Raise the SB to t300 on the flop instead of just calling. Most people will realize that you have at least two pair and it will be tough for anybody else to reraise with less than two pair.

I'd be willing to call one person's push or to reraise all in if only one person reraises me. If somebody else pushes and then the SB or another player calls I fold (or a raise and push by two players). Only hands you are worried about are 55, 99, TT, and 9T all which could be out there but I'm willing to go broke against one player since I've seen some horrible play in these 180 man SnGs.
