Any better alternatives?

It's the "in for a penny, in for a pound" principle.  If you've already lost your b2-pawn (the stereotypical "poison pawn"), you should play energetically by being willing to shed another pawn to open up the position while black is way behind in development.  Just look at the position in the computer's line after 10.0-0.  Black is three moves from castling, and white's totally ready to blow the game open, sacrificing more material if necessary to get to black's king.

You won't understand it in the way the computer does, but I think the "in for a penny, in for a pound" principle is useful here.  When you're ahead in development (and down material), time is everything.

I suspect there is a tactical refutation for White here, a refutation for Black misplaying with ...Nc6 (usually Black must play ...c6) and ...Qb6, but I don't have time to look for it right now.

In this opening White usually plays Bc4 (which prepares for d5) and Bf4 (which takes away flight squares from Black's queen), and the winning attack usually comes in the form of the pawn advance d5 and/or some piece maneuver on the queenside that traps Black's queen while it's under attack. Since in this game d5 would drive away Black's knight at c6 since Black neglected to prevent that pawn thrust with the usual ...c6, I would look at lines based on that move, maybe also with moves like Nh4. The Scandinavian Defense is precarious and is full of opening traps where White wins quickly. You just have to find the tactical refutation.

P.S.--

OK, I found the tactical refutation. Sure enough, Black's queen gets trapped and lost if it steals the poisoned b-pawn...
