SIMPSON'S

IN-THE-STRAND

KASPAROV'S performances in the two super-tournaments at Las Palmas and Linares must rank amongst the very finest in the history of chess. Preliminary calcula- tions indicate that together these two tour- nament victories will have catapulted his rating to a new world record of 2820 on the international scale. If one considers that 2500 is grandmaster level and 2700 indi- cates a likely candidate for the world cham- pionship then Kasparov is all the more remarkable in that he is the only player since the system was introduced ever to have smashed the 2800 barrier.

Kasparov achieves his astonishing effects by a mixture of extreme openings erudition and fearless resolve in entering and pursu- ing the most hideous complications. The rewards are obvious: many victories where other strong players would have been con- tent with draws. Naturally, though, such extremism invites the occasional loss. What is surprising is that, given the immense risks he runs, Kasparov loses so few games. At Las Palmas and Linares, playing exclu- sively against the world's elite, Kasparov lost just one game, a frightful battle on the edge of a cliff in which he finally missed his footing. This game, however, shows the mental terror anyone must go through before landing a decisive hit on Kasparov.

1 d4 Nf6 2 c4 g6 3 Nc3 Bg7 4 e4 d6 As usual, Kasparov resorts to his favourite King's Indian Defence. This is a double-edged line, in which Black surrenders much of the central territory to White's pawns in order to engineer undermining blows on the flank. 5 f3 0-0 6 Bg5 Ivanchuk's choice, 5 f3, constitutes the popular Saemisch Variation and 6 Bg5 has been in the ascendant steadily over the past few years as a less hack-
