It would be a shame to waste such a hand and it think it's a risk that you have to take. At this point, your opponents might even try to steal the blinds with speculative cards, so they might not even have an A in their hands.
BB big stack
SB me - shortest stack
UTG - goes all in
Button - goes all in
My turn
If I'm going all in, it's a third allin and its a 20% of stack to call for BB.
Fold: You have about 2800 chips, and there are two big stacks with about 5500 each. You have about 20% equity - so in very rough figures about 20% chance of winning the main prize, about 28% of winning 2nd and the balance for third. Doing the sums on that (assume there is $100 in prize money for simplicity), you get (20%)($50)+(28%)($30)+(52%)($20)=$10+$7.40+$10.40= $27.80
Call. Your equity now depends on what sort of hand your opponents have. Lets say we assume that they have 66+ or AT+ which isn't totally unreasonable. Against one of these hands you have about 72% equity, but against two that drops to about 57%.
If you call and lose you have 0 prize money - 43% of the time
If you call and win (57% of the time) you'll have roughly 60% of the chips, so 60% of the 1st prize equity, and 40% of the second. Your equity is therefore (57%) {(60%)($50)+(40%)($30)}=57% of $42 = $23.94
So folding is actually better in that situation.
