Dvoretsky - Le Manuel des Finales

Deux des plus forts joueurs de notre temps (je veux dire Kasparov et Fritz, puisque l'ex-champion du monde ne fait pas mystère d'utiliser abondamment l'aide de l'informatique) se penchent sur les accomplissements des champions du passé. Ce premier volume passe en revue un bon siècle de l'histoire du jeu, du premier championnat du monde officieux (McDonnell-La Bourdonnais 1834) à la mort d'Alekhine (1946), sautant bizarrement la parenthèse Euwe (1935-37) gardée pour le deuxième tome. Comme son titre et sa couverture l'indiquent, l'ouvrage se focalise sur les quatre champions du monde officiels, mais les auteurs prennent le temps de nous parler un peu de leurs principaux adversaires, avec tout de même quelques négligences regrettables (Maroczy représenté simplement par une fin de partie perdue...). Par la force des choses, les parties présentées (117, plus une trentaine d'extraits) sont en général archiconnues, mais elles ont bénéficié d'un travail d'annotation fouillé, utilisant tant l'oeuvre des commentateurs passés que les ressources de la technique moderne, esquissant ainsi une sorte de mise en perspective de l'histoire des échecs. Osons tout de même deux petites critiques (ce qui fera donc trois au total) à l'encontre de ce bel ouvrage : la mise en page un peu négligente, qui rend la lecture de certaines parties un peu laborieuse, et la présence d'une introduction superflue où Kasparov se répand en considérations politico-historiques passablement filandreuses - tout homme, quelle que soit son intelligence, devrait se cantonner à sa spécialité... Un dernier détail : comme le livre s'achève inévitablement par un rappel (honnête mais un peu édulcoré) des agissements d'Alekhine durant la Seconde Guerre Mondiale, signalons que l'historien Ken Whyld vient de rééditer une plaquette contenant les articles antisémites écrits pour le Pariser Zeitung, accompagnés d'une introduction faisant le point sur l'affaire (Alekhine Nazi Articles).

The second volume of Elk and Ruby’s treatise on Viktor Korchnoi, penned by FM Hans Renette and IM Tibor Karolyi, covers the period 1969-1980. This encompasses Korchnoi’s famous world championship fight with Karpov at Baguio City in 1978, his candidates final matches against Karpov in 1974 and Hubner in 1980, as well as the related candidates cycles and major tournament performances. Much biographical colour is supplied on his life and character, with this period including his defection from the Soviet Union to the West in 1976. Like in Volume I, original material is provided from interviews with key protagonists and their relatives, while sources in Russian, German, Dutch and Hungarian as well as English are used to paint the most comprehensive portrait of Korchnoi available.
140 games and fragments are analysed in detail in this work. As well as Karpov and Hubner, opponents include Fischer, Spassky, Petrosian, Smyslov, Portisch, Geller, Najdorf, Timman, Larsen, Mecking, Sosonko, Andersson, Ljubojevic, Polugaevsky, Nunn, and Miles among others. Many new discoveries are made in the analysis. In particular, the authors identify that Korchnoi worked hard to improve his endgame ability significantly during the time that he was boycotted in tournaments by the Soviets, which is most surprising given that he was in his mid-forties by then, and was the best player of his time at endgame tactics. Further, the authors found that his reputation as a pawn grabber was highly exaggerated, and that he carried out a huge number of king attacks on the h-file. They also discovered that Korchnoi more than matched Karpov for openings in the 1978 title bout despite the unprecedented preparation of the Soviet chess machine, and that the key reason he lost that match was time trouble.
The book is supplemented with a generous supply of photos, many taken from the Korchnoi family archive and never before published. 518 pages
