| Jan-21-21 | | newzild: Tough - I missed 45. Qg7. |
|
| Jan-21-21 | | BxChess: I figured the first move of the puzzle had to be 42. Ne8+ but I couldn't see the finish because I also missed 45. Qg7 |
|
| Jan-21-21 | | Walter Glattke: 42.Nh5+ Kg8 43.Qf6 gxh5 44.gxh5 Kh7 45.h6 Rg8+ 46.Kh2 Qc7 / 42.Ne8+ Kh7 43.Qh5+ Kg8 44.Nf6+ Kg7 45.Qh7# / 42.Ne8+ Kg8 43.Qf6 Qxc5+ 44.QxQ or 43.-Rxe8 44.Qxf7+ Kh8 45.Qxe8+ mating / 42.Ne8+ Rxe8 43.Qf6+ Kh6 43.g5+ Kh5 44.e.g.Qxf7 wins |

 | | al wazir: My idea was 42. Nh5+, with a continuation like 42...Kh7 43. Qf6 gxh5 44. g5 Qd8 45. g6+ Kg8 46. gxf7+ Kh7 47. Qxd8 Rxd8 48. f8=Q. But after 42...Kg8 43. Qf6 gxh5 44. gxh5 Qd8 the attack peters out. |
|
| Jan-21-21 | | Granny O Doul: The quiz position seems legit, even if the play leading to it is implausible in places. The more obvious 44. Qf4+ also wins handily. |
|
| Jan-21-21 | | Walter Glattke: 45.Qxf7? Qxd4+ / 45.Qg7 Kxg5 46.Rxf7 d5 found no clear solution |
|
| Jan-21-21 | | VincitQuiSeVincit: 45.Qg7 Kxg5 46.Qf6+ followed by 47.Rf4 wins for white |
|
| Jan-21-21 | | Messiah: Nice puzzle, I liked it very much. |
|
| Jan-21-21 | | Brenin: After 42 Ne8+ Rxe8 43 Qf6+, the alternative 43 ... Kh7 44 Qxf7+ Kh6 45 Qxe8 Qxd4+ gives Black a chance of survival, though the prospects do not look good. |
|
| Jan-21-21 | | Refused: First try was 42.Nh5+ Kh7 43.Qf6 gxh5 and now there's the small problem, that the useless Bishop on c8 is covering f5 which kinda takes out the fun of ideas like rf5-h5.
Other follow ups involving g5 had a feeling of going nowhere. Second try. 42.Ne8+! this way at least the night is clogging the h-file.
a) 42...Kg8 43.Qf6 is already curtains, if the King moves to the h-file, white will simply insert qh4+ then get the same position on move later.
b) 42...Rxe8 43.Qf6+ Kh6 is the critical line. 44.Qf4+ Kg7 45.Qxf7+ Kh6 46.Qxe8 +- Black can try to pretend to have some swindle with 46...Qxd4+ but with the Queen on e8 covering the pawn on e4, I fail to see anything materializing for black. ah, I see. Shimanov went with 44.g5+ Kh5 45.Qg7 instead of my prosaic Qf4-Qxf7. I still claim to have solved it, as I don't see how the game continuation is superior to my solution. |
|
| Jan-21-21 | | VincitQuiSeVincit: In the alternative 43... Kh7 44.Qxf7+ Kh6 45.g5+ Kxg5 46.Qf6+ followed by 47.Rf4 wins for white (if 45.g5+ Kh5 then 46.Qh7+ followed by 47.h4+ wins for white) |
|
| Jan-21-21 | | Viennablue: ...28. Bb3?? looses the Rc7 without any compensation. Looks like a mistake in the transcript.... |
|
| Jan-21-21 | | Viennablue: Same after 31.Rc7?? |
|
| Jan-21-21 | | Brenin: <Viennablue>: There's clearly something wrong with the transcript: moves 28, 29, 31 and 32 make no sense, and should be deleted, unless the players had an agreement to make two nonsensical repetitions in order to get closer to the time control, something i've never heard of before. |
|
| Jan-21-21 | | Cellist: I saw all the game moves but then wanted to do 44. h4 without much thinking. That looses crushingly to 44. ... Qc7, and the opportunity for White to checkmate is gone. This shows how even after a successful and correct combination one needs to calculate carefully. |
|
| Jan-21-21 | | saturn2: I found 42. Ne8+ and that accepting the knight
loses the rook. However if 42.Kh7 black has to take anyway. 43. Qh4+ Kg8 44. Qf6 |
|
| Jan-21-21 | | saturn2: Seems I missed ...Kh6 but only looked at Kg8 snd Kh7. |

