Danish Gambit Tactical Defense

The Danish Gambit, known as the Nordisches Gambit (Nordic Gambit) in German, and the Noors Gambiet (Norwegian Gambit) in Dutch, is a chess opening that begins with the moves:
1. e4 e5
2. d4 exd4
3. c3

White will sacrifice one or two pawns for the sake of rapid development and the attack. However, with care, Black can accept one or both pawns safely, or simply decline the gambit altogether with good chances.

If Black enters the Danish Gambit Accepted with
3...dxc3, the main possibilities are 4.Nxc3 and 4.Bc4.
