Final spurt

Raymond Keene

Two weeks ago I published Karpov's loss • to Ljubojevic from the super- tournament at Turin. It seemed then that the world champion was heading for another mediocre performance, along the lines of his setback at Mar del Plata earlier in the year. Nevertheless, Karpov succeeded in staging a rally and, aided by good for- tune, he eventually tied for first place with Ulf Andersson, the same result as in the Phillips and Drew tournament at London in April.

(Games in brackets lost by default.)

In comparison with Kasparov's dominating form at Bugojno Karpov's re-

cent tournaments have been unimpressive. In fact, the games he won at both London and Turin have been limited almost solely to those where he has had White against the Sicilian. Paradoxically, Karpov's over- whelming defeat of Korchnoi at Merano may have undermined his desire to succeed. fie has certainly displayed some notable feats of willpower in his last two tour- naments, but only to recover from situa- tions where he has fallen behind. Kasparov, on the other hand, has devoted his energies to capturing first prize by the widest possi- ble margin.

The table reveals the kind of luck from which Karpov benefited. First of all, there were very few decisive games, so Karpov did not have to over-strain in order to catch up.

Then the early leader, Hubner, withdrew due to illness and defaulted all of his games in the second cycle. Withdrawal symptoms have, unfortunately, become all too prevalent with the talented German, and it looks as if his nerves or health will prevent him from reaching the very top.

Here. is the game in which Karpov simultaneously gained his revenge and caught up to the joint lead.
