This book does not waste time on the rules of the game but this shouldn't really be expected after you've read the title. If you've been playing a little while and are heading up past the 1300's or 1400's level then you will probably hit a wall around this area and find yourself wondering how to improve some more. This book is an excellent tool to help you. Through each chapter the text explains the tactical and strategic ideas that you will have to learn and there are just enough diagrams to make it comprehensible. It is worth a slow, careful reading, practicing what you read as you go, as some of the later chapters seem to be addressing a more advanced player than one who first opens the book. This book should be in every club players bookshelf and will be a valued addition to it. As the author notes, the negative notes about adjourned games is a bit of an anachronism as such games are more often now decided by blitz time limits rather than meeting some other time. I have 20 books on chess so far, I cant think of any I have which cost less but I'd say this is the most valuable to me. What are you waiting for?
