| Posted by aixrad blitzbrain.net 9/05/2008 05:18:31 Play online chess |  Subject: Checkmate or notMessage: I recently played with black this game  game with pianofred.
In this Position I generated the conditional move 20 Rf2 Re1+ ... with threefold repetition to save the draw because I had less material. pianofred mean I maybe could checkmate him forces but we both don't know how. Is this a forced checkmate position? Was it right to save the draw with threefold repetition? Greetings Ralf | ||||||||||||||||||||||||

| Posted by aixrad blitzbrain.net 9/05/2008 06:36:33 Play online chess | Message: Then I wa very stupd and blind at that moment ——— Anand Is World Chess Champion Again — Viswanathan Anand, the world chess champion, took advantage of a major error by Veselin Topalov to win the 12th and final game of their title match on Tuesday in Sofia, Bulgaria. The match had been tied at 5.5 points apiece. In addition to the title, Anand receives 1.2 million euros (about $1.5 million at current exchange rates). Topalov’s share of the prize fund is 800,000 euros, or about $1 million. Anand, an Indian grandmaster, became world chess champion by winning a tournament in Mexico City in 2007. He last defended the title in a match against Vladimir Kramnik, a Russian, in October 2008. Topalov, a Bulgarian, is a former world chess champion. He lost a bitter title match to ... Posted by chessnovice | blitzbrain.net 9/05/2008 21:39:08 Play online chess put a positive spin on itMessage: ——— Title Match Is Tied With One Game to Go in Regulation — There is one more regulation game left in the World Chess Championship match in Sofia, Bulgaria. If neither Viswanathan Anand of India, the titleholder, or Veselin Topalov of Bulgaria, win on Tuesday, they will have to go to overtime. On Sunday, they drew Game 11. It was the seventh draw in the match, though, like some of the other draws, it was not without drama. Anand had White and opened with the English — the first time in the chess match he had done that. No doubt he switched openings to try to catch Topalov off-guard, but it did not work. The players followed well-known theory for 10 moves, and then Topalov deviated from earlier games, though it was a minor ...

But Anand could have made a mark in this game. Anand and Topalov go into the 12th game of their chess match today with scores level. If drawn, tie-break rapid games will be played on Thursday. Topalov's declaration before the match that he would neither offer nor accept a draw has clearly had a liberating effect on both players, resulting in one of the most entertaining world chess championship finals we have seen in years. All the games have been long and hard-fought, so it's hardly surprising that tiredness is affecting play. Anand missed several chances to win in game 9, Topalov had a promising endgame in game 10 but ... Posted by wuzzie | blitzbrain.net 9/11/2008 04:13:47 Play online chess not checkmateMessage: ——— Playing for the World Title, Minus Any Fireworks — Before a world chess championship match, players spend months looking at their opponent’s games and studying opening systems, often with the aid of chess computers and databases. They also hire trainers, who are called seconds, to help. It is a time- and labor-intensive process. That is one of the reasons that fans look forward to the chess matches. They want to see what the players will do and what new ideas they have discovered, particularly in the openings. The current world chess championship match between Viswanathan Anand of India, the titleholder, and Veselin Topalov of Bulgaria has been as closely contested as predicted. But there have been no eye-opening innovations. Game ... Posted by lighttotheright | blitzbrain.net 9/11/2008 11:59:11 Play online chess Message: Aixrad, you did well to accept a draw in this position. After wuzzie's 20. Qg4+ Qxg4 21. fxg4...Rxb2 22. Nd2 would have left White with a possible decisive advantage. Although Black would have 2 passed pawns, the vertical isolation would have been difficult to defend. White would have opportunities to open his own passed pawns along the King-side once the black h pawn fell. And don't forget that White would still have an extra piece to fight in this position. Black cannot defend everything under best play. ——— With Another Draw, Chess Championship Match Remains Tied — Game 10 of the world chess championship match between Viswanathan Anand of India, the titleholder, and Veselin Topalov of Bulgaria, ended in a relatively uneventful draw on Friday. With only two games remaining in the best-of-12 series, the players are tied with 5 points apiece. If the match should remain tied after the last two games — which is a real possibility at the moment — it would go to a tie-breaker of four rapid games (each player starts with 25 minutes and has 10 seconds added to his time after each move). Such a tie-breaker was used in the 2006 world chess championship match between Topalov and Vladimir Kramnik of Russia. After each player won a game, and one ended ...

