''Grandmaster Repertoire'' is a new series of high quality chess books based on the main lines, written by strong grandmasters. The aim is to provide the reader with a complete repertoire at a level good enough for elite tournaments, and certainly also for the club championship. Grandmaster Repertoire provides a repertoire to last a lifetime. Top GM Boris Avrukh charts a course towards an advantage with 1.d4. Avrukh is used to facing the best players in the world. In this book he presents an improved version of the repertoire that elevated him to the top 50, focussing on main lines with a kingside fianchetto. Volume I covers the openings after 1.d4 d4 2.c4, particularly the Catalan, Queen's Gambit Accepted, Semi-Slav, Slav, and other Queen's Gambit lines. Volume II covers all Black's other answers to 1.d4.
