Danish Gambit

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.  (Source: Wikipedia)

The text is part of the Danish Gambit Accepted.

3. .... dxc3
4. Bc4, cxb2
5. Bxb2 ...

Analyzing the position, White has more active and developed pieces (e.g. Bishops), which, if Black is not careful, may be instrumental in assuring White's victory.

5. .... Nf6
6. Nc3, Bb4
7. Ne2, Nxe4
8. 0-0 ...

If 8. Qd5 Black replies Nd6.

8. ... Nxc3
9. Nxc3, 0-0
10. Nd5, Bc5
11. Nf6+!! ....

Taking advantage of his two Bishops,  White decides to open up avenues of attack.

11. .... gxf6
12. Qg4+, Kh8
13. Qh4, Be7
14. Bd3 ....

Usually, Black resigns immediately.  He has no solution to an impending mate.
