I dont see how BB calling with AA, or even KK in this spot is a small mistake.

I mean if he loses he is down to 13.5K in chips and is still CL and can still most likely fold to a seat. If he wins the tournament if over and he can go eat dinner or go to sleep or what have you rather than grind it out for another hour or so.

I do agree the call with KJ o/s is pretty bad, as is the open push with 88. With such a stack and on the bubble I would be inclined to complete or make a small raise, depending on how BB has been playing throughout. THen I would hope to check it down with BB, or value bet if I hit a set. If BB shows aggression with overcards on the board I am gone.
I think there's a decent chance that with the stack you have you can sit back and wait and see what happens. Usually I find someone else makes a stupid move and the tournament ends. Either that or the shorty pushes and someone else makes a bad call...or a good call...and busts him.
