=Ruy Lopez Open Defence=

Black is temporarily two pawns up, but there is a loose knight sitting on an open file leading straight to her king. Why not attack it with 7. Re1 ?

7. c3 is just getting silly. Black will be two clear pawns up and as in the Danish Gambit, she can give one pawn back and run off with the other.
