| Posted by drgandalf uskidscompute.com 5/21/2003 09:39:37 play online chess |  Subject: UnderpromotionMessage: Has anyone ever seen a game or a study involving the promotion of a pawn to a bishop? |
| Posted by indiana-jay uskidscompute.com 5/21/2003 10:11:08 play online chess | Message: Hmmm... I don't know but a Queen has the characteristic of a Bishop, so I don't think that it is necessary to promote to a Bishop. |
| Posted by tulkos uskidscompute.com 5/21/2003 11:32:19 play online chess | but it, would be easier, Message: say if you promoted to a queen or rook,the result would be stalemate, so you promote instead to a bishop which is easier to mate with than N + B. |
| Posted by wirzan uskidscompute.com 5/22/2003 00:53:16 play online chess | I've seen a game Message: where white promotes to a bishop to confuse his opponent. If he had promoted to a queen, black surely would have taken it, but he didn't take maybe cuz he would have lost an exchange (rook vs bishop) even tho it would have led to a draw game) White won the game. I don't remember where I saw the game, but I'll try to find it. |

| Posted by bigh uskidscompute.com 5/22/2003 10:36:29 play online chess | are there Message: any examples of under promotion to a knight? |
| Posted by gambitnut uskidscompute.com 5/22/2003 10:40:01 play online chess | I'm sure a knight is much more common Message: A knight can do things a queen can't. |

| Posted by caldazar uskidscompute.com 5/22/2003 12:06:17 play online chess | Message: "White: King on a5, bishop on c2, knight on d2, pawns on a6, d3, f5, g6, h4, and h5. Black: King on a8, bishop on f2, pawns on a2, a7, b2, d4, and h6. (FEN: k7/p7/P5Pp/K4P1P/3p3P/3P4/ppBN1b2/8 w - - 0 1) White to play and win." 1. g7 is incorrect because Black can stop White from promoting with 1...a1=Q+ and 2...Qg1 as posted. Therefore, to prevent Black from playing his queen to g1, White should play 1. Bb1. I'm not sure if this study is in the puzzles section or not; I don't visit that area regularly. |
| Posted by zdrak uskidscompute.com 5/22/2003 12:32:25 play online chess | Message: A nice one! Here's the solution, don't scroll down if you still want to solve for yourselves: 1.Bb1 (thanks for the hint!) a1=Q+ 2.Kb5 and now white is safe from checks, and threatens g7-g8. So black plays: 2...Bg3! 3.g7 Bb8 With the point that g8=Q (or R) is now stalemate after Qa5+ Kxa5. But white has: 4.g8=B!! threatening Bd5#, and of course the Queen sac is not a stalemate now. Which leaves black only: 4...Be5 Or any other other bishop move for that matter... 5.Bga2! The queen is trapped and white wins. |

Chess news: Players Remain Deadlocked at Moscow Tournament -- Day 2 of the Tal Memorial chess tournament in Moscow brought another round of draws as once again none of the competitors was able to score a win. As on Day 1, five draws did not mean that the games were boring. The competitors, who include 10 of the top 13 chess players in the world, played ambitiously, for the most part, but there were no major mistakes. Several of the games were quite interesting. Vladimir Kramnik of Russia, the former world chess champion, faced Viswanathan Anand of India, the current champion, in a reprise of their 2008 title match. Anand, who had Black for the second consecutive game, played the Grünfeld Defense and ... Paced by a 19-Year-Old Chess Star, France Revives Its Reputation -- In the 18th and 19th centuries, France was a center, if not the epicenter, of chess. Two of the greatest chess players of the era, Francois-Andre Danican Philidor and Louis-Charles Mahé de La Bourdonnais, were French, and the Café de la Régence in Paris was a gathering place for anyone who liked to play the game, including Benjamin Franklin and Napoleon Bonaparte. But as the game grew in popularity worldwide, France’s place in the chess hierarchy fell. Though the Russian-born Alexander Alekhine, who was the world chess champion from 1927 to 1946, became a French citizen in the 1920s and played for France in the first Chess Olympiads, he did not inspire ... Armenia and Azerbaijan vie for chess supremacy at Russia's expense -- More than 150 nations are affiliated to the global chess body Fide, yet team supremacy on the chess board is currently being fought out by two small Caucasian republics. In the process the pair have humilated their big neighbour Russia, for long the undisputed No1. When Armenia won the 2006 Chess Olympiad, the success was reckoned a surprise one-off. Then its squad retained the crown in 2008, sparking street celebrations in Erevan and the presidential plane home for the winning team. On both occasions the top-seeded Russians failed, as they had behind Ukraine in 2004. These results infuriated politicians and chess grandmasters in Azerbaijan, which has ... | |
