 | | kevin86: A nice forced mate. An open-ended epaulette mate. Instead of being blocked by his own pieces,the queen and pawn produce a flower-like pose. The queen guards f7 and h7;the pawn f5 and h5. |

| Oct-03-08 | | melv: Good mating pattern to remember. |
|
| Oct-03-08 | | YouRang: Drat. I found the first 3 moves, and was pleased that I could force a perpetual, lol. Didn't notice that a win was hanging there to be plucked... :-( |

 | | Jimfromprovidence: Black messed up with 32…Qg1+?. It was one move too early. He should have played 32…Rxb5 first, then, after 33 Qxb5, now 33…Qg1+.
click for larger viewBlack has his own threats; there’s a lot of pressure on the white king now. |

 | | playground player: Keep the Black King in check, and you're bound to win--but don't let up, because the White King is about to get nailed. But doesn't 35.Bxg6+ lead to a win for White? How can Black answer? a) 35...fxg6: Can't do that! 36.Qe7#
b) 35...Kxg6: Oops--my bad. The Black King escapes into perpetual check, and White has to settle for a draw. Didn't see that, first time I looked. So Rh8+ was right, and was the only right move. *sigh* |

| Oct-03-08 | | Miachonzinho: Bxg6 wons too. Right?
35. ♗xg6 ♔xg6 (35. ... fxg6 36. ♕e7#) 36. ♕d6
Them
a)36. ... ♔g7 37. ♕f6+ ♔h7 38. ♖h8#
b)36. ... ♔h7 37. ♕d3+ ♔g7 38. ♕xf3, avoiding mate, with a good end after 38. ... ♖xe5 avoiding the mate 39. ♕c3 takes the ♖ook (39. ... ♕f1+ 40. ♔h4 ♕e1+ 41. ♕xe1 ♖xe1 and white have a won end [in big part because of the doubled pawns on b ]) My analisys... |

 | | patzer2: For today's Friday puzzle solution, White plays the decoy sham sacrifice 35. Rh8+!! to initiate a mating attack. A second decoy, 39. Bxg6+!, finishes the combination with a mate-in-two. |
|
| Oct-03-08 | | number 23 NBer: Due to my inner brilliance, I managed to get to move forty but missed the mate in 1. |

 | | fm avari viraf: Though, it's a difficult puzzle but the answer looks very conspicuous to me 35.Rh8+ Kxh8 36.Qf8+ Kh7 37.Qxf7+ Kh8 38.Qf8+ Kh7 39.Bxg6+ Kxg6 40.Qg8# |

| Oct-03-08 | | Super Chess Man: This was rather an easy puzzle today ! |
|
| Oct-03-08 | | Geronimo: I usually have to set up my board to figure out friday, saturday and sunday puzzles, but this one jumped out at me. I know that in my games I tend to sacrifice a bit too readily (inspired by Tal, what can I say...). Once you realise that white also is under a mate threat than you know to look for forcing moves. The real key here is 39.Bg6. Without that, no real point. |

 | | agb2002: Black threatens:
A) 35... Qg2+ 36.Kh4 Qxh2 mate.
B) 35... Bd5 defending his KBP and Qe3+ winning the bishop. C) 35... Rxe5
Let's consider the most forcing moves
A) 35.Rh8+
A.1) 35... Kg7 36.Qf8 mate.
A.2) 35... Kxh8 36.Qf8+ Kh7 37.Qxf7+ Kh8 38.Qe8+
A.2.a) 38... Kh7 39.Qxg6+ Kh8 40.Qh7 mate.
A.2.b) 38... Kg7 39.Qxg6+ Kf8 40.Qxh6+ and after a few checks white can force a position with his queen on f6 and the black king on g8. Then Bc4+ wins the black bishop and rook because ... Kh7 loses to Qf7. The resulting queen ending should be a victory for white. B) 35.Bxg6+
B.1) 35... fxg6 36.Qe7 mate.
B.2) 35... Kg7 36.Qf8+ Kxg6 37.Qg8 mate.
B.3) 35... Kxg6 36.Qd6+ Kh7 (otherwise mate in two moves) 37.Qd3+ Kg7 38.Qxf3 Rxe5 and I don't see an immediate win. I'd go for line A). Time to post and check. |

