The book presents a Black repertoire with 1 e4 c5 2 Nf3 Nc6, based on the most aggressive Sveshnikov lines.
It also covers The Rossolimo (3 Bb5) and Alapin (3 c3). The material is up-to-date to April 10. The authors propose major novelties in practically all topical lines.
The repertoire avoids solid, but passive variations.
They are left for backup lines while the authors' recommendation goes for the most challenging options.
"Currently I do not see any serious theoretical problems for Black" claims Kolev in the foreword. In the Rossolimo the authors also share completely new ideas, developed by them.
