Although I haven't completed this yet, and I'm probably not strong enough to fully grasp some of the concepts within it, I have to say that this bears all the hallmarks of another classic chess book. Following on from his Secrets of Modern Chess Strategy, a book I constantly refer to and constantly learn from, Watson appears to be more relaxed in his writing of this book, as though he has given us most of what he has to offer but is now triumphantly demonstrating to us that he really does understand this game extremely well, and is eager to share that understanding, indeed driven to, it seems, for his enthusiasm is obvious to the reader. A structural difference to this book is the large section at the end of it containing annotated games that show what Watson is trying to make us see; I prefer this to the game fragments that are a necessary device in the rest of this book and so many others, if only for the ease of use when following the game on a board, and not having to set up the position. It also seems to round out the book well; it feels as though you not only have a marvellously instructive book, you also have a great games collection too. I'm sure stronger players than I will do this book more justice in their own reviews of it, but I'm convinced that it's destined to become an important work that all 'serious' (club-level and above?) players could learn from. One caveat - it probably won't be too useful to players below, say, 1500, although as with all rules there will be exceptions to this. (And that pretty much is a cornerstone of what Watson is trying to teach us about rules and dogmatism in chess, too....). Read, learn & enjoy.
