How low are the low stacks? What is the 'M' here...?

and if you fold, you'll have to push all-in fairly soon anyway and AJ is a pretty good holding to be honest......at $0.5 it's debatable whether big stack is leveraging against you but they may be...

All questions you should be thinking about..

If its the bubble and you have two lower stacks, you should not be shoving even JJ in early position or AQ or AK. ICM dictates that you have too much prize pool equity so you can not shove AJ in this situation. You have to fold all hands until you are either a short stack and must push, or wait until a shorter stack is busted.
The worst thing that can happen is you go all in and big stack calls you when two stacks are lower and the two short stacks make the money

What are the stacks? If the "short stacks" are like 1 bb shorter than you that's different than if they have like 3bb and you have 10-11 bb.

As what the guys have said................main thing to look at is stack size and ur hud or read on the big stack stats.

depends on the stack sizes of the short stacks at the table
