Thats technically not a bb special since you are in the sb. I don't know the buyin either, if its a low buy in, I wouldn't be suprised to see seat 1 just trying to steal a pot with air occasionally, but the higher the buyin, the more likely you are beat. Low 2 pair is a hand that can very easily be counterfieted, and I think I could get away from this raise.

You should have never called in the sb with that hand though, so fold preflop.
