This book is a completely new edition of the original The Safest Grünfeld of 2011. I rechecked all the lines and changed my recommendations according to latest developments of theory and my new understanding. 

Especially the anti-Grünfeld chapters are basically new. In my opinion top players have long lost hope to find advantage in the main lines and try early deviations. Anand chose 3.f3 against Gelfand and 5.Bd2 against Carlsen. So I devoted special attention to the Sämish approach with two different propositions. 3...Nc6 is less studied and probably more rewarding from a practical standpoint, while 3...d5 is in perfect theoretical shape, but requires more memorization. 

Every too often White players try to avoid the Grünfeld by refraining from d4 or c4. I added an additional chapter on the very topical lately Trompowsky and Barry/Jobava attack. The 7.Bc4 system in the Exchange Variation, and the Russian System have also underwent a major reconstruction.
