited just compose a veeery smallish part of your overall 3bet range so it somewhat has a lot of "core-"character of ensuring a minimum of board coverage.Again when there is no EV gained by 3betting the combo itself and villain don't adapt when we put some of those hands into a different line, it depends on how villains ranges and perceptions and postflop play alters. Unless villain is an observing regular, those adjustments usually don't occur in a way, that can't be exploited aswell, but there's a higher risk of facing more difficult decisions later on when deviating early. So what I mean is, when you loosen up, villain will loosen up aswell to some degree but will find himself in spots he is unfamiliar defending and return to a point of his original (when reggish usually more tight) playstyle.
For the cold-call pre the top-gapper its polarized/deep-spr equity distribution is somewhat a sucker. The :6x::5x::4x: flop yields a nutstraight (without straightredraws possible, we'd need a :5x::4x:-x or :9x::5x::4x: to draw to a straight+redraw or have a :6x::5x::4x: or :9x::6x::5x: nutstraight+redraw. It's helpful to think about beforehand what we can hit especially being deep or in 5card. The hand is not trash like top-2gappers or top-bottom-gappers but significantly weaker than the :Tx::9x::7x::6x: and :Tx::9x::8x::6x: counterparts without top-gap. These are considerations to be made when entering SRP's. When villains are bad they don't have any perception of heros' 3-bet range so we don't need to balance our 3-bets and could call going for exploitative postflop play in position. Pre-EV solver-wise calling should be fine when implemented well but since CC-EV's in general suffer a lot from active players behind us I would argue openfold might be the better option (ie. with semi-connected :Tx::8x::7x::5x: or :Tx::7x::6x::5x: double-suited ie. would always recommend the fold in loose environements, all those good looking hands are actually suckers cause you can't hit those straight/-draws you want to continue at high spr well enough so with a substantial risk of being mway/oop there's actually no point playing em at all...
As played with dead money stacking off is no big deal imo, it's probably still somewhere around 0 unless their PF-ranges are well balanced or semi-tight and merged. An alternative more frequent scenario is that everybody calls which is probably pretty good if we play well postflop. So stacking off more loose here and there at marginal spots I often found helpful to have an image that gets paid, unless your pool is too big/anonymous you can also fold to avoid variance.
Call, Reraise, Fold?
