The first book on the Gruenfeld Indian was written by Grandmaster Pavlovic in 2016 and was well accepted. This new edition is significantly expanded (the 1st edition was 232 pages), and also deals in many cases with variants not included in the first edition. Most of these are modern continuations used in recent times. The second picture shows the contents of the book. Further information about the book and a sample are available at thinkerspublishing.com
