Leko 1 – 0 J. Polgar

On move 12, Judit made the first of many inaccuracies. A better option would have been 12…d5. Her biggest error was on move 18…Nh5? 18…Ba3 would have lead into an interesting game. This was certainly not a well played game by either side. However, Leko made fewer inaccuracies and that is why he collected the full point. I am not sure why my sister resigned on move 25. I agree that her final position was very bad but it was far from resignable. I would have certainly played on.

Kasimdzhanov 1 – 0 Anand

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 Ng4 7.Bg5 h6 8.Bh4 g5 9.Bg3 Bg7 10.h3 Ne5 11.Nf5 Bxf5 12.exf5 Nbc6 13.Nd5 e6 14.fxe6 fxe6 15.Ne3 0–0 16.Be2 Qe7 17.0–0 Rad8 18.Bh5 Kh8 19.Re1 d5 20.a4 Nc4 21.Nxc4 dxc4 22.Qg4 Qb4 23.Qxe6 Rd2 24.Rad1 Nd4 25.Qe4 Nf5 26.Be5 Rxf2 27.Bf3 Rd2 28.Bxg7+ Kxg7 29.Qe5+ Rf6 30.a5?!

This was not a good game for Anand. I think he underestimated Kasim. The final blow was 30…Nh4?? Perhaps he was trying to blitz Kasim who had very little time left at that point. Anand now trails Topalov by a full point. This is a great come back by Kasim after a horrible game against Judit yesterday. A well deserved win for the reigning FIDE World Champion.

Topalov 1 – 0 Adams

Again, what else can we say about Topalov? He is on a hot streak and he wins with just about any position. He now has the sole lead with 3.5/4. He was so close to a 4/4 start. The key question is can he continue to sustain this level of play? If he can, he will be unstoppable. I am not sure what was the purpose of Adams’ move 16…b5? That simply allowed Topalov to open up the position. The final blow in an already bad position was 35…Rc8?? It does not look like Adams is in good form at all. There are still 10 games left to play. He still has a chance to turn things around for a respectable finish.

Morozevich is not playing well at all. He actually lost a pawn up endgame. There were plenty of minor errors but the a few such as 45. Qe1?, 48. a4?, 49. Rc4?? really stood out. Svidler has been playing very steadily and he is now in clear second. This sets up a very interesting match up in round 5 when he will have white against Topalov.

The fighting spirit has been very high so far. Unfortunately, the level of play is not up to the World Championship level. There have been plenty of errors by a number of players. This will all come down to tough battle of nerves among the participants.

Standings after round 4

1. 3.5 GM Veselin Topalov (Bulgaria 2788)
2. 3.0 GM Peter Svidler (Russia 2738)
3. 2.5 GM Viswanathan Anand (India 2788)
4. 2.0 GM Rustam Kasimdzhanov (Uzbekistan 2670)

5-6. 1.5 GM Judit Polgar (Hungary 2735)
7-8. 1.0 GM Michael Adams (England 2719)
7-8. 1.0 GM Alexander Morozevich (Russia 2707)

Tomorrow (Sunday) will be a needed day-off for the players. Round 5 will resume on Monday.
