There is a new, lengthy post/thread on p5s about sng bubble play. The dynamics have to be right, but it is interesting. To save you the read, basically you want to become ultra-aggressive if there's a short stack (and, preferably, you're not risking your tournament). That means folding AA if it keeps them around, and pushing the rest of the time, since the first-in vig is huge while they wait to bust shorty.
