In stealing situations, I open the SB very wide. Against steal attempts, I tend to defend just like the BB, as long as the guy to my left is tight, or passive, or both. In raised pots, I tend to play it like UTG+1. In multiway raised pots, I'm looking for the kind of hands that can flop big and hold up to multiway action: pp's, ATs+, etc. Like stacks said, it's situational.
