The Jack Rabbit Chess Report (August 30): Chuckie wins the Tal; 11 Players Boycott Women's Chmpship
Edited on Sun Aug-31-08 12:41 AM by Jack Rabbit
Chuckie Defeats and Overtakes Moro to Win the Tal



Ukrainian grandmaster Vassily Ivanchuk defeated reigning Russian national champion Alexander Morozevich in the seventh round of the Mikhail Tal Memorial Tournament to come from behind to win the nine round event that finshed Wednesday.

Ivanchuk was also victorious over Hungarian GM Peter Leko in round six to begin his move. After six round, Morozevich was in the lead with 4½ points, while Ivanchuk had 2 victories and 4 draws for 4 points. Thus, Ivanchuk's win in round seven put him in the lead, a half point ahead of Morozevich.

Chuckie, as he is known to his fans, drew his remaining two games to end the event with 6 points out of nine games: 3 wins, 6 draws and no defeats. Meanwhile, Morozevich dropped his eighth round game to American grandmaster Gata Kamsky to fall further back. Moro took a short draw in the final round and settled for a disappointing second place tie among four players.

The other second place finishers were Israeli grandmaster Boris Gelfand, who won only one game but suffered no losses, former world champion Vladimir Kramnik of Russia and Ukrainian GM Ruslan Ponomariov.

For the 39-year-old Ivanchuk, the Tal championship is the latest in a year-long run high finishes in elite tournaments which has seen him playing the best chess of his life.



Women's Knock Out Championship Begins in Russian Caucasus; 11 Players Boycott



The Knock Out Tournament to name the Women's World Chess Champion began Friday in Nalchik in the north Caucasus Kabardino-Balkaria region of Russia without the eleven women who were invited to attend.

The boycott of the event is in reaction to recent Russian invasion of the Republic of Georgia. The six Georgian women who were invited sent a letter to FIDE president Kirsan Ilyumzhinov asking that the event be postponed and relocated for safety. Ilyumzhinov responded by pleading with the women to play in Nalchik, saying that it would be wrong to mix politics and sport.

The six Georgians include former women's world champion Maia Chiburdanidze, who became world champion in 1980 at the age of 17 by defeating Nona Gaprindishvili in a match. The others are Lela Javakhishvili, Sopio Gvetadze, Maia Lomineishvili, Sopiko Khukhashvili and Nino Khurtsidze.

Kirsan (everybody calls the FIDE president by his first name), in addition to being the president of FIDE, is also the president of the Autonomous Russian Republic of Kalmykia, a post to which he was appointed by then-Russian president Vladimir Putin.

The other players who are not participating in the event are Tea Bosboom-Lanchava of Holland, who is a native of Georgia; Irina Krush of the United States, who is a native of Ukraine; grandmaster Marie Sebag of France; Karen Zapata of Peru; and Ekaterina Korbut of Russia.



Youth Crush Seniors in Amsterdam

A five-member team of Rising Stars defeated a five-member team of experienced grandmasters ranging in ages from 41 to 77 in the annual Youth-Experience Team Match in Amsterdam.

The event finished yesterday with the Youth Squad taking 33½ out of a possible 50.

China's Wang Yue was the leading scorer for the Rising Stars with 8½ points out of ten. For this, Wang wins an invitation to next spring's Melody Amber Rapid/Blinfold Tournament in Nice.

18.Rxb6

  • When in doubt, take the pawn. (Steinitz)

18...Bf8

  • A better follow up to the sacrifice is 18...Nc4 19.Bxc4 Rxc4 20.f3 Qc7 21.Ne2 Rd8 when Black puts pressure on the c-pawn.

19.Ra6!

  • Being two pawns to the good, forcing exchanges is a good policy.

19...Qb7 20.Rxa8 Qxa8 21.Nb3 Nxb3

  • The failure of the pawn sacrifice is indicated by the fact that White must exchange Knights in order to recover the pawn, and he'll still have another pawn to make up.
  • No better than the text is 21...Nc4 22.Bxc4 Rxc4 23.f3 when:
    • After 23...Qc8 24.Rc1 Ba3 25.Rc2 Bb4 26.Qd5 Rxc3 27.Rxc3 Bxc3 White remanis a pawns to the good.
    • After 23...Qb8 24.Rc1 Bxb3 25.axb3 Qxb3 26.Qd3 White still has an extra pawn.

22.axb3 Bxb3

  • Black has regained the pawn sacrificed on move 17, but his poisition is no better now than before. White's outside passed pawn is a distinct advantage.

23.Rb1!

  • White still has the initiative.

23...Qa3 24.h3 Be6 25.Rc1 Rd8

  • A sharper defense is 25...Qa4 26.Qe1 Qd7 27.Qf1 Ba3 28.Ba6 Rc7, but White's c-pawn still plays the tune.

26.Qc2 Bb3 27.Qb1 Ba2 28.Qb5 Rc8?

  • 28...Bd6!? 29.Be2 Rc8 30.Rd1 Be6 31.c4 the advancing distant passer is an advantage for White.
  • After 28...Be6 29.Be2 Bg7 30.c4 Qa8 31.Qb1 Rb8 32.Qc2 White still has the outside passed pawn.

29.Qxe5!

  • The loss of this pawn is permanent.

29...Bc5

  • Exchanging pieces whn down in material is not a good idea.
  • Better is 29...Bg7 30.Qg3 Be6 31.Be2 Bxc3 32.Bf4 Qa5 33.Rb1, which takes care of the distant passer, but White still has the extra pawn.

30.Bxc5!

    • After 34...Ra5 35.Rd1 Qb3 36.Qd4 White remains up by two pawns.

