| Posted by binkers ability-tw.com 8/21/2002 12:50:34 |  Subject: should White win this endgame? Message: Hi all you expert analysts! here is an endgame with W having a 2P advantage, B's of opposite colours. I was black, and thought for sure I had lost, but the game ends in a draw, with Black apparently successfully blocking all White's possibilities of promoting a P. Could W have won? 1. e4 c5 2. Nf3 d6 3. c3 Nf6 4. Bc4 Nc6 5. d3 e6 6. O-O d5 7. exd5 exd5 8. Bb5 Bd6 9. Re1+ Be6 10. Ng5 Qd7 11. Nxe6 fxe6 12. Qe2 Kf7 13. Nd2 Rhe8 14. Nf3 Re7 15. Bg5 e5 16. Nh4 e4 17. Bxf6 Kxf6 18. dxe4 dxe4 19. Rad1 g6 20. Rd2 Rd8 21. g3 Qc7 22. Ba4 Na5 23. Qg4 Nc4 24. Rde2 Qc8 25. Qxc8 Rxc8 26. Bb3 Ne5 27. Re2xe4 c4 28. Rf4+ Kg7 29. Bc2 Bc5 30. Kf1 Rd8 31. Re2 b5 32. Rfe4 Kf6 33. Ng2 Rdd7 34. Nf4 Nf3 35.

| Posted by atrifix ability-tw.com 8/22/2002 14:56:54 | Not sure, Message: but I think that 48. Rd4?? was the decisive mistake. Winning chances are greatly reduced with the rooks off the board. If White wanted to win, he should have played something like 48. Rc5. After 54. f4 the game is quickly drawn. In order to preserve any winning chances White should have tried to activate his king, even at the cost of material. For example, 54. Bb7+ Kc4 (Ke6 is more tenacious, but White has better chances to win with Ke4 than in the game) 55. Ke4! Be1 56. f4! Bxg3 57. Bf7 g5 58. f5 with some chances to win because the King is better placed and White now has two passed pawns. | ||||||
| Posted by binkers ability-tw.com 8/22/2002 17:22:34 | simplifying in the endgame Message: thanks for your reply! yeah, I wondered about the R trade too, specially since it disconnected his P's. yet the general principle is to simplify when you're up material, and one would think a 2P advantage should be enough to win. I felt he was immobilized considerably by the fact the B's were of opposite colours, so they couldn't be traded off. anybody else like to comment?? ——— Chess Bundesliga Kicks Off — Five years ago, the current French women's chess champion, Almira Skripchenko, became a poster girl for the German Bundesliga, arguably the world's strongest national chess team competition. Kicking the chess pieces, she made a symbolic connection between soccer and chess. FIFA, the governing body of soccer, has 208 member countries, the most of any sport. The World Chess Federation (FIDE) with 159 nations is second. In many countries chess is considered sport, run by national sports organizations, and the International Olympic Committee (IOC) is seriously thinking to include it in the Summer Olympics. And unlike in many sports, women can compete against men across the chessboard ... Posted by atrifix | ability-tw.com 8/23/2002 15:12:31 Rules and General PrinciplesMessage: The golden rule of chess is that there are no rules. Blindly following general principles like "trade off pieces when you are up material" and etc. can often (as in this case) lead to failure, and one should check not the principle but the situation on the board. In this case, the R trade leaves ONLY the opposite colored bishops. Of course, a pure king ending would be an easy win for White, but pure opposite color bishop endings have much more drawish potential than, for example, opposite colored bishops + 2 rooks. Black can establish a blockade here and the position is drawn. Following the trade of rooks, white's only attempt to win would have been to prevent Black from establishing such a blockade, even if it meant giving up material. Anyhow, White should probably win after 48. Rc5, for example: 48... Ke6 49. Bb7 Ke7 50. Ke4 followed by f4, Bd5, Kd3-c4, and advance of the pawns. ——— Kramnik Wins Again, Carlsen Loses Again — Vladimir Kramnik is in excellent form, Magnus Carlsen is not. With a smooth, seemingly effortless performance on Sunday, Kramnik, a Russian, scored his second consecutive win to begin the Bilbao Final Masters. He beat Alexei Shirov of Spain after Shirov neglected his development to chase down and trade off one of Kramnik’s bishops. The consequence of his decision was that Kramnik was able to win an exchange and force an endgame where his material superiority was too much for Shirov. While Kramnik was winning his second game, Carlsen, the world’s top-ranked chess player, was losing his second (actually, it was third, including his last game at the Chess Olympiad in ... Posted by nottop | ability-tw.com 8/23/2002 15:25:07 bishops opposite colorsMessage: A fascinating message. Thank you. I agree with you that Rd4 is not the best. BOOC endgames are very difficult to win. The chances of a win increase with the presence of more pieces and more pawns. More pieces diminish the drawing tendencies of BOOC (both Dvoretsky and R. FIne have shown this in their works). Since Rd4 lead to both less pieces and less pawns it was not a promising idea. I would have liked Rc7 instead. It is hard for black to reasonably defend the h pawn and natural moves - like Bd2 (targeting the c3 pawn) don't seem to work because of Ke2 with the idea of moving Bd3 and trapping the black bishop - into a trade of bishops. With bishops off the board this ending must be won. I think you are fortunate that white was apparently not familiar with the nuances of BOOC - his moves before were imaginative and creative. ——— Kramnik Takes Early Lead in Bilbao Final Masters — The Bilbao Final Masters started Saturday and Vladimir Kramnik of Russia got off to a quick start by beating Magnus Carlsen of Norway in Round 1. The Final Masters was conceived as a championship for the winners of the elite chess tournaments of the year, including Linares and Corus (now sponsored by Tata Steel, which bought Corus) among others. The idea ran into trouble last year when the prize fund was cut because of the global financial downturn and Veselin Topalov of Bulgaria, the-ranked qualifier, declined to participate. The other problem the Final Masters has had is consistency. M-Tel was not played this year, and there have been additions to the list of eligible chess tournaments, including ...

Vern ——— Ukraine edges out Russia in World Chess Olympiad — Russia again failed to end its gold medal drought at the biennial Chess Olympiad this week despite home advantage. Ukraine, whose No1, Vasily Ivanchuk, also won the individual top-board gold, narrowly edged the hosts with Israel third. Russia's last success was in 2002, since when Ukraine and Armenia have each had two victories. England, seeded 12th, proved inconsistent and finished 24th despite Michael Adams's win over the world No1, Magnus Carlsen, and a fine unbeaten 6/8 by Gawain Jones, 22, on bottom board. Carlsen himself lost three games and now has only a small lead over India's world chess champion, Vishy Anand, in the global rankings. The most significant gain was by ... |
