| Sep-20-09 | | grz: How many moves ahead do you think Imbaud had calculated before the sacrifice? |
|
| Sep-20-09 | | Jedzz: 9. Nxe5 was fairly easy to spot — the position all but screamed for a Légal trap variation. After that came a seemingly endless succession of !! moves. Great game by white. |
|
| Sep-20-09 | | benjinathan: Well, that is the opposite of yesterday's puzzle. I think that a lot of people will get this. |
|
| Sep-20-09 | | RandomVisitor: 9...Qh4 10.Nf3 Qe7+ 11.Be3 0-0-0 12.0-0 might be best after 9.Nxe5, but white gets a pawn for free. |

 | | OBIT: Yeh, since this is a Sunday puzzle, it seemed likely the move was 9. Nxe5, but no way would I be able to work out all the critical lines to play this with any confidence in an OTB game. If I was playing someone 400 points higher than me, i.e. someone I expected to lose to anyway, I'd probably cross my fingers and risk it. Against a lower-rated player, no chance. I see this is a correspondence game, so for sure Imbaud worked everything out to mate before he mailed 9. Nxe5. I'll bet it took hours. |
|
| Sep-20-09 | | Anatoly21: Seeing 9.Nxe5 was easy, but it took me a whole five minutes before I found the crucial 12.Ne4+!, sacrificing the knight. After that I think, the rest is easy. |
|
| Sep-20-09 | | MarvinTsai: So cg has verified this game with Crafty? Could it end with less plies? Or will there be more struggling ahead? |
|
| Sep-20-09 | | goldfarbdj: I saw the idea of Nxe5 and Bxf7+, which is more than I usually do on a Sunday, but I got stalled at white's 12th -- Ne4+ didn't even occur to me. No way would I dare to play that OTB. (Of course, this wasn't OTB.) |
|
| Sep-20-09 | | Eduardo Leon: Yay! I saw it all!
<9. Nxe5!>
This move is very attractive. The problem is whether it's sound or not. <9. ... Bxd1>
Otherwise, black loses at least a pawn.
<10. Bxf7+ Ke7 11. Bg5+ Kd6> White has given up his queen, but he's achieved something more important: the black king can't go back home. <12. Ne4+!>
The only move that preserves the attack. White gives up yet another piece, but forces black to advance further with his king. <12. ... Kxe5 13. f4+ Kd4> Of course, not <13. ... Kf5? 14. Ng3#>. <14. Rxd1!>
Of course, not <14. Kd2?? Bxc2!>, and the black king escapes from mate. <14. ... Ke3>
It seems like <14. ... Qxg5 15. c3+ Ke3 16. fxg5 Kf4> (otherwise <17. 0-0>) lets the black king return home and remain a piece up, but it doesn't work: <17. Rf1+ Ke5 18. d4+ Kxe4 19. Kd2!>. <15. 0-0 Nd4>
The threat was <16. Rf3+ Kd4 17. c3#>. The following sequence is forced. <16. Rde1+ Ne2 17. Rxe2+ Kxe2 18. Bh5+ Ke3 19. Rf3+ Kd4 20. Bf7!!> The last finesse. After a combination that started in the ninth move, black will be finally mated with a pawn. |
|
| Sep-20-09 | | Milesdei: I had everything from 9.Nxe5 but got confused after 14...Ke3. I tried 15. f5+, but after Qxg5, 16. Nxg5 Nd4 17. O-O Nxc2, 18.Rf3+ Kd4, 19. Ne6+ Ke5 20. d4+ Kd6 white's attack runs out of gas. |
|
| Sep-20-09 | | LaFreak III: 16.Rfe1 is better than Rde1 |
|
| Sep-20-09 | | Eduardo Leon: More detail on <LaFreak III>'s move: <16. Rfe1+ Ne2+ 17. Kf1!> And mate is unavoidable. |
|
| Sep-20-09 | | syracrophy: There's another variation that can´t escape from analysis: 17...♔d4 18.c3+ ♔xd3 19. ♖d2+! ♔xe4 <19...♔e3 20. ♖e1#> 20. ♖e1+ ♔f5 21. g4#!

 | | An Englishman: Good Evening: As beautiful as the attack may be, this was too easy for a Sunday; in other words, I solved it. In fact, for the longest time I thought this might be one of those "trick" puzzles that CG sometimes inflicts on us, where the seemingly winning line actually loses. But no, it works. |