|
| Jan-21-21 | | beugi19: Yes, I think that without the Qf4+ resource this problem would be Saturday level. Qg7!! is crazy hard to spot. |
|
| Jan-21-21 | | King.Arthur.Brazil: After 42. ♘e8+ ♔g8 43. ♕f6 Black has no escape: a) 43...♖xe8 44. ♕xf7+ ♔h8 45. ♕xe8+ ♔h7 46. ♖f7+ ♔h6 47. ♕h8+ ♔g5 48. ♕f6+ ♔h6 49. ♕h4# or b)43...♕xd4+ 44. ♕xd4 f6 45. ♘xf6+ ♔g7 46. ♘h5+ ♔h6 47. ♖xf8 gxh5 48. ♕f6+ ♔h7 49. ♖h8# among other possibilities. c) Of course, any other move, 44.Qg7#. For 43... ♔h6 44. ♕f4+ ♔g7 45. ♕xf7+ ♔h6 46. g5+ ♔xg5 47. ♕f6+ ♔h5 48. Tf4, I lost one move. The game continued with 45...♔xg5 46. ♕f6+ ♔h5 or ♔h6} 47. Tf4} with the same check-mate near. However, in a game I'll surely play my line.
The position up to move 10 can be reached by some oppenings, including the called closed Sicilian defense, which the great ex-champion Smyslov used to play with White on his golden age (51-57), and I like it too, although without success in tournaments. .I really found no reason to play 31... ♕b5? Maybe, 31...♖xc7 and go on, there is no check-mate line here yet (e.g. 31...♕xc7 32. ♘h5+ ♔h7 33. ♕g5 ♗xe4 34. ♕h4 gxh5 35. ♕xh5+ ♔g7 36. g5 ♖h8 37. ♖f1 ♗g6 ∓. The only thing I can see is the perpectual checks, in case of 32...♕xd7 33. ♘h5+ gxh5 34. ♕g5+ ♔h7 35. ♕xh5+ ♔g7 36. ♕g5+ ♔h7 37. ♕h5+. Nevertheless, Black is not forced to capture the ♘, so the King recommends 33...♔h7 34. ♕g5?! ♗xe4 or 34.Tf1 f6. I guess that Black can protect him self yet. After 36.♕g5 there is no much way to recover the position, without some white mistake. |

| Jan-21-21 | | 5hrsolver: I also missed 45.Qg7
I had
42. Ne8+ Rxe8 43. Qf6+ Kh6 44. Qf4+ Kh7 45. Qxf7+ Kh6 46. Qxe8 Qxd4+ 47. Rf2
and white should win here because of material advantage and attack. Also in the actual game there is still the
matter of finishing the game after 45...Kh4
46. Kh2 Bxh3 47. Rf4+ Bg4 48. Qh6# |
|
| Jan-21-21 | | agb2002: White has a knight for a bishop.
Black threatens Qxd4+.
White can try to take advantage of the d-file with the maneuver Ne8+ (to distract the rook from the defense of f7) followed by Qf6. So 42.Ne8+: A) 42... Rxe8 43.Qf6+
A.1) 43... Kh6 44.Qf4+
A.1.a) 44... g5 45.Qf6+ Kh7 46.Qxf7+ Kh8 (46... Kh6 47.Rf6#) 47.Qxe8+ and mate in four. A.1.b) 44... Kg(h)7 45.Qxf7+ Kh6 46.Qxe8 (46.g5+ Kxg5 47.h4+ Kh6) 46... Qxd4+ 47.Rf2 wins the exchange. A.2) 43... Kg8 44.Qxf7+ wins.
A.3) 43... Kh7 44.Qxf7+ transposes to A.1.b.
A.4) 43... Kf8 44.Qxf7#.
B) 42... Kg8 43.Qf6 Rxf8 44.Qxf7+ transposes to A.2. C) 42... Kh7 43.Qf6
C.1) 43... Rxe8 44.Qxf7+ transposes to A.1.b.
C.2) 43... Kh6 44.g5+ (much quicker than 44.Qxf8) 44... Kh5 (44... Kh7 45.Qg7#) 45.Ng7+ Kh4 46.Qf4+ Kxh3 47.Rf3#. |

 | | Jimfromprovidence: It might have been worth a shot for black to continue playing with 45...Kh4, as it looks like 46 Kh2, below, is white's only winning move.
click for larger view <5hrsolver> posted a pertinent comment about 45…Kh4 as I was proofing mine. <Also in the actual game there is still the
matter of finishing the game after 45...Kh4 46. Kh2 Bxh3 47. Rf4+ Bg4 48. Qh6#> |
|
| Jan-21-21 | | 5hrsolver: <Jimfromprovidence: 5hrsolver posted a pertinent comment about 45…Kh4 as I was proofing mine.> I guess I beat you to it. lol.
In that line also after 47. Rf4+ if black plays instead 47...Kxg5 then 48. Qf6+ Kh6 49. Rh4# |

 | | gawain: I got the start of the winning combination but I worried that it was not conclusive enough. Black can fight on for a while. I forgot that what is conclusive on a Thursday is not the same as what is conclusive on a Monday or Tuesday. |
