Chess

Arms race

Raymond Keene

Top class chess is so fiercely competitive, and the impact of openings innovations can be so deadly, that anyone who possesses the most complete and up-to-date theoretical knowledge will have the chess equivalent of the latest thermo-nuclear device at his disposal. Such a weapon is provided by Grandmaster John Nunn's Sicilian Defence: Najdorf Variation (Batsford £7.95), which covers all varia- tions in the combative line commencing 1 e4 e 2 Nf3 d6 3 d4 cxd4 4 Nxd4 Nf6 5 Nc3 a6. The most intense examination, however, is devoted to the super-sharp Polugaievsky and Poisoned Pawn lines, occurring after 6 Bg5 e6 7 f4 b5 and 7 ... Qb6 respectively. There is a minimum of explanation, since John has concentrated on giving masses of moves as the most effective method of teaching the opening, and this is certainly a volume which demands a tremendous amount of memory work from the reader. Although the cover advertises joint author- ship by Nunn and Stean, this is very much John's own book for, as the author ex-

plains in the preface, very little (four pages) remains of Stean's original text from 1976.

Another excellent book which, however, does not fit into the previous category is the BCM's reprint of 1948 World Champion- ship by Harry Golombek (£7.25). A phenomenally strong tournament, compris- ing Botvinnik, Smyslov, Reshevsky, Keres and Euwe, it was designed to find a worthy world champion after the interregnum caused by Alekliine's death in 1946. Golombek's painstaking notes and full background colour combine to produce a model of what a tournament book should be, and, along with Harry's books of Reti's and Capablanca's best games, it forms a trilogy of all-time classic chess books. The books mentioned this week can be obtained from BCM, 9, Market St, St Leonards-on- Sea, Sussex.

Chess columns have been taking a knock recently, with the demise of Now! (Hart- -ston) and Tony Miles's successive disap- pearing acts from the New Statesman and The Listener. Good news, therefore, is Hartston's reincarnation in the new Mail on Sunday. Our favourite TV commentator makes no facile concessions to readers, since his material is highly topical and the notation the Fide-approved algebraic. In spite of a few early hiccups, such as por- tions of games missing, this looks likely to be an important and widely read addition to chess journalism in Britain.
