I see a couple of people saying to push, with no exceptions. I think pushing when the big stack is the BB is particularly bad if there is a significant (to the OP) difference in prize money between 2nd & 3rd place. If you're called, you're most likely behind. If you're not called, then you overbet your hand and a bet of about 90k would have accomplished the same goal.

Why does everyone like to push here in the case where the big stack is the BB?

Maybe this is the wrong audience for this question, not sure.
