| Jul-02-11 | | Patriot: I gave myself 10 minutes to solve this and spent all of it looking at the crazy 19.Nxc6 until I noticed it gets refuted: 19...Bxc6 20.Bxd5 Qxd5 (not 20...Bxd5 21.Re8+, etc.). Then about 2 or 3 minutes past the time control, I decided on 19.Bxc7. This is not a good way to analyze! |
|
| Jul-02-11 | | CHESSTTCAMPS: Material is even, but white is fully mobilized and black is not. The observation that two black rooks sit on their initial squares is suffcient to summarize the white advantage in this position. Black threatens 19... dxc4, but it's two late - the doubled rooks are ready to charge into the black position. Here, the natural continuation wins: 19.Bxc7 Qxc7 20.Re8+! (an exchange sac is low risk with the Ra8 out of play) and now: A) 20... Bxe8 21.Rxe8+ Kh7 22.Rxh8+ Kxh8 23.Qf8+ Kh7 24.Bd3+ g6 25.Nf5 f6 (gf 26.Bf5#) 26.Qxh6+ Kg8 27.Qxg6+ Kf8 28.Qxf6+ Qf7 29.Qh8+ Qg8 30.Qh6+ Kf7 31.Qxc6 wins due to the double threat of 32.Qxa8 and Nh6+. A.1) 25... Qe5 26.Qxf7+ Kh8 27.Qf8+ Kh7 28.Qxh6+ Kg8 29.Qxg6+ Kf8 30.Qxc6 with 4 pawns for the exchange and ongoing attack against the unsheltered king. A.1.1) 29... Kh8 30.Nh6! Qe1+ 31.Bf1 Nd6 32.Qxd6 with an easy win. A.2) 28... Ke8 (Kg8 29.Nh6#) 29.Ng7+ Kd7 30.Bf5#
A.3) 30... Ke8 31.Qxc6+ wins
B) 20... Kh7 21.Rxh8+ Kh8 22.Qf8+ Kh7 23.Bd3+ f5 (g6 24.Qxf7+ Kh1 25.Bxg6 forces mate) 24.Nxf5 wins. Time for review - A.1 can probably be improved. |
|
| Jul-02-11 | | CHESSTTCAMPS: Made it harder than necessary. |
|
| Jul-02-11 | | hedgeh0g: Got the line up to 22.Bd3+, but missed 22...f5 as a resource, although I don't personally feel it's much of an improvement over 22...g6. Otherwise, it wasn't a particularly difficult combination to calculate. |
|
| Jul-02-11 | | wals: Rybka 4 x 64
27.Qf5+, +#16. and Black resigned.
The clanger for Black.
18...d5, +5.67. Best, Nb6, +1.14.
and
22...f5, +#18 sort of ruined Black's day, there was no respite. |
|
| Jul-02-11 | | fightclub: <abuzic> You are correct. Sorry for the typo. As pointed out by <Jimfromprovidence>, there's no mate threat for white after 25...Qe5.
So <Jimfromprovidence> and <Once>'s line looks like the correct continuation to me. |
|
| Jul-02-11 | | jcb: Maybe someone else has already addressed this, but what is white's response if black plays 15 ... c5 instead of 15... Bc7? I don't see how white answers the simultaneous attacks on his queen and the night. |
|
| Jul-02-11 | | WhiteRook48: I got the first four moves |
|
| Jul-02-11 | | howlwolf: Easy for a Saturday; got it almost immediately. (That doesn't happen a lot.)Looked more at g6 instead of f5 so I didn't consider Bxg6 but feel 100% confident I would have found it. |
|
| Jul-02-11 | | Patriot: <jcb> If 15...c5, 16.Bb5 looks like a good candidate. If 16...Bxb5 17.Nxb5 saves the knight and black must deal with 18.Nxd6 or 18.Bxd6. |
|
| Jul-03-11 | | Passionate PatZER: Life MASTER -- may I suggest humbly that "PERFECT practise makes Perfect." I have spent a lot of time practising BAD habits so it is important to practise Correctly with good habits. |
|
| Jul-03-11 | | Dr. J: <CHESSTTCAMPS: ... 19.Bxc7 Qxc7 20.Re8+! and now: A) 20... Bxe8 21.Rxe8+ Kh7 22.Rxh8+ Kxh8 23.Qf8+ Kh7 24.Bd3+ g6 25.Nf5 f6 26.Qxh6+ Kg8 27.Qxg6+ Kf8 28.Qxf6+ Qf7 29.Qh8+ Qg8 30.Qh6+ Kf7 31.Qxc6 wins due to the double threat of 32.Qxa8 and Nh6+.> Correct, but there is one more point in this line: 31...Ne7 (counterattack) 32 Qb7 with the additional threat of Nxe7, and Black must lose N, R, or Q. |

