Thank you guys for the inputs!
I ended up folding this hand which was not the right or wrong decision, since it was obvious we're gonna flipping once I'm calling this down. Opp had A8o this time, and ended up hit the 8. SB called this shove as well, which was kind of obvious considering the dying stack of his.
My main thinking line was to remain close to the bigger stacks on this table, and picking up a spot with even better cards or being the original agressor. The small stacks also had 1-4bbs when it came to FT situation at this point, so I felt myself more secured not flipping my 1/3 stack away - even it was small either way. 77 is very good, but at this point maybe fold is acceptable as well, especially if you trust your small stack game and the rotation of the game, even tho my aim is always to reach the highest, not determine myself only the next payjumps.
So these aspects made it tough. It's a super small stack game here I guess.
You said
@300HPGOD that BB shoud overfold here the 88-99 which is totally right I believe. He had the biggest VPIP at the table (30%) which is not that small, not that far from optimal too, might scare me away too this time.
Well, I was happy to see that 8 here cause I was not feeling myself a clown totally by folding.
With this stack and these conditions this time I survived until 7th place if I remember right. I shoved 55 from UTG+1 which was another tricky one since I was last there and pretty card-dead, but stacks were still low and BB with a similar stack called with that same combination: 77.
So once again, thanks for your detailed answers on this one
