THE INDIAN GRANDMASTER Viswa- nathan Anand finally broke through in game 9 to take the lead in his match in the PCA qualifying cycle against Gata Kamsky. There had been a long previous sequence of draws but during this arid period it was always Anand who seemed to be on the verge of a win. Kamsky's normally impec- cable preparation had seriously stalled, and he was notably lacking in the energy which had characterised his sequence of match triumphs against Kramnik, Short and Salov. That said, Kamsky recovered after a disastrous start and went on to win against Anand in their Fide match last year so, in spite of his currently precarious situation, his prospects cannot, as yet, be entirely written off.

the board Kamsky's treatment now seems much too slow. 16 b3 g6 17 Bb2 Bg7 18 Qcl At first sight a strange move, but it is the initial link in a plan to embarrass both black knights. The long- range intention is to proceed with Bc3 followed by Qb2, with veiled threats against the black knights on b4 and f6. 18 Rac8 19 Bc3 c5 20 d5 Qe7 21 Nfl Nh7 Already an admission of strate- gic defeat. Once the dark-squared bishops are exchanged, definite holes appear in the fortifica- tions around the black king. 22 Bxg7 Kxg7 23 Ne3 Black's bishop on b7 is locked out of play and meanwhile White threatens unpleasant tac- tics against the black king commencing with Ng4. This provokes further weaknesses in the black king's field. 23 ... h5 24 Qd2 Kg8 25 axb5 axb5 26 Ndl Na6 27 Nei b4 28 Nb5 Nc7 29 Bd3 NxbS 30 Bxb5 Red8 31 Bc4 Nf6 32 bh6 QM 33 Qg5 (Diagram) Anand's feints against the black king have caused Kamsky's queenside defences to be depleted. White now takes advantage of this to force a decisive invasion via the 'a' file. Nevertheless, if Black decides to contest the invasion on the queen's flank by means of 33 ...Nh7 34 Qf4 Ra8 then 35 Rxa8 Rxa8 36 e5 dxe5 37 Nxe5 grants White a huge attack with moves like d6 to follow, unmasking a devastating battery against Black's pawn on f7.33 ...

In Linares, which had been played in parallel to the first half of the Kamsky match, Ivanchuk triumphed a point ahead of Karpov. Nigel Short's performance was not one of his best but he was awarded a brilliancy prize for the following drastic miniature.
