When I get ITM in a SnG I usually get assaulted with all ins which force me to make decisions fast. Also, usually by the time it gets down to three people the blinds become a big enough agressor to take that role away from the other players.

That being said, it seems like when someone is in your position they certainly go after the short stacks. Of course, as you can tell, im usually the short stack in these scenarios...so I can't tell you how to play it, only how it was played against me!
