.05/10 6max PLO8 on Ignition. BB is short, only about 30BB. We're about 90-100BB effective with the rest of the table.

BB has been playing somewhat questionably, although not unusual for these games. Playing lots of mediocre hands and calling/getting quartered a lot. Seems like a typical fishreg.

Hero wakes up UTG with AKQ2 and opens to 3x. MP flats, CO flats, BU flats, SB folds. BB raises it up to ~5x, about half his stack.

Is this an okay spot to re-pot trying to iso the BB? Seems like the rest of the table is pretty capped after just calling my open, so not expecting them to ever really have monsters to be afraid of. Also seems like I should be pretty happy to get this in pre for 30BB with all that dead money on the table.

Anyways Hero re-pots and it folds to the BB who calls it off. He turned out to have A289ss.

Just wondering if this is an okay play to be making in general. What % of hands are we iso-ing in this spot?

I would probably just call my prime hands non AA hands, like A24k, a235,..... Could be a nice way to dominate the table in a big pot or throw it away if it misses. BB would likely lead out for the rest of his stack, if you call the pot would be 60ish blinds where you have a bit over a pot sized bet behind.

id shove my AA5x, aa4x,.... and shove the weaker a2xx, maybe even shove some a4qq hands too maybe even shove some good A3xx if BB is lose enogh

you should want to take the line that will maximize your profit.

you suggest that 3-betting pot with the objective of isolating the bb (anticipating that the 3 callers will fold) is that line.

when u anticipate correctly, your profit with that line is either 24.5bb*(minus rake) when bb folds to your raise, or your fraction of a 69.5bb pot(minus rake) minus your 30bb contribution, depending on your pot equity when you and bb showdown. showdown will most often be worse than when bb folds and its my guess it will happen more frequently.
*figuring bb's raise as to 15bb.
as an estimate: +23.5 when he folds, +8 when showdown, if showdown ~75% then 'iso line' = +11.8bb

why don't you try to figure out the likely profit of the lines that begin with 'calling the raise', and see if they exceed +11.8bb.

i suspect it will.

Either is fine, but regarding the math of it, it's impossible to calculate. It's easy to speculate about preflop equities based on holdings for the all in player, but when you have to play poker postflop, you can no longer calculate it, so doing the easy one and asking him to do the hard [impossible] one isn't very nice.

I suspect it's a pretty close call either way.

Super easy 4-bet with a hand this strong. Push equity.

impossible is ridiculous unless you are hung up on the word 'calculate'. i didn't i use it, i used 'figure out', might have been better had i used 'investigate'. regardless, i'm not interested in participating in a semantic discussion.

the decision tree involved with calling is certainly more cumbersome than "the easy one I did", involved with raising. But utilizing assumptions and that some factors involved with this hand will simplify it, an analysis of calling, the purpose of which is to recognize some limits of calling and provide some ev estimates of calling, in order to provide for a comparison to raising is doable.
i'm also not interested in getting into a more involved discussion about it than that.

i'm compelled to leave this thread with the comment that i find it weird your response to the OP follows the form of a comparison "Either is fine", and "I suspect it's a pretty close call either way" and yet you don't find my suggestion of a comparison helpful.
