The 'Anti-Sicilians' have invariably been a popular choice at all levels of the game. Analysis of this opening in previous literature has rarely been extensive due to the misconception that Anti-Sicilians are simplistic and thus, easy to play 'by hand'. While maintaining the ideals of straightforward plans and digestible variations, this series of volumes will attempt to integrate 'Anti-Sicilians' into mainstream theory - with a particular focus on negating Black's attempts to achieve any significant activity. This first volume provides significant coverage of the Rossolimo variation - perhaps the most pertinent example of how an 'Anti-Sicilian' has emerged to become arguably even more popular than its counterpart, 3.d4 after 2...Nc6. With a particular emphasis on analysing multiple alternatives within each critical variation, this book should appeal to anyone wishing to update and expand their knowledge and understanding of the fashionable Rossolimo.
