| Posted by aixrad goclub.org 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 goclub.org 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 goclub.org 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 goclub.org 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 goclub.org 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 goclub.org 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 goclub.org 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. |

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: Four share the spoils -- There was a four way tie for first at the 9th Karpov Poikovsky chess tournament in Siberia. Alexey Shirov could not hold onto his lead after an eighth round defeat at the hands of the 21 year old Azerbaijani GM Vugar Gashimov who was a surprise winner of the inaugural FIDE Grand Prix chess tournament at Baku earlier this year. Gashimov joined Shirov on the winning score of 5.5/9 and the leading quartet was completed by 2005 Russian chess champion Sergei Rublevsky and 2006 co winner Dmitry Jakovenko. A Volokitin – A Shirov; 9th Karpov Poikovsky chess ... Teenager causes angst -- The top seeds Evgeny Alexseev and Magnus Carlsen met in the second round at Biel with Carlsen black. The teenage chess prodigy managed to stir up huge complications from a quiet position when he broke out of his cramped formation but his opponent, a former Russian chess champion managed to defend himself and reach a drawn endgame despite the invasion of a black knight into the heart of his position. E Alekseev – M Carlsen; 41st Biel Festival (2); Queen’s Indian. 1.d4 Nf6 2.c4 e6 3.Nf3 b6 4.g3 Ba6 5.Qa4 Bb7 6.Bg2 c5 7.dxc5 bxc5 8.0–0 Be7 9.Nc3 0–0 10.Rd1 Qb6 11.Bf4 Rd8 (11...Qxb2 12.Rab1 Qxc3 13.Rxb7 Nc6 14.Bd2 traps the queen) ... Carlsen is in luck -- A little good fortune for Magnus Carlsen gave him victory over French chess number 1 Etienne Bacrot in the 3rd round at Biel and the lead on 2.5/3. Bacrot’s solid defence to the Queen’s Gambit was working out very well but when Carlsen complicated matters with a dubious pawn sacrifice his opponent collapsed and was lost just a few moves later. M Carlsen – E Bacrot; 41st Biel Festival (3); Queen’s Gambit. 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 e6 5.Bg5 Nbd7 6.cxd5 exd5 7.e3 Be7 8.Qc2 Nh5 (This simplifying and solid line was favoured by Ulf Andersson, it is notoriously hard to beat) ... | |