33.Qe3 f6 34.Bf1

  • With a two pawn advantage, White wins faster by exchanging Rooks.
  • 34.Qxc5 Qxc1+ 35.Kh2 Qd2 36.Qd4 magnifies the advantage.

34...Qxc1

  • By contrast, Black should avoid exchanges, but now it make little difference.
  • 34...Re5 35.Rd1 Qb7 36.Bd3 Bf7 37.Qd4 Ra5 38.Rb1 gives White the initiative.

35.Qxc5 Qe1 36.Qd4

39.f3 h5 40.Kf2 h4 41.Qe3 Qc2+ 42.Kg1 Bc4

  • Black again offers to exchange, although already in the hole materially.
  • No better is 42...Kf7 43.Be2 Ke7 44.e5 Qa4 45.exf6+ Kxf6.

43.Bxc4 Qxc4 44.Kh2 Kf7

  • After 44...Kg6 45.Qa3 f5 46.Qe3 f4 47.Qa3 Qb5 48.Qa7 Black has no good moves.

8. Update (Monday): Few upsets in Nalchik's First Round
Edited on Mon Sep-01-08 11:48 AM by Jack Rabbit
The first round has been completed in the FIDE Women's Knock Out Championship in Nalchik, Russia with few surprises.

The biggest upset of round one was the victory of Armenian-American Kat Rohonyan over Ukrainian IM Natalia Zhukova. Ms. Rohonyan won the first Firday game and Zhukova the second Saturday. This lead to the playoff round yesterday, which Ms. Rohonyan won in the rapid phase by drawing the first game (in which she played Black) and winning the second.

Some suspense was involved as the when the tie-break between Poland's Monika Socko and Sabina-Francesca Foisor of Romania came down to the Armageddon game with Foisor playing Black, giving her the odds of draw. As she ran out of time with only one Knight each and Kings left on the board, Foisor claimed a draw by insufficient force. However, had Foisor misplayed the position, a checkmate was possible. Mrs. Socko appealed the ruling by the arbiter. The appeals committee ruled in Mrs. Socko's favor.

Due to the anti-Russian boycott of the event by some players, two matches ended in double default. These were the matches between Maya Lomineishvili and Sopiko Khukhashvili, both of Georgia, and between Sopio Gvetadze of Georgia and Ekaterina Korbut of Russia. As a result, Koneru Humpy of India and Russia's Alexandra Kosteniuk, both among the favorites to place high in the tournament, advance to the third round by default. In round 4, Koneru will play the winner of the match between Mrs. Socko and Hoang Thanh of Hungary by way of Vietnam while Kosteniuk awaits the winner of the match between her compatriot Tatiana Kosintseva and the reigning US women's champion, Anna Zantonskih.

9. Update (Tuesday): Matveeva eliminates reigning champ in Nalchik; Bilbao trmt begins
Nalchik: Reigning Women's Champion Xu eliminated in Second Round



Xu Yuhua of China, the reigning women's chess champion, was eliminated from the defense of her title in the second round of the FIDE Women's Championship Knock Out by Russian international master Svetlana Matveeva today.

Matveeva was a semi-finalist two years ago at the knock out tournament in Ekaterinburg when she was eliminated by Xu. Xu went on to defeat Alisa Galliamova in the final match to claim the title.

Matveeva will play Anna Ushenina of Ukraine in the third round beginning Thursday. Tomorrow will be played the second-round tiebreaks in order to resolve matches that ended 1-1 during the last two days.

Also advancing to the third round are: 14-year-old Chinese WGM Hou Yifan; Pia Cramling (Sweden); Lilit Mkrtchian (Armenia); Shen Yang (China), who scored a major upset over her compatriot, Zhao Xue; Tatiana Kosintseva (Russia); Ruan Lufei (China); and Hoang Thanh Trang (Hungary). Koneru Humpy of India and Russia's Alexandra Kosteniuk advanced without second-round opposition due to the boycott of 11 players to protest the Russian invasion of Georgia.

The most important of tomorrow's tiebreaks will feature former champion Antoaneta Stefanova of Bulgaria against Ju Wenjun of China. Other tiebreaks pit Viktorija Cmilyte (Lithuania) against Nadezhda Kosintseva (Russia); reigning girls' champion Drovavalli Harika (India) against Anna Muzychuk (Slovenia); Nguyen Thi Thanh An (Vietnam) against Elena Sedina (Italy); Inna Gaponenko (Ukraine) against the only surviving American player, Kat Rohonyan of Baltimore.


Bilbao Masters begins today



The Bilbao Masters' Tournament, the final leg of the FIDE Grand Slam for 2008, began today in Spain.

The other legs of the 2008 grand slam were the Corus A Tournament in Wijk ann Zee, played in January; the Morelia-Linares Tournament in Mexico and Spain in February and March; and the MTel Masters' Tournament in Sofia in May.

The participants in Bilbao are: reigning world champion Vishy Anand (India); 17-year-old Magnus Carlsen (Norway); Vassily Ivanchuk (Ukraine); former FIDE world champion Veselin Topalov (Bulgaria); Teimour Radjabov (Azerbaijan); and Levon Aronian (Armenia).

The only decisive game in the first round saw Magnus Carlsen, playing Black, defeat Levon Aronian in 51 moves.

10. I like the Bilbao scoring system.
3-1-0 - that's something I can wrap my head around as a soccer fan, and it rewards players that push for wins. That's important in a big GM tournament like this one.

11. I'd like to watch how that plays out
It might be better than an idea I've kicked around chess discussion boards of just making games won the first tiebreak universally. One still gets the same number of points for two draws on the hand and a win and a loss on the other, but the player with a win and a loss will finish ahead of the one with two draws on tiebreak.

For those who don't know what we're talking about, in Bilbao the winner of a game will be awarded 3 points and each player will be awarded a single point for a draw.
