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 chess book provides a world-class repertoire against the Grünfeld and King’s Indian, two of Black’s most popular and dynamic defenses. The author remains faithful to his preferred Fianchetto System, but has completely re-analyzed it to forge an even more effective repertoire weapon than before.
