| Oct-14-06 | | razarahman: Can anyone tell what if 41.Kf1 appearantly looks ok to me |
 |
| Oct-14-06 | | Suzuki50: <razarahman> 41. Kf1 Qh1+ 42. Ke2 Qg2+ 43. Ke1 (43. Ke3 Bh6+) Qg1+ 44. Ke2 Qf2# |
|

 | | RandomVisitor: 44.Rd8+, 44.Rxf2 or 44.Ne6 all appear to lead to a white advantage. Perhaps 35.gxf4 was better for White. |
|
| Oct-14-06 | | percyblakeney: Never considered Rad8, thought it would begin with Qh2+ and be followed by lots of complicated variations that I couldn't find the strength to try to analyse. |
|
| Oct-14-06 | | ice lemon tea: can anyone explain to me how 40..Rad8 is the winning move? |
|
| Oct-14-06 | | greensfield: Missed this one, I concentrated on 40...Qh2 getting nowhere really. I guess the key is to undermine white's defensive rook formation so 40...Rad8! is a killer blow. I think white's best reply is 41.Bc3 but then 41...b5 42.Qe2 Qh2 43.Kf3 Bxg4 44.Kxg4 h5 45.Kg5 Qxe2 46.Rxe2 Rxd1 |

Quite clear. What does Rybka say about 42... b4 ? |
|
| Oct-14-06 | | nateinstein: This might be the first Saturday puzzle I got and understood the whole plan. Once you find Rad8 it's pretty obvious there is no defense. |
|
| Oct-14-06 | | Capastanka: Nailed 'er... |
|
| Oct-14-06 | | greensfield: <Suzuki50:Quite clear.> What does Rybka say about 42... b4 ?You don't need Rybka to say anything about 42...b4. The move is ridiculous, leaving a Bishop en prix, and with the king blocked in, leaving yourself open for attack along the d file. |
|
| Oct-14-06 | | Suzuki50: <greensfield> Could you show some variant, say after 40...Rad8! 41...b5 42.Qe2 b4 ? |

| Oct-14-06 | | Suzuki50: <RandomVisitor> Tx a lot for the analysis. Still I couldn't understand 45 ...Qc6 in the first variant.
(Ny the way is there a good manual of how to use Rybka ? Tx in advance) |
|
| Oct-14-06 | | NBZ: I thought the solution was Be4+ followed by Qh2+ and a check on the f-file with Rf8. Didn't bother to check it out though, and it probably doesn't work anyway. |

 | | al wazir: <RandomVisitor>: I also don't understand white's 44. Rd7 in the game as played. White gets more than just an advantage after 44. Rd8+: 44...Rxd8 (44...Bf8 45. e6+ Rf6 46. Bxf6#) 45. Rxd8+ Rf8 (45...Bf8 46. e6+ Rf6 47. Bxf6#) 46. Rxf8+ Bxf8 47. e6+ Bg7 48. Qxg7#. If black plays 44...Rf8 then 45. Rxa1 Rxa1 46. Rd7 Rg8 47. Rxg7 Rxg7 48. Qc8+ Rg8 49. e6+ Qb2 50. Bxb2#. Black can get a few checks, but I think they only postpone the inevitable. I didn't see 40...Rad8; I wouldn't have thought of playing it unless I spent an hour on the problem. But I have the satisfaction of knowing that the move I chose is the one a GM made, even if it loses. |

| Oct-14-06 | | Sami Jr: This should be under Arnason's notable games. What a way to beat Korchnoi with black. Is there any reason why Arnason didn't play 46...Bxe5+ earler? (discovered check and then 47.Rxg4 to take the Q then). Perhaps he was gunning for a quicker mate. |

If Arnason plays as you suggest 46...Bxe5 then white plays 47.Ke3 and continues as you suggest 47...Rxg4 then Kortchnoi has a mate as follows 48.Rd8+ Rf8 49.Rxf8+ Rg8 50.Bxe5# |

Right, but how about 47..Bxa1 ? |
|
| Oct-15-06 | | Sami Jr: <greensfield> Thank you. I missed the bishop on a1 to complete the mate. <Suzuki50> If 46...Bxe5+ 47. Ke3 Bxa1 then 48. Bxe5+ Rg7 49. Qxg7#! Arnason played his game very well and was still able to delay the gratification of capturing Krochnoi's queen with a discovered check. |
|
| Oct-15-06 | | Suzuki50: <Sami Jr: If 46...Bxe5+ 47. Ke3 Bxa1 then 48. Bxe5+ Rg7 49. Qxg7#!>
U might confuse a bit. After 47... Bxa1 U don't have anymore Bishop ! |
|
| Oct-16-06 | | Sami Jr: <Suzuki50> Yes I see what you mean now. But still if 46...Bxe5+ 47. Ke3 Bxa1 (this is the move you suggest) then 48. Rxh7+ Kxh7 49. Qh5#! Did I get your line correct now? |
|

 | | kevin86: I,too fell for the immediate Qh2+ Shame! |

| Oct-16-06 | | Suzuki50: <Sami Jr: <Suzuki50> Yes I see what you mean now. But still if 46...Bxe5+ 47. Ke3 Bxa1 (this is the move you suggest) then 48. Rxh7+ Kxh7 49. Qh5#! Did I get your line correct now?> Right, Tx ! |
