You want SB to push here. I min-raise because it looks to an aggro SB like I'm saying I can handle BB, but I don't want to risk busting. This is the perfect time for an aggro SB to resteal.

SB wants a situation where he pushes and BB folds, leaving you with a tough decision. If you limp BB won't necessarily think you're committed, so he may call SB's push given the pot odds and the greater probability you will fold if he folds. If SB knows this it makes it less likely for him to push. Actually, raising to 1000 is probably better because it gives SB a nice side pot even if BB calls, making SB more likely to push regardless of what he thinks BB will do.