1.e4 ♘otes by Eric Schiller. d5 2.exd5 Nf6 3.Nc3 Nxd5 4.Bc4
Nb6 5.Bb3 Nc6 6.Nf3 e5 A rather brash move, sticking a pawn
in the middle of the board with only a single knight as
protector. In addition, the bishop at b3 has a clear aim at
the vulnerable f7-square. 7.d3 Bg4 8.h3 Bh5 9.Nxe5 A
brilliant move! A familiar theme, with the twist that ♗lack
has greater development than usual when the classic queen
sacrifice is used. Bxd1 10.Bxf7+ Ke7 11.Bg5+ Kd6 12.Ne4+ Kxe5
13.f4+ Kd4 13...♔f5 is a horrible blunder. 14.♘g3# mate.
14.Rxd1 The black king has been driven to d4, and the extra
queen is of no use. The king tries to hide on e3. Ke3
14...♕xg5 15.c3+ ♔e3 16.fxg5 also wins. 15.O-O A good
move! Nd4 White announced mate in 6. 16.Rde1+ Ne2+ 17.Rxe2+
Kxe2 18.Bh5+ Ke3 19.Rf3+ Kd4 19...♔e2 20.♖g3+ ♔e1 21.♖e3#
mate. 20.Bf7 The checkmate will be delivered by the pawns.
Nd5 21.c3+ Nxc3 22.bxc3# ♘ow, you may well think that this
game is composed. Especially when my source for the game
indicated it was dedicated by Mr. Wellmuth to the late
♙errier. The sparkling gem was created in the middle of a
World War, when there wasn't time or opportunity serious
tournament play, and I'll admit that the other offerings from
that year didn't impress me enough to set this aside, and
besides, it doesn't seem to be well known. Actually, it isn't
all that complicated, just long. ♘otice how few branches had
to be calculated. A very short computer analysis found the
move, but concluded that ♗lack might gain a slight
advantage. Of course an exhaustive search would have led the
program to the correct conclusion. Even after looking just 7
moves ahead, White gained the advantage. 1-0 |
|
| Sep-20-09 | | dzechiel: White to play (9?). Material even. "Insane."
It doesn't take long at all to spot the candidate move 9 Nxe5
This is a common mating theme in some chess openings (however, there is usually a black pawn on d6). But as the first few moves are very forcing, it seems like it should be played. 9...Bxd1
Otherwise drop a pawn for no compensation.
10 Bxf7+ Ke7 11 Bg5+ Kd6 12 Ne4+ Kxe5 13 f4+
This is the first time since move 10 that black has a decision to make. He should play 13...Kd4
Because 13...Kf5 is met with 14 Ng3#.
This is where I go off track. I considered
14 Rxd1
but was unable to see how the game would end.
Looking at the score I see this was a correspondence game and that means the players had more time than I did to work on this position. Insane indeed. Looking forward to Monday. |

| Sep-20-09 | | RandomVisitor: On the Perrier-Wellmuth game page we have this post: Oct-07-07 Calli: This game was published by Wellmuth in the original Golden Treasury of Chess (David McKay, 1943). It is given as a real game, not analysis. I believe both players were priests. If they lied about this game, then we all know where they are today :-o |

 | | LIFE Master AJ: Sunday; September 15th, 2009.
01:55 AM.
I have not looked at the solution yet ... I definitely had to set this one up on the chessboard. Of course the simple 9.0-0 could never be the answer, NOT on a Sunday! And I actually analyzed this line in my head ... and then played it out on the board (just to be sure) ... it leads nowhere either: 9.NxP/e5?!, BxQ/d1; 10.BxP/f7+, Ke7; 11.Bg5+, Kd6; 12.Bxd8, NxN/e5; 13.RxB/d1, NxB/f7;  So I am stumped. I guess I go to bed and lie there and torture myself a little more ... |
|
Sep-20-09
| | LIFE Master AJ: For the record, I have already spent about 45 minutes on this one ... |
|
| Sep-20-09 | | The17thPawn: Correspondence or not its still impressive for a player rated below expert level. Of course he may have had access to the 1917 game listed above. |
|
| Sep-20-09 | | melianis: There are some reasons why it is called Scandinavian DEFENSE. |
|
| Sep-20-09 | | gofer: After a few minutes Nxe5 is screaming at me, some of the permutations lead to mate if black accepts the queen sac and the rest seem to lead to a winning position. If black refuses the queen sac the white wins a quick pawn and suddenly most of black pieces are poorly placed, so probably the acceptance is the only option! 9 Nxe5 Bxd1
10 Bxf7+ Ke7
11 Bg5+ Kd6
12 Nd4+ Kxe5
13 f4 Kd4 (Kf5 14 Ng3#)
14 Rxd1...
14 ... Qd7/Qc8 15 c3+ Ke3 16 f4#
14 ... Qe7/Qf6 15 Kd7 mating with 16 c3+
14 ... Qxg5 15 Nxg5 seems to be winning...
But is there something better than 14 Rxd1?
Time to check... |
|
| Sep-20-09 | | gofer: 14 ... Qxg5
Black is a piece up for the two lost pawns and a horrible king position, but I cannot see a quick kill for white... ...anyone see something I have missed??? :-) |

| Sep-20-09 | | MenisfromVenis: <gofer: 14 ... Qxg5

16 0-0 Qh4 (to stop the mate)

18 Rd2+ Ke1
