Grandmaster Repertoire is a 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.
In two volumes, The Grünfeld Defence offers a complete repertoire for Black against 1.d4. Avrukh's two previous Grandmaster Repertoire books White received universal rave reviews and have been hugely influential on chess players all over the world, including at the very highest level.
This is Volume One of Two.
