In my chess tournament career, I have never played 1... d6 as black. I bought this book primarily because I found it somewhat annoying to play against as white, especially in blitz games. I have also liked the other books I have read in Everyman's "move by move" openings series, so I had high expectations for this book, which have fortunately been met.
As the author states, his "true chess nature is that of an initiative-challenged chess dullard." In that spirit, this book and black opening repertoire is directed more at those players of a positional rather than tactical bent, recognizing that in any opening there will be lines that lead to more tactical than positional treatments.
I like the Q&A format, and the true measure of my appreciation for the book is that I am seriously considering changing my own black opening repertoire to include 1...d6. I have to admit, though, that although I have skimmed through the whole book, my thorough reading has taken me through only 1/3 of the book so far.
One small complaint is that sometimes he talks down to the reader, with comments such as "White always enters this line expecting something for nothing. With this sense of entitlement..." But this does not seriously detract from the enjoyment or educational value of this book.
Few of the games in the book that are used to illustrate the opening ideas are games of the top grandmasters. This is probably due in large part to the nature of the opening, which isn't particulary popular at the very highest levels. Also, the author at times seems to be a little biased towards black in his analysis, a not uncommon trait in a repertoire book. Nevertheless, I heartily recommend this book to chess players who are looking at this opening from either side of the board, especially players who are unfamiliar with this opening, and players rated below about 2300.
