"Play the Nimzo-Indian" is one of the newest offerings from Everyman Chess, one of the top publishers of chess books in the English language. It is written by a young Scottish IM, Edward Dearing, who is perhaps best known for his previous book "Play the Sicilian Dragon," a book which received almost unanimous praise from reviewers (with the exception of GM Sergey Tiviakov, who strongly criticized it in New In Chess Yearbook 75). Dearing is quickly establishing himself as one of the more conscientious and instructive writers of books about chess openings.
"Play the Nimzo-Indian" is a repertoire book for the player of the Black pieces. It is important note that the Nimzo-Indian arises after 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4, and this book only provides a repertoire for Black from that position. Black players taking up the Nimzo-Indian as a defense to 1.d4 for the first time will also need to come up with a repertoire against the other major third move alternative, 3.Nf3 (the Queen's Indian, Bogo-Indian and Modern Benoni are three possibilities), and against less theoretically challenging deviations (the Torre Attack, Trompovsky, Colle System, London System, Veresov, etc.). However, the Nimzo-Indian itself is a huge subject, and it seems to me that it is correct to cover a Nimzo-Indian repertoire in a separate book. As a caveat to this review, I should note that I don't presently play the Nimzo-Indian with the Black pieces myself, although it was my first defense to 1.d4 and as a 1.d4 player I have played various lines against it over the years, so I have some familiarity with it.
"Play the Nimzo-Indian" is in Everyman's usual "complete games" format, in which the author uses complete games to demonstrate and explain the critical lines in the repertoire. I consider this format to be optimal for players learning a new opening, because including complete games allows the player to study typical middlegames and endgames arising from the opening as well as the opening theory. There are 50 main games in this book, which is perhaps close to the average number for an Everyman opening book. However, this book is a substantial 224 pages in length, well above average for an Everyman production. The extra pages result from a greater than usual amount of analytical sidelines and explanatory material in the text.
There are several features in this book that I consider to be improvements on Everyman's traditional "complete games" format. First, there is a two-page index of variations in the back which I don't recall seeing in previous Everyman books but which is extremely useful for quickly locating games played in specific lines. Everyman has received some criticism in the past for not having an index of variations and finally seem to have done something about it.
Second, and perhaps more significantly, after each of the 50 main annotated games there is a short (anywhere from a paragraph to almost a full page in length) "Conclusions" section (e.g., "Game 1 Conclusions," "Game 2 Conclusions," etc.) which discusses the theoretical significance of the preceding game, lessons to drawn, and often notes typical middlegame maneuvers/themes/ideas. I found these sections, notwithstanding their brevity, to be very useful in helping me assimilate the games and place them in their proper theoretical context. This is a very welcome innovation from Dearing and I hope Everyman considers making it standard in their future opening books in the "complete games" format.
As for the theory and games presented, the Nimzo-Indian is a sound and dynamic defense to 1.d4 that has been played by virtually every World Champion of the last 50 years and the majority of the world's top players in that period as well. It is extremely solid while presenting opportunities to play for a win with Black against all levels of opposition. Because there are so many viable subvariations in this opening, Dearing has had a wealth of lines from which to chose his repertoire, and in general I think he has done an excellent job in making his selections. Of course, the selection of which subvariation to play in a major defense like the Nimzo-Indian involves issues pertaining to personal style and preference, and not everyone will be happy with every one of Dearing's choices. However, the richness of the Nimzo-Indian is such that you will always have a number of alternatives if you don't like a specific variation chosen by Dearing. And overall I think Dearing has done a good job of presenting a repertoire that will appeal to a broad spectrum of players.
"Play the Nimzo-Indian" presents a Nimzo-Indian repertoire that will be playable (and is played) at virtually any level, from the club player to the super-GM. This is not the kind of "quick fix" repertoire often presented by lazy or dishonest authors and intended for weaker players who want an easy solution to their opening problems. The players of the Black pieces in the annotated main games include such famous GMs as Karpov, Anand, Korchnoi, Ivanchuk, Gelfand, Short, Bareev, Adams and Khalifman. In general, Dearing presents a very serious, even ambitious, repertoire, and chances are good that the main repertoire choices by Dearing will remain playable for the rest of your chess career.
The downside of choosing a really sound opening repertoire is that there is usually quite a bit of theory involved, as sound lines are popular with good players. Dearing has done a very reasonable job of limiting the amount of theory presented, often by choosing slightly less theory-intensive but very sound alternatives to the absolute main lines. That having been said, presenting a serious Nimzo-Indian repertoire is not a trivial task, and notwithstanding the "complete games" format this book has a lot of theory packed into its 224 pages. Because of the amount of theory, I would primarily recommend this book for ambitious players willing to do a certain amount of work to prepare a sound opening that will last them for a lifetime. Due to the wealth of explanatory material, I think that most of the book would be accessible to players above 1800 elo, although ambitious lower-rated players might find much that is useful and enlightening here.
I give this book 5 stars. In the genre of opening books in the "complete games" format, it is one of the two or three best that I have seen.
