Chessbook - Charlie Storey - The Sniper (2011)

The Sniper – based on a system of development with 1...g6, ...Bg7 and ...c5! – is a dynamic weapon for Black against both 1 e4 and 1 d4. Black allows White to occupy the centre but, in true hypermodern style, strikes back at once. The Sniper is a fascinating opening that can lead to original or barely-known positions in which White is thrown onto his own resources and Black can strive for the initiative. White also has to negotiate a minefield of transpositions, typically into Sicilian, King’s Indian or Benko-type positions.
Charlie Storey has spent years refining his favourite opening, testing it out successfully against players of all levels. In this book he reveals all his secrets and provides you with everything you need to know about this fascinating opening.
