It is named after the German chess player Adolf Anderssen, who was known for his brilliant and imaginative play. The opening is part of the larger family of Italian Game openings, which are characterized by the moves 1.e4 e5 2.Nf3 Nc6 3.Bc4.

In this variation, White sacrifices a pawn on d4 to open up the center and create attacking chances. Black accepts the gambit and tries to hold onto the extra pawn, while White aims to exploit the open lines and diagonals for their pieces. The key position arises after Black plays 7...d5, which is a counter-attacking move that aims to challenge White's central pawn on e5 and open up the position for their own pieces.

White's response, 8.Bb5, pins the Black knight on c6 and puts pressure on the d5 pawn. Black then plays 8...Ne4, attacking the White pawn on c3 and threatening to capture it with the bishop on b4. White captures the pawn on d4, and Black responds with 9...Bb4+, putting the White king in check.
