I tried to explain a friend of mine, that there happened several mistakes or bad play in this preflop situation:
6 Players left
UTG (355) with 9♥9⋄ moves allin
UTG +1 folds
UTG +2 (1,300) calls with A♣8♠
BTN (2.800) folds
BB (3,220) folds
First I think it is a common move as an absolute short stack to go allin with 9♥9⋄.
Second I think UTG+2's call is not a good option. Especially because he has no chance to do anything but fold when BB moves allin. He showed weakness with just a call instead of an allin. But on the other hand, what should he win with an allin? Show strength that everyone behind him folds. But he would get calls only by strong hands and would probably loose with A♣8♠.
Worst that could happen is, that UTG wins and BB's hand still stronger than UTG+2. So he would leave this table on 6ths place and win nothing. Not so good, but still possible would be that BB wins all and he has place 5th with 0 chips -> +-0$ for this table.
Third I do not know why BB didn't shove allin to push UTG+2 out of game. See above why I think that would have worked. And even a call would be cost only 155 chips. Well, he might think that this UTG+2 call is just a trap? Or that he just want see if UTG+2 beats UTG, so this table is over.
Am I right with my thoughts about this situation or was everything all right and I just misunderstand this situation?
