| Posted by aixrad legalserv.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 | ||||||||||||||||||||||||

Four of those teams — the top two Russian teams, Hungary and Armenia — were ranked among the top six at the start, so their standing is no surprise. But three of the leaders — the Netherlands, the Republic of Georgia and Vietnam — are unexpected, in particular the last two, who were ranked No. 20 and 27, respectively, when the chess competition began. Several of the pre-tournament favorites ran into unexpected trouble early on. Ukraine, which was ranked No. 2, gave up a drawn match to Croatia, No. 28, in Round 3. (Matches are between teams of four players). Ukraine is now tied for ...

The Yemeni Sports minister, Hamud Mohammed Ubad, took the unusual decision after chess players ignored instructions to pull out if drawn against Israel, which is widely criticised in the Middle East for its policies towards the Palestinians. "This was an individual action contrary to the policy of Yemen, which refuses any normalisation with Israel," said Mr Ubad, adding that the chess players were on their way home from Minsk. Like several other Middle Eastern countries, Yemen does not have diplomatic relations with Israel and bars ...

According to the Olympiad’s Web site, there are 1,300 players from 144 countries. The Chess Olympiad, which was first held in 1927 (or 1924, unofficially), is convened every two years. The 2010 Olympiad is particularly important as elections for the top offices in the World Chess Federation, the game’s governing body, will be held near the end of the competition. Prior to the start of the Olympiad, it had been plagued by problems, including a race to finish building the main venues before the teams arrived. Now that the chess event has ...

But there are more squares in chess, mostly invisible, as part of an amazing chess geometry hidden in chess players' minds. One classic square is often used in pawn endgames when a king is chasing the enemy's passed pawn. The king doesn't have to walk in horizontal or vertical lines, he can run diagonally or zig-zag across the field. But he needs to be close enough to catch the pawn. How close? The king has to walk into a square whose one side is defined as the distance between the pawn and its promoting square at the edge of the board. We can use a famous study by Richard Reti as an example. The world-class player ... Posted by lighttotheright | legalserv.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. ——— Lahno Wins Women’s World Blitz Chess Championship — To be good at blitz, or speed, chess, players must think quickly and have good tactical skills. That is why the best chess players under slow, or classical, chess time controls are not necessarily the best at the faster form of the game. Though only 20 years old, Kateryna Lahno of Ukraine has been among the best women players in the world for seven years and is now ranked No. 7. She is actually ranked higher than Alexandra Kosteniuk of Russia, the current women’s world chess champion, who is No. 10. She is clearly an excellent classical chess player and has won the European Individual Women’s Championship twice (in 2005 and 2008). Now she has proven that she may be even more adept at speed chess. ... Posted by heinzkat | legalserv.com 9/11/2008 12:04:46 Play online chess Message: Should Black play 23. ... Re2, taking the draw because of threefold repetition, or should Black play 23. ... 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 | legalserv.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 | legalserv.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 | legalserv.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 | legalserv.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 | legalserv.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 | legalserv.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 | legalserv.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! |
