Against the Danish Gambit, it can be best refuted in the variations:
1.e4 e5 2.d4 exd4 3.c3 dxc3 4.Bc4 cxb2 5.Bxb2 Bb4+
1.e4 e5 2.d4 exd4 3.c3 dxc3 4.Bc4 cxb2 5.Bxb2 Nc6 6.Nf3 Bb4+ 7.Nc3 Nf6
If you can ride out the storm for a while, then the two advantage will prove itself in the end. This is the way to win against the Danish. Theoretically, it is very good for black and borderline winning if played correctly.
