In this book, English GM John Nunn reviews 100 of the most important chess ideas and provides four examples for each of them, discussing the positions and how best to proceed. There's a lot of chess wisdom here which, if studied, will become part of your arsenal when playing competitive chess. John Nunn has the ability to explain things, even complex concepts, in a manner that is clear and simple to understand. I wish there had been such a book when I first fell in love with the game of chess and only had Reuben Fine's "Basic Chess Endings", a magnificent reference work which is difficult to take in when you're trying to learn chess endings from the ground up. Nunn's book makes the study of chess endgames enjoyable with his many examples. Most are drawn from current praxis but there are many examples from the last 150 years of masterly play. In fact, all levels of chess players could benefit from this book.
