Like Lars Bo Hansen's third book "How Chess Games Are Won Or Lost," this is not a book for everybody, and therefore it won't please everybody. But it is right for it's target audience. And if that's you, then any critism is irrelevent. The target audience are players of approximately USCF 1350-1650 playing strength, or players up to USCF 1850 who know little about chess history, but WANT to know more. This is the ultra user-friendly book on chess history that so many players never had. It reads much better as an experience to ENJOY, and not on worrying about whether it is improving your play.
One key aspect to point out is that while this book discusses players and schools of thought, the author frequently shows many of his own games that were influenced by the players or concepts he discusses, showing its relevence to practical play.
Chapter 1 covers the Romantic Era. It shows that Morphy was, and still is, the master of the open center. Before I became a strong player I disregarded chess before Lasker. And I didn't understand why Botvinnik took Morphy and the open center seriously. After reading a book on pawn centers, I do now. The open center is where you learn to play hardcore tactics, sacrifice, quick development, initiative, and outright attack. Studying Morphy teaches you what to do when playing an attacker who is masterful at opening up the center: attack him before he attacks you! Many strong players ignore Morphy, but it only handicaps them. Lars Bo Hansen compares the open center of the Romantic era, to the more refined open center of today. I commend him for showing that it is still relevant. And yes, there is a nice juicy open center Kasparov game, among many others. So one is to be advised NOT to skip the more important parts of this chapter.
Chapter 2 covers Steinitz through Botvinnik, except for the Hypermoderns. I had always heard of Steinitz's theories but never actually got to read them. With this book, it was all laid out crystal clear without reading some outdated, excessively illustrated material. It could be pointed out that understanding this doesn't improve your chess. But it did deeply influence Lasker, Capablanca, and others of that period, and will help you understand them.
There is a section on Lasker and how he understood that if a weakness can't be exploited, it's not a weakness. He won games because his oppenents were waisting time trying to exploit weaknesses that looked exploitable but could not be exploited against his accurate, tenacious, resourceful defence. The section on Capablanca showed that he was the master of transforming positional advantages into material (usually just one pawn) and transforming that into a win. The section on Alekhine was good, showing how dynamism confused the positional chess players. Capablanca didn't quite understand that when he took advantage of Alekhine's innocent looking mistakes he wasn't holding a clear advantage--it was an imbalanced trade-off. Alekhine in return recieved his own definite but quite difficult to evaluate set of advantages. But the key was that he knew how to use them.
Chapter 3 is on Hypermodernism. Now you can understand "My System" without having to read a confusingly written and excessively long book. Early in my chess development my chess couch advised against learning chess strategy from "My System" because it has a hypermodern bias. So I read Ludek Pachman's 3 volume "Complete Chess Strategy" series, which was much better. But I never got to understand Nimzowitch's theories in detail. And it consists of a great deal of valuable information. But through this chapter I got to learn the the aspects that were relevent with unparalled clarity.
Chapter 4 is about Dynamism, mainly Tal and Keres. I knew about Tal, but I didn't know as much as Keres as I should have. Now I do. Both would run with the initiative beyond insanity, and win. It's a shame that this book only breezes through Bronstein and Boleslavsky, and the Soviet School's development of the King's Indian, Grunfeld, Modern Benoni, and open Sicilians (Najdorf, Scheveningen, Dragon, Marcozy, Sveshnikov, Kalashnikov, etc.)
Chapter 5 is about the Universal age. Starting in the 1970's, chess became a blend all previous styles. Its leaders were Fisher, Spassky, Karpov, and Larsen. I didn't realize Karpov was closer to Fisher in generation than to Kasparov. Also, I didn't know as much about Larsen as I should have, and I do now. He was a great attacking player who loved the initiative, with the universal style as discussed.
Chapter 7 is about chess in the future. Lars Bo Hansen makes a lot of predictions, but they are vague. It's a very interesting chapter however. The general premise is that chess is becoming more about preparation, training, and memory rather than true talent like in the days of Morphy, Lasker, and Capablanca. That basically chess is becoming more of a science. I really wanted a lot more of it.
My only complaints are that this book is only 192 pages, and that most of the players recieve only 4, and sometimes less, example games to illustrate their style. This is however counterbalanced by the generous proportions of high quality writing. I'm left wishing that it was 350 pages, more advanced, having more players, more games, and more information in general. Then it would be an instant classic for all players. But because of its lightness, it's an extremely well written not-too-difficult introduction to chess history for the improving class player.
