Max Lange Attack (C55 – C56)

The Max Lange Attack is a chess opening that can arise from many different opening lines, including the Two Knights Defence, Petroff's Defence, Scotch Gambit, Bishop's Opening, Center Game, and Giuoco Piano. Two of the most commonly seen move orders are:

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 (the Two Knights Defence) 4.d4 exd4 5.0-0 Bc5 6.e5
1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 (the Scotch Gambit) Bc5 5.0-0 Nf6 6.e5.

It is named for the German master Max Lange, who suggested it in 1854.

After 6.e5, Black has two main replies. Black's 6...Ng4 is playable, but rarely seen. More common is 6...d5, when the main line continues 7.exf6 dxc4 8.Re1+ Be6 9.Ng5 Qd5 (9...Qxf6?? 10.Nxe6 fxe6 11.Qh5+ followed by 12.Qxc5 is a notorious trap) 10.Nc3 Qf5 (10...dxc3?? 11.Qxd5 wins, since 11...Bxd5 is illegal) 11.Nce4 0-0-0 with complex play.

An alternative for White is 8.fxg7 Rg8 9.Bg5, analysed by Lev Gutman and Stefan Bücker in Kaissiber, which they consider to be good for White. Black's usual response is 9...Be7 10.Bxe7 Kxe7.