| | agb2002: I didn't see Bxg6+ because I thought that the queen alone was not enough to deliver mate. But the queen was not alone... |
|
| Oct-03-08 | | Yodaman: Why not start this puzzle on move 34 instead of 35? It's still a force mate and that would make it Friday difficulty. I got a Friday faster than I ever have before yet I didn't get yesterdays. They should have switched the two puzzles, this one was easy. |
|
| Oct-03-08 | | Kings Indian: Had to be a forced mate. That always makes a bold strategy a given. The rest was very pretty, but a bit predictable for Friday. Kings Indian's dad |
|
| Oct-03-08 | | Woody Wood Pusher: 38.Qf8+ was the hardest move to find IMO |
|
| Oct-03-08 | | VooDooMoves: <Miachonzinho> After 35. Bxg6+ Kxg6 36. Qd6+ Kh7 37. Qd3+ Kg7 38. Qxf3 Rxe5 39. Qc3 Qe3+! and white cannot avoid the queen trade as it allows black a perpetual. 40. Kg2 (or 40. Qxe3 Rxe3+ and 41...Rb3) 40...Qe2+ 41. Kg1 Qe3+ 42. Qxe3 Rxe3 43. Rd7 Rb3 44. Rxb7 Rxb2 45. a5 b5 46. a6 Ra2 47. a7 b4 and now a trade of pawns seems likely and with the only pawns left all on one side of the board a draw seems likely. 1 line runs 48. Kf1 b3 49. Ke1 b2 50. Kd1 b1=Q+ 51. Rxb1 Rxa7. |

| Oct-03-08 | | newzild: Okay, I'm following Dzchiel's method, which is to write my comments in Notepad and paste them across, so I don't actually know what the move number is... Assess the position: Both sides are attacking. Black threatens 1...Qg2+ and 2...Qxh2++. This rules out a lot of first moves for white. Candidate moves:
1.Bxg6+
1.Rh8+
1.e6
Let's assess 1.Rh8+ first, because black has only one reply. 1.Rh8+ Kxh8
2.Qf8+ Kh7
3.Qxf7+ Kh8
4.Qf6+ and now...
4...Kh7
5.Bxg6+ Kg8
6.Qf7+ Kh8
7.Qh7++
or...
4...Kg8
5.Bc4+ Bd5
and white is stymied.
But white can win the black bishop and chew up all black's K-side pawns in this fashion: 4...Kg8
5.Qxg6+ Kf8
6.Qxh6+ Ke8
7.Qe6+ Kd8
8.Qf6+ K any
9.Qxf3
Is this the winning sequence? I suspect not. But my girlfriend is getting grumpy at me for being on the 'puter for more than 20 minutes. So it's DEFINITELY time to check... |
|
| Oct-03-08 | | newzild: ..Grrr!
I got the key but missed the simple mate, although I think my line wins in the long run. |
|
| Oct-03-08 | | DarthStapler: I got the first three moves |
|
| Oct-03-08 | | I Offer You A Resign: I got it!!! Wooo! I can't believe it! LOL. Man I feel so good. Unfortunately, i usually can't get the other ones >.< |
|
| Oct-03-08 | | MostlyAverageJoe: According to my engine-based evaluation, the difficulty of this puzzle is almost exactly on the average Wednesday level. This assessment appears to be confirmed by the fact that my 8-year old son figured it out as well after a bit of thinking (Thursdays and later puzzles are usually too difficult for his 1000 ELO rating). |

| Oct-08-08 | | Everyone: <braimondi> Yesterday will be so much more hard than today... |
