|Mar-10-10|| ||DarthStapler: Wait, there's no solution?|
|Mar-10-10|| ||whatthefat: Heh, nice one.|
|Mar-10-10|| ||MiCrooks: Nxe5 is playable, but certainly not a particularly good move. After Nxe5 White has to go in for f3. Black is fine here and can try for a long term advantage with something like Qh4+ since g3 loses immediately. But it is not clear how unsafe White's King will be after Ke2. Still, hardly the position you should be shooting for here.|
Some mentioned going back into normal lines with c3, but dxe5 seems to be a pretty decent try here. The key being that now Nxe5 leads to a White advantage after the sham sacrifice Nxe5! This leads to the following forced variation Bxd1 Bxf7+ Ke7 Nc6+ Kxf7 Nxd8+ Rxd8 Kxd1 where White ends up with a solid pawn plus.
Bxf3 Qxf3 Ne5 Qe2 gives White the two Bishops and a superior pawn structure (e5 vs d6). Best is probably dxe5 but there Qd5! leads to real problems for Black as well. Qxd5 is forced then bxd5 forces Nb4 Bxa8 Nxc2 Kd2 Nxa1 Nxe5 where White has restored the material balance and it is doubtful that the errant Knight will reemerge from a1 with his life. Black's current worry is his Bishop. The try Be6 looks reasonable attempting to free the Knight but Bc6 Kd8 Bd5 leaves Black in trouble again.
|Mar-10-10|| ||beenthere240: I wonder how gracious Bobby was. Or if he brayed with laughter.|
|Mar-10-10|| ||Uros Jankovic: "Patriot"
That would be a counting mistake (white is down a piece). Play might continue: 10...Nf6 11.Qd1 (11.Qh3 Nxc2+ 12.Kd1 Nd4 13.f3) 11...b4 stopping a c3 trap. There's no sense going very deep into this, however, since white has no compensation for losing a piece.
I still believe that two pawn for a piece and semi open f file offer some counterplay. Wouldn´t mind playing white against you in that position. Thanks for your comment...
|Mar-10-10|| ||Quentinc: Well, this sure spoiled me. A medium easy and nothing I tried for White worked -- I was sure I was overlooking something ridiculously obvious. Since Fischer was only around 11 when this was played, I didn't see that as any reason to conclude that this was a spoiler.|
|Mar-10-10|| ||Patriot: <Uros Jankovic> I stated there was no compensation for the piece, which is incorrect. As you say white has two pawns for a piece, but two pawns generally isn't enough compensation unless there is dynamic potential. Otherwise, if black can avoid complications he should eventually win.|
|Mar-10-10|| ||awfulhangover: Hehe, it's wednesday, and after a short while I gave up. Found nothing and felt stupid. Puh..., it WAS nothing!|
|Mar-10-10|| ||ruzon: Someone subscribe me to firstname.lastname@example.org! As someone who works in vision (computer, not human), I clearly appreciate its importance. Get well soon, David.|
|Mar-10-10|| ||turbo231: <benjinathan: cue a thousand posts which shows positions were Rybka couldn't solve the puzzle>|
Please forgive my ignorance but how does one cue a post for that,or cue a post in general? I would be very interested in those puzzles,it would give me something to do. I enjoy projects of that nature.
|Mar-10-10|| ||johnlspouge: Wednesday (Medium/Easy)
J Altusky vs Fischer, 1954 (7.?)
White to play and win.
Material: Even. The Black Ke8 has 2 legal moves. The White Bb3 attacks f7, so the pin of the Black Bg4 on Nf3 might be broken by check. The combination is a boomerang, however, because Black has a resource, so White should play a developing move, e.g., 7.Be3.
Candidates (7.): Bxf7+
7.Bxf7+ Kxf7 8.Ng5+
Now, the boomerang:
8…Qxg5 9.Bxg5 Bxd1 10.Kxd1
Black has N for P. On move 9, other moves just leave Black up B for P.
|Mar-10-10|| ||WhiteRook48: 7 Bxf7+??
i chose 7 Nxe5?? stupidly, the idea was 7...Bxd1 8 Bxf7+ Ke7 9 Nxc6+ Kxf7 10 Nxd8+ Rxd8 11 Kxd1. I overlooked 7...Nxe5
|Mar-10-10|| ||patzer2: <Turbo231> I think the suggestion is to do a search on Kibitz (button above) here to look for games and "positions Rybka had difficulty solving."|
Also, you might look at the neat description provided by User: zanshin on his profile for a summary of the kinds of positions Chess programs generally have difficulty solving.
|Mar-10-10|| ||turbo231: <patzer2>
Thank you very much, this could get interesting.
|Mar-10-10|| ||Steffen23: I have solved the puzzle. The correct move is Bg5. [Event "Offhand Game"]
[Event "Offhand Game"]
[Site "New York, USA"]
[White "Jacob Altusky"]
[Black "Robert James Fischer"]
[Result "0-1" (1-0)]
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 d6 5.d4 b5 6.Bb3 Bg4 7.Bxf7+
(7.Bg5 f6 8.dxe5 fxg5 9.exd6 Bxd6 10.Qd5 Qd7 11.Nxg5 Nf6 12.0-0
(12.Qf7+ Qxf7 13.Bxf7+ Kf8))
7...Kxf7 8.Ng5+ Qxg5
|Mar-10-10|| ||Steffen23: Addendum: White now has compensation for its bishop with the winning of 3 pawns|
|Mar-10-10|| ||CitricAcid13: Steffen23, 7.Bg5 loses to 7...Bxc3 (8. Bxd8 Bxd1 and black is up a piece). Taking the bishop on f3 with the pawn or the queen gives up the bishop on g5 to the queen. 0-1|
|Mar-10-10|| ||BraveUlysses: I got sucked in by this one, sneaky CG! Nice one. But only because it was presented as an "Easy/medium" puzzle... The hint was in the 'medium' bit- if it was just the classic "B takes, N check discovers the QxB" wheeze it would hardly have been more the "easy" would it?|
|Dec-28-10|| ||kingfu: If I was Altusky, I would change my name to NN!|
|Dec-16-11|| ||Albion 1959: Amazing that an offhand blitz game by a 10 or 11 year old Fischer in 1954, that lasted only 8 moves, should attract so many comments and the subject of so much analysis !!|
|Dec-16-11|| ||ughaibu: Have you read the comments? There's nothing amazing about it, it's exactly as one would expect.|
|Dec-16-11|| ||FSR: <gofer: I looked at this in the morning and wrote the following ...|
7 dxe5 dxe5
8 Qxd8+ Rxd8
...which I saved to a .txt file and gave up for the day...>
9...Rd1 is mate.
|Dec-16-11|| ||Penguincw: Jacob Altusky didn't expect the queen taking the knight.|
|Feb-17-12|| ||ArtsewS: I made a Youtube vid out off this one:
|Jul-28-12|| ||cyrusmari: After 8.Ng5 Qxg5+...
9.Bxg5 Be7 10.Qxg4 Nxd4 11.Na3 Ne6 12.Bxe7 Nxe7 13.O-O-O g6 14.g3 h5 15.Qf3+
Kg7 16.h4 Rhf8 17.Qe3 Nd5 18.Rxd5
