If 2 people go all in before you and thier are 4 people left in a sit and go tournament
Any hand can hit, one of the allins could have flopped a set -and it's not worth the chips, if you can go ahead to place. I'd rather place short stacked, then to miss with AA...and feel on tilt for an hour...lol.
Logically though, you should go allin pre-flop with AA (or AK) -if you are in 3rd...before anybody even sees the flop.
Nobody wants to be 4th...so it's easy to make people lay stuff down in that stage, so use that chip equity...while you have it.
