This book is nothing else than an absolute horror for every Grunfeld player.

– Martin Rieger, Schachwelt

Kaufman's work is rigorous and he has been able to find a significant number of improvements that should give food for thought for players of either color. The book lives up to the title and, yes, unless one is prepared accordingly, the knowledge therein could sabotage many a Grunfeld.

– Grandmaster Glenn Flear, author of Starting Out: Open Games

Kaufman gives a lot of attention to his explanations. In many cases these comments are not very long, but quite to-the-point. An extraordinary book.

– Uwe Bekemann, German Correspondence Chess Federation

An extremely solid opening repertoire, supported by powerful software; but of course Kaufman also regularly gives his own opinion on critical positions, an opinion that not always is the same as the one given by Komodo!

– Dr. W. Schweitzer, Rochade Europa Magazine

The analysis is unbiased and comprehensive, and Kaufman tends to provide enough verbal guidance to assist his non-master readers. Players looking for a new weapon against the Indian Defences would do well to consider buying this book.

– John Hartmann, British Chess Magazine

This move (3.f3) has been very topical against the Grunfeld at elite level in recent years and the American GM presents a compelling case for taking it up.
