When Boris Avrukh released his 1.d4 repertoire books in 2008 and 2010, they caused a sensation. Volume 2A is the third out of four brand new volumes in which Avrukh revamps, expands and generally improves upon his previous work in every way possible. This book provides a world-class repertoire against the Gruenfeld and King’s Indian, two of Black’s most popular and dynamic defences. The author remains faithful to his preferred Fianchetto System, but has completely re-analysed it to forge an even more effective repertoire weapon than before. Boris Avrukh is a grandmaster from Israel. He is an Olympiad gold medallist, former World Junior Champion and analysis partner of World Championship finalists.