 | | The Long Diagonal: This was an interesting puzzle. I had a look at it for about five minutes and couldn't figure it out. But yesterday night I had difficulties to sleep since it's so hot here (might be surprising for some people that it actually gets warm up here in Finland occasionally, but it was nearly 30 C yesterday) and instead I began poundering the position. I felt like playing 20.Re8+ because I realized that removing the light-squared bishop would weaken black's defense dramatically, especially the important b1-h7 diagonal. However, for a long time I completely overlooked that the white queen can jump to f8 from a3, playing 23.Qf8+. After I had understood this, it didn't take very long to find 25.Nf5! Must admit that I never even considered 25. .. Qe5, I thought that 25. .. f6 is completely forced. So the variation I calculated in the end and considered it to be optimal play by both sides was 20... Bxe8, 21.Rxe8+ Kh7, 22.Rxh8+ Kxh8, 23.Qf8+ Kh7, 24.Bd3+ g6, 25.Nf5 f6, 26.Qxh6+ Kg8, 27.Qxg6+ Kf8 28.Qxf6+ Qf7. Here I was calculating the consequnces of Qe8+, Qh8+, Qh6+ but couldn't find anything decisive and started already feel sleepy. Finally I decided that Qxc6 must be good enough to win since white has 4 or 5 pawns for an exchange (I was not sure whether there was a white pawn in b2) and the black king is exposed to checks with no more black pawns on K-side, so propably white can just exchange the queens at some point and win the endgame easily by advancing with his K-side pawns. Must say that I was quite surprised and happy to be able to solve this puzzle blindfolded almost 100% correctly (missing a few sideline defenses like 25. .. Qe5) since most Saturdays are too difficult for me even with a board to stare at. I have only tried blindfold chess a few times and never in a serious game but it would be interesting to take part in some sort of an Amber tournament for amateurs and patzers... wonder if there are any. |

| | The Long Diagonal: And yes, I also never seriously thought of .. f5 as an alternative to .. g6. But I don't think that was a serious miss since it doesn't help black at all, I think .. g6 is a better try because black still has some (tiny) hope that white might miss the killer Nf5. |

 | | Korora: I saw as far as the exchange sac and the ♗ check. |
|
| May-02-25 | | King.Arthur.Brazil: The king suspects that already saw this game before, didn't know when. Weak players didn't wait to play checks: 20. Re8+ Bxe8 21. Rxe8+ Kh7 22. Bd3+ g6 23. Rxh8+ Kxh8 24. Qf8+ Kh7 25. Nf5 (gxf5 26. Bxf5#) Qe5 26. Qxf7+ Kh8 27. Qf8+ Kh7 28. Qxh6+ Kg8 29. Qxg6+ Kf8 30. Nh6 Ke7 31. Qf7+ Kd6 32. Nf5+ Kc5 33. Qb7 (Rb8 34. b4# ) a5 34. b4+ axb4 35. cxb4# or d4 34. Qb4+ Kd5 35. Qc4#. But this line is so long, that has to be something better. |
