| Posted by aixrad debiantoday.com 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 | ||||||||||||||||||||||||

These monthly tournaments offer a great introduction to the fun of tournament chess and help people learn some of the basic rules of tournament play. Most chess tournaments are rated, meaning they require a membership to the United States Chess Federation as a requisite for participation. Once a player joins the USCF and begins playing tournaments, he will receive a rating that indicates his strength based on the ratings of his opponents and his results. Our beginner tournaments, however, require no USCF membership and are designed to encourage chess players to ...

London was the world chess center in the mid-19th century when the first two important tournaments were organized: the knockout event in 1851 and the round-robin in 1862, both won by the German master Adolf Anderssen, one of the greatest chess attackers. Did the current tournament eclipse the events played roughly 150 years ago? Anderssen did not like the playing conditions in 1851. The chairs and tables were too low for him, the chessboard too big and the players were confined to a small place. But the German chess master would have ...

This is the final position of the chess game we considered last week. Kramnik has just played his rook to c8 and Howell promptly resigned. Why? RB: Yes, why did Black resign? With two queens on the board you'd think he'd be fine. But what are his options here? I can see two. The first doesn't seem to help Black: 1…Rxc8 2 Qxc8+ Kh7 3 a8=Q when, with the threat of mate on h8, Black has to continue 3…Qxa8 and after the recapture White is a knight and a pawn up. The alternative is 1…Qxb8 2 axb8=Q Rxc8 3 Qxc8+ Kh7 4 Qf5+, when White is again a knight and pawn to ...

Such an idea may seem absurd to some people, but the World Chess Federation has been lobbying the International Olympic Committee for years to include chess in the Games. As part of its efforts, the federation even instituted drug testing to bring chess into compliance with the committee’s rules. (Players have grumbled about this, pointing out that aside from caffeine, there are no drugs that can plausibly help them play better.) In making a case for chess, Kirsan Ilyumzhinov, the president of the federation, has said that curling is essentially “chess on ice.” The Olympic committee has granted the federation status as a Recognized International Sports Federation, but ... Posted by lighttotheright | debiantoday.com 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. ——— On Chess: Game is brainy mix of theory, practice — The frequent emphasis on rote learning is decried by critics of formal education. Learning is often reduced to reproducible sound bites amenable to multiple-choice testing. The result can be a learned incapacity in making complex decisions demanding fluid thinking and purposeful action. We often hear from those who use chess as an educational tool that “Chess makes kids smarter.” But why? Chess, like other games, is a testing ground that combines theory and action. It is no accident that the best performers in sports are often effective men and women who achieve new successes when their athletic careers are over. Playing chess involves a continuous mental process of applying and modifying concepts to ...

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 | debiantoday.com 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 | debiantoday.com 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 | debiantoday.com 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 | debiantoday.com 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 | debiantoday.com 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 | debiantoday.com 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 | debiantoday.com 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! |
