Mamedyarov beats Topalov at Essent Tournament

Essent Chess Tournament 2006

The 10th edition of the Essent Chess Tournament is taking place from October 20 to 28, 2006. The location is the city of Hoogeveen. As in the past years there are a number of competitions: a Crown Group, a strong Essent Open, an Amateur Tournament, a pub tournament and an event for youth. Commentary on the Crown Group games will be available in the chess café in Hoogeveen. The games are also being broadcast live on the Internet, on the official site and on Playchess.com..

Participants of the Crown Group

The star attraction at the 2006 Essent tournament is former FIDE world champion Veselin Topalov, who still sports an Elo rating of more than 100 points above the average of his opponents (85 more than the second seed).

Shakhryar Mamedyarov is the Junior World Champion, Judit Polgar the strongest female player (by a good bit) in the history of the game, and Ivan Sokolov the strongest Dutch player at the current time. Judit is a well-known face in Hoogeveen, and this is her eighth appearance there.

• Full details on the other tournaments is available on our first Essent report.

Round one

Shakhryar Mamedyarov beat Veselin Topalov in a Semi-Slav Meran, in which twenty moves was theory and the outcome of the game (probably) hinged on an inaccuracy on move 35. Judit Polgar played an Open Ruy Lopez against Ivan Sokolov, who played vigorously with the black pieces. But his attacked collapsed near the end and Judit could chalk up a first-round win in this event.

10th Essent Hoogeveen NED (1), 22.10.2006
1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.e3 e6 5.Nf3 Nbd7 6.Bd3 dxc4 7.Bxc4 b5 8.Bd3 Bb7 9.e4 b4 10.Na4 c5 11.e5 Nd5 12.Nxc5 Nxc5 13.dxc5 Bxc5 14.0-0 h6 15.Nd2 0-0 16.Ne4 Bd4 17.Nd6 Bc6 18.Bh7+ Kxh7 19.Qxd4 f6 20.Bd2 Qd7N Veselin Topalov deviates, avoiding the usual 20...fxe5, which has produced a balanced score between white and black in the past. 21.Rac1 a5 22.Qd3+ f5 23.Rc5 Ne7 24.Rfc1 Ra7 25.Be3 Rfa8 26.Qe2 Ra6 27.h4 Qd8.

28.Bg5 hxg5 29.Qh5+ Kg8 30.Qf7+ Kh7 31.Qh5+ Kg8 32.Qf7+ Kh7. It looked like a quick draw, but after repeating twice Mamedyarov decides to try for a win. 33.hxg5 Ng6? Surely holding on to the bishop with 33...Be8 would have been better. 34.Rxc6 Qxg5. Now material is equal but White has a powerful attack. 35.Rc8.

Now a normal continuation would be 35...Rxc8 36.Rxc8 Rxd6 37.exd6 Qd2 (but not 37...Qg4, which loses) with a perpetual to follow. We don't know what Topalov had in mind when he played 35...Nf4? 36.g3 Rxc8 37.Rxc8. Now the path of the queen to d2 is blocked by the knight. 37...Qg4 38.Qg8+ Kg6 39.Qe8+ Kh7 40.Qh8+. Now any black dreams of a perpetual have dissipated. 40...Kg6 41.Rc7 Qd1+ 42.Kh2 Qh5+ 43.Qxh5+ Nxh5 44.Re7 Rc6 45.Rxe6+ Kh7 and the Junior World Champion finishes off the former FIDE World Champion with a florish: 46.Nf7 Rxe6 47.Ng5+ 1-0.

Peter Doggers, Editor-in-chief of the Doggersschaak web site, has made a very nice video with the key moments of the Mamedyarov-Topalov game – 36.g3, 41.Rc7, 44.Re7, the resignation – and put it on (where else?) YouTube.
