Think the deciding factor here should be the likelihood of getting called twice. If we shove, do we think V1 is likely to be aware enough to reshove over V2, making V2’s call dead money? Or is there a possibility that V1 just flats, and V2 flats behind? Judging by your player descriptions, I think it’s the latter, in which case I think folding ATo is acceptable here since our 3-way all-in equity will be quite poor. I would prefer going with a hand like KJs or something else suited and conneced if we think there’s a reasonable chance of getting all-in 3-ways.

We don’t really need fold equity to get it in here though, obviously, since a) we don’t have any, and b) we’re risking our 6bb to win around 6.5bb that’s already in the pot, which will go up to 14.5bb if both players call our shove. It’s early in the morning here but by my estimation, adding our 6bb to the pot and dividing it by what we’re risking should give us an equity threshold of around 29%, if I’m correct. Against two somewhat loose ranges, ATo has around 29.6% compared to KJs having around 31%, but when the ranges get a little tighter, KJs stays at around 29% while ATo drops to 25%.

It’s pretty borderline either way. If we expect V1 to isolate us and make V2 fold 100% of his range, I think it’s a clear shove. But if we expect to get all-in 3 ways, it might be slightly south of profitable.
