Power Chess: Great Grandmaster Battles from Russia, by Paul Keres, Edited by Burt Hochberg, 1991 David McKay Co., Inc., English Algebraic Notation, Softcover, 281 pp., $14.00 The late 1960s and first half of the 1970s was one of the most exciting and dynamic periods in the chess world. Fischer ended his self-imposed exile from the game and re-emerged with a series of tournament and match triumphs that culminated in his winning the world title in 1972. New names began to appear in tournament crosstables, names such as Timman, Mecking and Ljubojevic. In the United States, the relatively small chess federation was about to experience an upheaval that would result in an increase in membership - of approximately tenfold - driven most by "Fischer frenzy". The official magazine of the U.S. Chess Federation, "Chess Life", would also undergo a startling transformation. Under the guiding hand of its new editor, Burt Hochberg, it would go from a small publication of uneven quality, never quite appearing on time, to a major, world-class magazine with some of the best known names in the chess world writing in its pages. One of those writers was the Estonian (then Soviet) grandmaster Paul Keres. There has been much speculation, at The Chess Caf‚ and in other chess journals, about Keres' relationship with Botvinnik, particularly in the 1948 championship tournament. One thing is not disputed by anyone, however: Keres was one of the greatest players of his era, often called the greatest player never to become world champion. This world-class grandmaster was also a world-class annotator. As Hochberg points out in his Introduction, "Keres had the rare ability to make grandmaster chess comprehensible... A game annotated by Keres is like an adventure story in which the connections between all the characters and all the events can be clearly seen and understood." In 1967, Hochberg was able to convince Keres to write a regular column for Chess Life. When his first article appeared in the January, 1968 issue of the magazine, Keres became the first Soviet grandmaster to conduct a regular column in an American chess magazine. Power Chess is a collection of 22 of the most dramatic and instructive chess struggles played in that period. These are divided into three basic sections: Kingside Crushes, Middlegame Masterpieces and Endgames under the Microscope. These are the cream of the 40 articles by Keres that appeared in Chess Life. Normally we would present, as part of a review, a complete game with annotations, selected so that the reader can get a good feel for the book. In this case, that approach is not practical. The annotations are so deep and extensive that presenting even one game would be much too long. Each game, however, is also introduced by a brief narrative. Of particular interest is the one to Game 13. Entitled "Inspiration or Preparation?", it features the game Bronstein vs. Ljubojevic, an Alekhine's Defense from the Interzonal Tournament held in Petropolis, 1973. It was written over 25 years ago... If I were asked to name the most prolific modern grandmaster in terms of innovative ideas, I would name neither Fischer, Spassky, Larsen, nor Petrosian, but ... Bronstein! I speak of new ideas and variations not only on the chessboard but in many other aspects of the game as well. Among Bronstein's myriad suggestions for making chess more lively and interesting are: recording the time used for each move; allowing each player half an hour to finish the game after the first time control; limiting the time for an entire game to one hour; setting up national cup competitions in the form of short matches (the first U.S.S.R. Cup was held in 1970 and was won by Bronstein!); and many others. His latest suggestion concerns world championship contests. We already have the World Junior Championship, the World Student Team Championship, men's and women's individual titles, men's and women's team titles (the Olympiads) ... so why not the World Senior Championship? asks Bronstein. His idea is to hold a tournament to which would be invited all grandmasters over the age of fifty who have participated in at least one Candidates' tournament (or match). This proposal has its logic, and perhaps FIDE will deal with it at one of its congresses. But Bronstein's most interesting and valuable ideas are still produced on the chessboard. I had the pleasure of watching him play at the Interzonal tournament in Petropolis, where among his many magnificent battles his brilliant game against Ljubo-jevic deserves special mention. Bronstein's rook sacrifice on move sixteen was a tremendous surprise, and during the game it took me quite a while to find the point of it. No wonder this is considered the most beautiful game of the tournament. At the time I was not sure whether the sacrifice was an improvisation or had been carefully prepared at home. I'm still not sure. Up to move fourteen the players repeated a game between Ljubojevic and Honfi at Cacak 1971. That game was a quick victory for Ljubojevic, who played White. Here against Bron-stein he was playing the same variation, but as Black, having in mind an improvement on the fourteenth move. It is that improvement that led to Bronstein's wonderful rook sacrifice two moves later. Could it have been prepared by Bronstein at home? His sacrifice recalls his famous game with Tal in Riga 1968 [Game 4 in this volume]. He explained his rook sacrifice in that game by saying he "could not miss the opportunity" to play such a move against Tal, an opportunity he might never have again in his whole life. Knowing Bronstein, it's my guess that his sacrifice in this game, too, was an inspiration of the moment - to make the game more interesting, more complicated, more distinct from other games. In any case, it is a wonderful fighting game and one of the most interesting grandmaster encounters of recent years... If you belong to the "post-Fischer" chessplaying generation, it is possible that you did not experience Keres' wonderful Chess Life columns. Even if you are familiar with them, this collection will stsill delight you. In short, Power Chess deserves to take its place among the outstanding chess books of our time. Combining deep analysis with interesting, insightful writing, it belongs on the bookshelf of every chessplayer.