Qxf1#/Rxf1#, taking the win because of checkmate. You cannot say that Black did well to take the draw in this position !?!?!??? Posted by lighttotheright | blitzbrain.net 9/11/2008 12:18:58 Play online chess Message: It depends upon what position you are talking about. That is the danger of talking about this game or any like it. If you analyse a different position, you can get entirely different conclusions. Posted by tugger | blitzbrain.net 9/11/2008 15:27:10 Play online chess Message: For reference, White should have played 20. Qg4+ and he probably wins, forcing the Queens off the board with a pawn advantage (just the one pawn, as b2 is vulnerable to capture from the Rook). Better still would be to develop the Knight as opposed greedily snatching the pawn on move 19. Posted by tugger | blitzbrain.net 9/11/2008 15:33:07 Play online chess Message: The position in the first post is not a win for Black, as it is White to move, and he can save with Qg4+. It is only after White plays Rf2 that it becomes a win for Black. But I would still say that a draw for Black after missing a mate in one can not be considered a good result. Posted by lighttotheright | blitzbrain.net 9/11/2008 22:11:00 Play online chess Message: Then White made a mistake and Black did not take advantage of it. That's compounding mistakes. Both sides clearly intended the draw by repeating the position shown by aixrad on move 20. It did not matter that the repeating sequence was flawed. Neither player could see that flaw. Aixrad asked about the exact position he displayed in the first post. I merely confirmed wuzzie's analysis of that exact position. This game was a draw by repetition not by an accepted draw on move 20. It lasted longer than that (I knew that all along). The presumptive acceptance of a draw on move 20 was what I commented on...not the mistakes made later. The line of play I gave as example proves what I was talking about. To later criticize me for stating something I didn't is ludicrous. No where did I refute any of the previous analysis given by others that show the forced mates. But those forced mates do not materialize until after White's Rf2. Posted by tugger | blitzbrain.net 9/12/2008 08:20:12 Play online chess Message: "Aixrad, you did well to accept a draw in this position." is what i consider ludicrous. it's my opinion that aixrad should be disappointed, not pleased. i don't mean to pan him down, it's intended as constructive critisism. one should never be pleased about missing an easy win. aixrad should be looking to improve his game to the point where he can spot mate in one positions, and that means he should be disappointed when he misses them. this will hopefully drive him forward, trying to ensure he does not feel this disappointment again. i do know what lighttotheright is saying, though. in the position at the very top of this thread, aixrad is worse off positionally and materially. so i understand why he is saying a draw was not bad. perhaps a better way of approaching this problem is to directly answer the questions aixrad asks... "Is this a forced checkmate position?" - Not in this position. "Was it right to save the draw with threefold repetition?" - No, you should've waited to see what White's reply to Re2 was, then analysed the position, instead of putting up conditional moves. Perhaps then you might have found the win. Posted by lighttotheright | blitzbrain.net 9/12/2008 11:15:05 Play online chess Message: But I would like to point out that aizrad is only a 1300 level player. We shouldn't expect a 1600 to 1700 level or greater performance out of him. Is a draw the best result? Of course not. But don't forget that a draw is still a good result regardless. Certainly, it is a lot better than a loss. Posted by tugger | blitzbrain.net 9/13/2008 07:41:06 Play online chess Message: "But I would like to point out that aizrad is only a 1300 level player. We shouldn't expect a 1600 to 1700 level or greater performance out of him. " before i go on, i stress again it's just my opinion, but i really don't think that spotting that mate is 1600+ standard, in fact i would expect a 1300 player to have no trouble winning after Rf2. this is precisely the reason aixrad should be disappointed. if he's not disappointed, then how can he drive himself on to improve? if instead he shrugs his shoulders and says "well, a draw is a good result here", then i don't see him breaking into the 1600+ class. but maybe that's just the way i approach things. i guess he may see things differently. he may be boosted by the fact he didn't lose, and as such have more confidence. but i know i would be disappointed if i missed that. it's ironic really, as during the threefold repetition, both players took it in turns to blunder away a win! |
