Description

The Lipnitsky Attack, also called the Fischer–Sozin Attack, is 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bc4, White's bishop sortie against the Najdorf, with the idea of playing against f7.

History

Veniamin Sozin introduced the move in the 1930s, but it received little attention until Bobby Fischer adopted it regularly. It was a frequent guest at the top level through the 1970s.

Main lines

Because the bishop aims at f7, Black usually counters with 6...e6 7.Bb3 b5. The Sozin has become less popular because of 7...Nbd7, after which Black intends ...Nc5 later. White can avoid 7...Nbd7 with 7.O-O, but that gives up the aggressive option of castling long. The same bishop move against the Classical Variation is the Sozin Attack.

The numbers

On Lichess White wins 48.0% of the 2.5 million games and Black 47.5%. Black does a little better below 1800, while from 2200 up White is ahead, 50.5% against 43.8%. In 7,689 master games over the board White won 31.1%, Black 34.1%, and 34.9% were drawn.
