Exploding with wins in the last three games, Garry Kasparov triumphed last week in Sarajevo, Bosnia, proving that he is this year's most brilliant tournament player. The final standing: Kasparov, 7 points in 9 games; Alexei Shirov and Evgeny Bareev, 6 each; Alexander Morozevich, 5.5; Michael Adams, 5; Peter Leko, 4.5; Veselin Topalov, 4; Nigel Short, 3; Ivan Sokolov, 2.5; Jan Timman, 1.5 points.

In the last round against Adams, Kasparov improved on the Scotch game (Ljubojevic vs. Spassky) played 20 years ago in Montreal.

Kasparov-Adams

1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Nf6 5.Nxc6 bxc6 6.e5 Qe7 7.Qe2 Nd5 8.c4 Nb6 9.Nc3 Qe6 (We all asked in Montreal whether black could grab a pawn after 9...Ba6 10.Qe4 Qb4?! 11.a3 Qb3 12.Bd3 ? Of course, 12...Bxc4? fails to 13.Bc2 trapping the queen, but 12...Nxc4 led to fairy tales after 13.0-0 Nxb2 14.Bxa6 Qxc3 15.Ra2 Rb8, where the pinning 16.Qb1 Bxa3 17.Qa1 Rb3 did not seem to work to white's advantage. Better is 16.Bxb2 Rxb2 17.Rxb2 Qxb2 18.Rb1 and white has serious winning chances. For example, 18...Qxa3 19.Qh4! f6 20.Rb8+ Ke7 21.exf6+ gxf6 22.Qe4+ Kf7 [22...Kd6 23.Re8 creates a mating net.] 23.Qe8+ Kg8 24.Bc4+ d5 25.Rb3 Qc1+ 26.Bf1 and black is defenseless against 27.Rg3+.)

10.Qe4 Bb4 11.Bd2 Ba6 12.b3 Bxc3 13.Bxc3 d5 14.Qh4!? (A new idea. The queen looks after two squares c4 and d8. Ljubojevic played 14.Qf3.) 14...dxc4 15.Be2 Nd5 (Hoping to create some play against the white king in the middle.) 16.Bd4c5?! (There was an argument for 16...Nb4.) 17.Bxc5 Nc3 18.Bxc4 Qxe5+ 19.Be3 Ne4 20.0-0 Bxc4 21.bxc4 0-0 22.Rfe1 (Kasparov goes after the unstable knight, also targeting the weak pawn islands on the queenside.) 22...Rfe8 23.f3 Nd6 (White has the edge after either 23...Nc3 24.Qf2; or after 23...Nf6 24.Bxa7.)

24.Bf2 (Now 24.Bxa7 is met by 24...Qc3.) 24...Qf5 (It is not easy to find a good square for the queen where it would not interfere with its own knight.) 25.c5 Nb5 (An awkward place for the knight, but after 25...Rxe1+ 26.Rxe1 Ne8 27.Qa4 white's active pieces dominate the board.) 26.Qb4 Qd3 (The knight is lost after 26...Qd7 27.a4. After 26...c6 27.a4 Nc7 28.Qb7 is unpleasant for black.) 27.Red1 a5 28.Qa4 Qe2 29.Re1 Qd3? (Overloading the queen loses outright. Better was 29...Nc3, although after 30.Qc6 Qb5 31.Rxe8+ Rxe8 32.Qxc7 white's c-pawn is dangerous.) 30.Rxe8+ Rxe8 31.Rd1 (After 31...Qe2 32.Re1 wins.) Black resigned.

Adams played one of the best games in Sarajevo against Sokolov, using beautiful geometrical motives along the 6th rank to break into black's fortress.

Adams-Sokolov

1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d6 6.g4 h6 7.h3 a6 8.Bg2 g5 9.Be3 Nbd7 10.Qe2 Ne5 11.0-0-0 (While securing the square e5, black makes too many pawn moves, giving white the lead in development.) 11...Bd7 12.Nf3! (Black cannot support his centrally placed knight with his other knight, because the square d7 is taken away by the bishop.) 12...Qa5 13.Kb1 Be714.Nxe5 dxe5 (Black pawns control a lot of central squares, but the king is not safe.)

15.h4! Rg8 (After 15...gxh4 16.Rxh4 Nxe4?! 17.Nxe4 Bxh4 18.g5 Bxg5 19.Nd6+ Ke7 20.Qh5 Be8 21.Nxb7 Qc7 22.Bxg5+ f6 23.Bxf6+ Kxf6 24.Qh4+ Kg7 25.Nc5 Qxc5 26.Bxa8, white's attack breaks through.) 16.hxg5 hxg5 17.Rh6 Bc6 18.Qf3 Nd7 19.Rh7 (Just teasing and winning time.) 19...Nf6 20.Rh6 (The rook is x-raying the 6th rank.) 20...Nd7

21.Bf1! (Finding the optimal squares for his pieces is Adams's trademark. The bishop aims for the square c4 and black cannot do much about it.) 21...Rd8 (The geometrical idea comes alive after 21...b5 22.Nd5!, for example after 22...exd5 23.Rxc6 d4 24.Bd2 black is languishing on the white squares; or after 22...Bf8? 23.Bb6! Nxb6 24.Nc7+ Ke7 25.Qf6 mate.) 22.Bc4 Nf8 (After 22...b5 23.Bd5! exd5 24.Rxc6 d4 25.Nd5 dxe3 26.Rxa6! white wins the queen, e.g. 26...Qxa6 27.Nc7+)

23.Nd5!! (A genuine piece sacrifice, opening lines and diagonals to the king.) 23...exd5 24.exd5 Qb4 (After 24...Bd7 25.d6 opens the road to f7. On 24...Bb5 comes 25.Bb6.) 25.dxc6 Rxd1+ (On 25...Qxc4 comes 26.b3.) 26.Qxd1 Qxc4 27.b3! Qb4 28.a3! Qa5 (The queen is being deflected from crucial squares, e.g. 28...Qxa3 29.c7 and white queens. On 28...Qb5 comes 29.c4.) 29.cxb7 Nd7 (After 29...Qc7 30.Qd5 Nd7 31.Ba7 Kf8 32.Rxa6 Rh8 33.b8Q+ Nxb8 34.Bxb8 white wins.) 30.Rc6 (Another pretty win was possible with 30.Bb6!, e.g. 30...Qc3 31.Rd6!! Bxd6 32.Qxd6, threatening 33.b8Q+ Nxb8 34.Qd8 mate; or after 30...Qxa3 31.Rc6! wins.) 30...Bd8 31.Rc8 (Or 31.Rc5 Nxc5 32.b8Q Ne4 33.Qd3 winning.) 31...Ke7 32.Bc5+ (After 32...Ke8 33.Qd6, threatening 34.Qe7 mate, white wins.) Black resigned.
