John Watson writes some really good books, but this one isn’t one of them! It’s not just for kids either; it should be for any beginner, but I am afraid it won’t be any help at all.
Watson tries to give a simple guide on 50 common openings, allowing 2 pages per opening, and explain the basic ideas of each one.
Some reviewers complained Watson’s language was too complicated for kids and that it might have been better had he used easier language and longer explanations. I am not sure I agree that it’s too difficult for kids to follow his prose because chessplaying kids are pretty smart but that aside, the basic explanations are not much help; in fact, for beginners, it’s pretty much useless.
One reviewer said the book is very hard to follow and I agree that the layout is somewhat confusing for a beginner and that’s what this book essentially is…an introduction to the very basic ideas of each of the openings designed for beginners, adults or children. If you are past the beginner stage you’ll likely not have any trouble following the layout, but if that’s the case, you are too advanced for this book. On the other hand, if you are a beginner you won’t understand why "black is in a dangerous situation" because Watson won’t tell you why. All-in-all, not a good buy for anybody.
