Danish Gambit, Collijen Defense[edit]

The Danish Gambit, Collijen Defense is popular among club players, but not so popular at the highest level. That is because, it is easy for black to fall into one of the many traps on this line, but if black knows what to do, white can get no more than equality out of the opening.

White has two main options from this position:

4. Bc4
4. Nxc3

Although it may have been known earlier, Danish player Severin From essayed the gambit in an 1867 Paris tournament and he is usually given credit for the opening. The Danish gambit was popular with masters of the attack including Alexander Alekhine, Frank Marshall, Joseph Henry Blackburne, and Jacques Mieses, but as Black's defenses improved it lost favor in the 1920s. Today it is rarely played in top-level chess.

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