Hypothetical $EV vs. table dynamic situation

Standard Party SnG payout structure, 3-handed. Blinds are 50/100, stacks are:

button, 2500

SB, 1500

Hero (BB), 6000.

Button folds. SB pushes all-in, accidentally revealing AKs. You look down at 44. How common would you say it is for folding to be correct in this spot?

Honestly, I'd base it on whether I play better 3 handed or HU with smallish blinds. There are some other factors involved such as caliber of the players, how aggressive the table has been, etc etc.
