| Posted by aixrad blitzbrain.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 | ||||||||||||||||||||||||

It pits Judit Polgar of Hungary, the strongest woman chess payer in history, who is now ranked No. 46 in the world, but once was in the top 10, against Gregory Kaidanov, a Ukrainian-born American grandmaster, who is ranked No. 261. The match is four games and has an interesting twist: Each game begins with a different variation of the Sicilian Defense. The first game was on Monday and was won by Kaidanov, who had White, and featured the Sveshnikov. The second, which was won by Polgar, was on Tuesday and was a Dragon. The third chess game, which is being played on Wednesday, and can ...

Continuing our look at the chess equivalent of route one football – the f-pawn advance... RB Well, let's see what happens when we push – 1 f5. The answer comes back faster than Manchester United on the break, not much. Black is under no compulsion to take the pawn and can instead centralise with 1…Nd4 or even 1…Qd4, or start getting the queen's rook into play with 1…Rac8, and 1…Nb4, hitting the d-pawn, would be irritating. All right, let's try to be logical. What's wrong here is that even if we could swap off pawns on the f-file, the f1-rook would remain blocked by the bishop. Let's ...

The first was the Gibtelecom Chess Festival in Gibraltar, which ran from Jan. 26 through Feb. 4. Among the world-class chess players who competed were Etienne Bacrot of France, Sergei Movsesian of Slovakia, Francisco Vallejo Pons of Spain, Michael Adams of England, and Gata Kamsky of the United States. The chess tournament ended in a nine-way tie for first, with Adams winning a four-person playoff to take the title. The Moscow Open, which overlapped with Gibtelecom and ended on Feb. 7, was divided into four sections — A, B, C and D — with ...

Alexander Grischuk of Russia, the defending champion, is in second place after beating Vugar Gashimov of Azerbaijan in Round 8 on Sunday. Levon Aronian of Armenia is in third, having managed, like Topalov, not to have lost a game in the chess tournament. Unlike Topalov, who has won three games, Aronian has not won a game either. So far, 25 percent of the games have been decisive, but that does not mean that the other 75 percent have been dull. Quite the contrary. The games have mostly been hard fought and exciting, even ... Posted by lighttotheright | blitzbrain.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. ——— Weekend of Fun and Friends Between Battles on the Chess Board — The highlight of the year for many chess players is Washington’s Birthday weekend, when four amateur team championships are held across the country. There are no cash prizes, but the chess tournaments are popular because of the camaraderie. Players walk back and forth chatting before, after and even during the games. Some renew friendships with competitors they see only once a year. The World Amateur Team East tournament in Parsippany, N.J., the biggest and oldest of the chess events, celebrated its 40th birthday this year. There were 1,150 players and 271 teams, down from 283 teams last year, said Steve Doyle, the tournament’s director, who ...

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.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 | blitzbrain.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 | blitzbrain.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 | blitzbrain.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 | blitzbrain.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 | blitzbrain.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 | blitzbrain.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! |
