i dont agree with you limp. People who limp with strong hands like QQ, KK, AA as SB take a higher risk of getting beat with crap. I would of raised preflop, and if he has 9x, he will most likly fold, butat this level the donkey will probably thinks your bluffing and will call. If he raises pre or post flop, i would call and put him all in post flop.
