This book would bring something new into your chess library. In computer era focus is usually on openings. Watching broadcasts new generations rather choose games with favorite opening played seeking for some interesting idea or even brilliant novelty. I offer and recommend different concept, based on famous Soviet chess school. Focus should be on understanding strategy concepts, principles and inner logic. Fashionable opening lines will be forgotten (or re-evaluated) sooner or later, but understanding cannot be lost and can be only upgraded. It is sad to see some player well equipped with opening lines, unable to realize big positional advantage in deep endgame. So, our advice is to learn about Strategy and Logic. The book is highly recommended for club players, advanced players and masters, although even higher rated players can find a lot of useful things for themselves. There is no doubt lower rated players will learn a lot about thinking process and making decisions, while some logical principles can be good advice for strong players also.
