Photo © http://www.wccsanluis.net Round 4 1st October 2005 Viswanathan Anand's brutal win against Michael Adams in round three kept him level with Vesselin Topalov going into the round. The idea that the two pre-event favourites would battle it out for the championship took a knock in round 4. Anand never looked comfortable on the black side of a Najdorf against FIDE Champion Rustam Kasimdzhanov. Anand finally blundered badly on move 30 and Kasimdzhanov wrapped things up fairly efficiently. The 3rd favourite Peter Leko started the day in last place. He got the advantage quickly on the white side of a Sicilian Taimanov against Judit Polgar. Polgar quickly became dispirited and didn't put up much of a fight in a game that lasted 25 moves. Vesselin Topalov is prepared to go into positions with white which are not necessarily objectively favourable but which present complicated problems to his opponents. Around about move 25 it became clear he was somewhat better and by move 30 Adams lost the thread of the game and things went downhill fast, accelerated a little by the loss of the exchange on move 36. The final game to finish was that between Alexander Morozevich and Peter Svidler. The game started 1.d4 Nf6 2. c4 g6 3. f3! after which Svidler had a long thought trying to work out what Morozevich had in mind. Svidler eventually decided to go into a Saemisch Kings Indian instead of trying to take things into his usual Gruenfeld structure. Morozevich must have had somewhat the better of it for a while but its clear he comes into the event not in the best form or shape. By first time control Svidler was a pawn down but with all the chances and Morozevich crumbled in only 15 moves to a loss. Svidler has now moved into clear second place and has white against the leader Topalov on Monday. Rest day Sunday.

[30...b5 Looks like the way to go. 31.axb6 Qxb6+ 32.Kh1 Rdd6] 31.Qc7+?! Fortunately for white this doesn't spoil anything as he can repeat and find the better idea. [31.Bh5! Is an immediate win.] 31...Rf7 32.Qe5+ Rf6 [32...Kg8 Tryinf to avoid the repetition doesn't really help.] 33.Bh5!

White has nasty pressure all over the board but black perhaps still had chances to hold. [30...Qxb5] 31.Rxa7 Rxh5 32.e3 Qh2+ 33.Kf1 Qh3+ 34.Ke2 Re5 35.Rc7 Rc8?  Black was probably banking on this move but he has missed an important tactic. 36.Bf5! Interference wins the exchange and the game. 36...Rxf5 37.Rxc8+ Kh7 38.Rh1 1-0 Morozevich,A (2707) - Svidler,P (2738) [E81] WCh-FIDE San Luis ARG (4), 01.10.2005 1.d4 Nf6 2.c4 g6 3.f3 Svidler is a Gruenfeld player. He can still go into that with d5 but what has Morozevich got prepared. Svidler thought for a very long time in deciding the setup he wanted. 3...Bg7 4.e4 0-0 5.Nc3 d6 6.Be3 a6 7.Nge2 c6 8.Qd2 b5 9.h4 White has a huge choice here.

Black is a pawn down but its clear that white's King is vulnerable. 41...Rd8 42.Qe2 Qf4 43.Ra7 Kh6 44.Rc7 Rd2 45.Qe1 [45.Qe4 Qxe4 46.fxe4 Rd4 47.b4 Rxe4 48.b5 and white's pawn looks fast.] 45...Rd3 46.Ka2 Qxf3 47.Qc1+ Kh5 48.a4? There are a lot of alternatives here but this works out badly. 48...Qd5+ 49.Rc4 e4!  Black is now winning and finishes things off very accurately. 50.b3 Rd2+ 51.Ka3 Qd6+ 52.Rc5+ f5 53.Qg1 Kxh4! 54.a5 Rc2 55.b4 Qd3+ and mate follows. 0-1 |
