If there's any chance that the other player is going to keep bb on life support by folding his sb to him, you need to call/min raise, and fold. This will kill the bb, as he'll have 130 in chips, 100 of which will go into the sb, and he'll fold no matter what. Once he's down to 30 chips, he'll be racing the rest of his money in 2/3 of his hands, and he'll be gone. It feels like a sin, but the best move is to limp in, and fold to the sb's raise. If he doesn't raise preflop, you can min bet on the flop. At that point, there's no way for bb to possibly win if he's sitting out. Of course if you flop a Q, you're playing for all your chips. The only way you could fold if you flop top set is if there's a draw, and you honestly believe sb might be drawing to a flush or something. That's an even tougher situation.
