| Posted by aixrad ajaxwrite.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 |

| Posted by lighttotheright ajaxwrite.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. |

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 ajaxwrite.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 ajaxwrite.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 ajaxwrite.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 ajaxwrite.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 ajaxwrite.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 ajaxwrite.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. |

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! |
Chess news: Chess Cheats, Spies, Crooks and Commies -- Nikolai Krylenko, the Soviet Commissar of Justice and Prosecutor General, used to sentence innocent people to death in show trials in the 1930s, until he himself perished in 1938 in Stalin's Great Purge. He neglected his work by spending too much time on chess and mountain climbing, his accusers claimed. In chess, Krylenko had a vision: He wanted to export the game as part of Soviet culture and to establish Soviet domination in the chess world. He began a ruthless game, playing with human pawns -- the Soviet chess masters and champions. In 1948, Mikhail Botvinnik won the world title. The aim was achieved. Since 1931, Botvinnik was regarded as the best Soviet chess player and ... Six tie for first in U.S. Open -- The 110th U.S. Open ended in a six-way tie for first place last Sunday in Indianapolis. Chess Grandmasters Dmitry Gurevich (Illinois), Jesse Kraai (El Cerrito, Calif.), Sergey Kudrin (Connecticut) and Alex Yermolinsky (South Dakota) and International Masters Alex Lenderman (New York) and Jacek Stopa (Poland) each scored 7 1/2 -1 1/2 in the 455-player chess event. The first five earned invitations to the 2010 U.S. Chess Championship in St. Louis. Gurevich defeated Kudrin in a speed-chess playoff for the title of 2009 U.S. Open champion. Eugene Yanayt of Santa Monica was the best-scoring Southern Californian, finishing in a tie for 18th place ... Bennett and King on chess: the Scandanavian, part 4 -- Hjartason-Hansen, Reykjavik 1995. Black to play. RB I'm looking for possible threats against my queen, always something to watch out for in the Scandinavian, and I don't like that its retreat squares on the short a5-d8 diagonal are blocked by the knight on b6. That said, I can't actually see a concrete threat. For example, if I play safe with 1... 0-0, what has White got? 2 a3 Bxc3 3 Bxc3 Qb5 and the queens come off. But so what? I might not be winning but I don't think I'm losing. 1... Nbd5, facilitating the queen's retreat and blockading the d4-pawn, looks okay: after 2 Nxd5 Nxd5, White's light-squared bishop is blocked in (or has to take). I can't ... | |
