| Oct-03-08 | | Marmot PFL: The rook moved jumped off the board at me. Years ago i won a game like that when my opponent and his kibitzer friends all thought i was lost. |

| Oct-03-08 | | johnlspouge: Friday (Difficult): Forintos vs Tomovic, 1957 (35.?) White to play and win.
Material: Even. The Black Kh7 has 1 legal move. The White Kh3 is facing a mate-in-2 beginning with check. The candidates for counterattack are therefore narrowed to checks; those for direct defense, to 35.Qf4. Candidates (35.): Rh8+, Bxg6+, Qf4
35.Rh8+ Kxh8 [Kg7 36.Qf8#]
36.Qf8+ Kh7 37.Qxf7+ Kh8 38.Qf8+ Kh7 39.Bxg6+ Kxg6 40.Qg8# |

| Oct-03-08 | | TheaN: 4/5
Geez what a Friday letdown... normally I'd quit a week after missing a Thursday but this was TOO easy. Have to admit that Bxg6† took me a while, and I went down the hill with 35.Bxg6† before noticing it. <35.?>
White: a4, b2, e5, g3, h2, Bd3, Rd8, Qb3, Kh3
Black: b7, b6, f7, g6, h6, Bf3, Ra5, Qg1, Kh7
Candidates: Rh8†, Bxg6†, [Rh8†]
-ML-
Ok, critical is to spot that the variation:
35.Bxg6†? Kxg6 (fxg6 36.Qe7‡ 1-0) 36.Qd6†! Kh7! (Kg5 37.Qf6‡ / f6 37.Qxf6† Kh7 38.Rh8‡ / Kg7 37.Qf6† Kh7 38.Rh8‡ 1-0) 37.Qd3† Kg7 38.Qxf3 Rxe5 is drawish, so that it must be the other obvious move: <35.Rxh8†> and it works, although the mating sac might not be too easy to spot. But difficult, seeing it's a puzzle, no. /A\
<35....Kg7 36.Qf8‡ 1-0> /B\
<35....Kxh8 36.Qf8† Kh7 37.Qxf7†> take note that this removes the defense of g6: critical, as this allows the Bishop in. <37....Kh8> it was this position nonetheless that kept me troubling: <38.Qf6† Kg8 (Kh7 39.Qxg6† Kh8 40.Qh7‡ 1-0) 39.Qxg6†<>> looks crushing, but the Ra5 and Bf3 do not allow the entrance of Bd3 by means of Bc4†. With careful play, Black holds with: <39....Kf8 (Kh8 40.Qh7‡ 1-0) 40.Qf6† Kg8 (Ke8 41.Bg6† Kd7 42.Qd6† Kc8 43.Bf5‡ 1-0) 41.Bc4† Rd5!<>> if 41....Kh8 42.Qf7‡ and 41....Bd5 42.Bxd5† Rxd5 43.Qe6† although Black seems to draw with 43....Kg7! 44.Qxd5 Qe3†!...but I'm not sure. But after 41....Rd5!, 42.Bxd5† (Qe6†? Kg7 43.Qxd5?? Qg2† 44.Kh4 Qxh2‡ 0-1) Bxd5 White would want to keep perpetual. Anyways, White should just get his Bishop in via g6, and voila, he can do that almost instantly. <38.Qf8†! Kh7 39.Bxg6†! Kxg6> and what results is a pure mate with a Queen, two pawns and an enemy pawn. <40.Qg8‡ 1-0> |
|
| Oct-03-08 | | YetAnotherAmateur: To show how thoroughly out of shape I am right now, I went with: 35. Bxg6+ Kxg6 (fxg6 Qd7#)
36. Qd6+ Kh7 (... Kg5 36. Qf6#, ... Kg7 36. Qf6+ Kh7 38. Rh8#) 37. Qd3+ Kg7 (... f5 38. Qxf5+ Kg7 39. Qf6+ Kh7 40. Rh8#) 38. Qxf3 Rxe5
diffusing the mating threat. |
|
| Oct-03-08 | | TheCap: I did not see the 4 move mate, but I saw the 3 move "mate", which of course was a draw, BUT: I would have seen that after I moved Qf8# !!!
Sounds weird?? Yes, but sometimes one has to storm into an attack EVEN if the outcome is not 100% clear, because of time pressure and too many variants, then think on the fly and if it is lost one can at least say: I have tried and given it my best shot rather than standing back in safety waiting for the draw... THE CAP HAS SPOKEN |

| Oct-03-08 | | stardust762: This one was not so difficult at all. White was also under attack, black was threating 35...Qg2+ and mate to follow. White has no choice but attack with check.
For example, if 35.Qf8 (threating 36.Qg8#)then 35...Qg2+ 36.Kh4 Qg4# 0-1
In this line, there was only two options for white, Rh8+ or Bxg6+ (which leads to a draw after 35...Kxg6). |
|
| Oct-03-08 | | The Rocket: Difficult? I dont think so bacically all the moves were forced and easy for me to spot. the first move for white should just pop up to a good player right away since black is threathening mate in one so white has to check till mate.... and then calculating that sacking bishop leading to mate shouldnt be to hard. What a great way to win a game as white!

| Oct-03-08 | | chessdr: Instead of 33. ... Bxf3 (?) I think 33. ... f5 wins in just a few moves. |
|
| Oct-03-08 | | stardust762: <chessdr: Instead of 33. ... Bxf3 (?) I think 33. ... f5 wins in just a few moves.> If 33...f5, then 34.exf6 (en passant). |
|
| Oct-03-08 | | chessdr: D'oh...except for that. Right. |
|
| Oct-03-08 | | 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 | | kevin86: A version on the same theme is the queen mate by:

| 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... |
|
| Oct-03-08 | | 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. |
|
| Oct-03-08 | | 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. |
|
| Oct-03-08 | | 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. |
