The fifth in Kasparov's series on the world champions (and their greatest rivals) focuses on Anatoly Karpov, Kasparov's immediate predecessor and greatest rival, and Karpov's own bete noire, the great defector, Viktor Korchnoi.
Korchnoi and Karpov pose interesting challenges compared to Bobby Fischer, the main subject of Vol. 4 in the series. For starters, each has played well over 3,000 "official" games, compared to fewer than 800 for Fischer! Second, they are probably of less interest to Western readers than Fischer. But that is the readers' loss, for both are fascinating characters, as well as great chessplayers. Their world championship match in 1978 in Baguio, the Phillipines, was surely one of the bitterest, as well as most bizarre, encounters in the history of chess. Moreoever, in contrast to Fischer, who took long absences from competition and stopped playing altogether at the age of 29, both have maintained their strong play over decades.
Kasparov seems to have done a competent job showing the competitions and controversies of both men, including the manuverings that led FIDE to strip Fischer of the title and award it to Karpov, Korchnoi's 1976 defection and the subsequent "boycott" of him by the Soviet players, Karpov and Korchnoi's emergence as the leading players after Fischer's disappearance, and the eclipse of the former champion, Boris Spassky.
But the critical aspect of a book like this is the annotations. As with Vol. 4, I think the verdict is that they are excellent, with some reservations. Looking at the annotations for one of Karpov's famous wins, Karpov-Timman, Montreal 1979, I think some of the criticisms that have been made of earlier volumes still hold good -- he (or his assistant Plisetsky) relies heavily on earlier analysis by Dvoretsky and Karpov, adding what looks like a lot of Fritz-analysis to the opening. (That said, it's a great game, and Dvoretsky's and Karpov's comments are fascinating.) Turning to the analysis of some of the games from the Karpov-Spassky match in 1974, however, Kasparov's hand is much more apparent. The analysis of Game 3 -- Karpov's first victory after an opening-game defeat -- is tremendous, not just in terms of variations but in the first-rate explanation of both sides' strategic plans. I hope the rest of the analysis in the book is more like Karpov-Spassky than Karpov-Timman, but either way I am very glad to have the book.
