That's a fairly common SNG situation. Personally, in that spot, i stay away from the big stacks as much as possible unless i'm playing a group 1 hand(pardon the sklansky-ese), and pick on the short stack myself if the others are leaving him alone. Of course, the ease of that depends on your relative position to the short stack, but in situations like that, sometimes you have to take things into your own hands. Play smart, but if you're folding every hand and hoping he gets knocked out before he has a chance to double up, you're going to be in rough shape with not much hope of more than third place money... when it even works. By gambling a little with the shorter stack, you might lose out on a couple of cashes, but you will inevitably be in better chip position once you get into the money.

My two cents.
