Master and amateur

The Road to Chess Mastery (Allen and Umvin 30s) by ex-world champion Professor Max Fuwe and Dr Walter Meiden of Ohio State University is more than just another book on how to play better. It is a serious and fascinating attempt to analyse the difference between a master and a strong amateur and, through the analyses, to enable the amateur to improve; the medium for the attempt is an exhaustive study—averaging ten pages a game—of twenty-five master v amateur games.

`Master' and 'amateur' are to a large extent relative and not absolute terms; each covers a wide spectrum of strength and this is recognised —at least in the case of the amateur—by a gradual increase through the series of games in the amateur's play, leading to his transmutation in games 21-25 from amateur to expert and his victory in the last three of his games. Nevertheless, there are various typical ways in which the master characteristically excels a strong amateur—and strong amateur is a term which would cover almost every- player in this country. The master has a more comprehensive knowledge and a deeper understanding (not the same thing) of the open- ings; he is far better in the very difficult transition from opening to middle game in which one is transforming the ideas of the opening into the strategic plans of the middle game; he is more creative—because, better than an equally gifted amateur, he understands the range of possibilities that exist in a position; he is more capable of a strategy embracing the whole of the board and not just a localised affair directed at a point of obvious weakness; he is far better at the defence of a difficult position—anyone who has ever got the upper hand against a great master will know how many defensive resources will be found and how hard it is to push such a situation to victory: he is greatly superior technically in the end. game.

All these points and others emerge in the games and the analyses of the twenty-five master v amateur games. The authors make you under stand—and I think one really does understand- why the amateur (or, in the last three games, the master) loses. Whether you want to improve your own game, or merely to understand why a master is a master, I can warmly recommend The Road to Chess Mastery. Next week I will give a game from the book.
