Depends on villian's jam range!
1) If villian wants to balance his range, and jam everthing he would open here, it's an ez call.
2) However, players are morely likely to jam weaker Ace, or lower pair 22~66, because these type of hand are hardly to play postflop, and also do not want to induce a rejam. Under this condition, it's a fold.

At least, after this fold, we still have 15bb left. And we can try to find another better spot to ship it in with more fold equity.

If villian is a solid player, after betting around 64% in a multi-pot on this board, he would never fold to ur jam.
Under this condition, if u shove and villian calls, u need 41.9% equity to break even.
However, against villian's assumed range: ATs,As9s,As8s,As7s,As6s,As5s,As4s,As3s,As2s,KTs+,QTs+,JsTs,ATo,KTo+,QJo, 39s only takes 35.2%.
So i don't think it's a +EV spot, even not considering the bubble factor.

How about just call a bet and peel a turn, 'cause villian kind of commits there no matter what card landed on turn. I don't think it's a good idea either for 2 reason,
1) If T landed on turn, we are defenitely not sure this is our outs.
2) Condering our stack, we can't afford that loss.

So i sign fold!

Really curious why u decided to flat btn 4x with A8o @blinds.

Can't agree with u more! There is no reason to put urself in such a tough spot with A8o.
If no specified read for btn 4x raise, it's an easy and obvious preflop fold.
