 | | Gypsy: <Calli: ... Secondly, this is the incorrect score, he did not play 11...Kxe6 and get mated. ...> Lot's of folklore in old chess books. I just found this game, in the notes to Fischer vs Reshevsky, 1958 -- in Pachman's "Modern Chess Tactics". Pachman gives it also with the <11.Ne6! Kxe6 12.Qd5+...> finish. |

| Jun-20-18 | | zanzibar: The correct version of the game had made it to San Francisco within a year of its play: https://chroniclingamerica.loc.gov/... . |
|
| Jun-21-18 | | sudoplatov: I'd like to add the game Lachex vs J Nogueiras, 1990. (I was one of the program's authors.) The loser was not Jesus Nogueiras of Cuba but another J. Nogueiras from the US. |
|
| Jun-21-18 | | zanzibar: Whoa, on two counts....
https://chessprogramming.wikispaces...
1) Lachex was written in Fortran and assembler. (Betcha it wasn't that namby-pamby F9x/2k stuff either) 2) Wikispaces is closing. (Ouch for chessprogramming pages) |

| Dec-31-21 | | Brenin: Friday, and it's another Monday puzzle. The first move 10 Bxf7+ is obvious, and 10 ... Kf8 or Kh8 allow 11 Ne6, winning the Q, so 10 ... Kxf7. The follow-up could be 11 Qh5+, but why not 11 Ne6 anyway, since 11 ... Kxe6 allows 12 Qd5+ Kf6 13 Qf5 mate. After 11 ... Nf6 12 Nxd8 N(or B or R)xd8 White has won Q for B+N, a winning advantage. |
|
| Dec-31-21 | | mel gibson: 10. Bxf7+ was the first move I saw and then I had to check out 10. Ne6 It turns out that 10. Ne6
is a losing ply for White.
I got confused.

|
| Dec-31-21 | | Cheapo by the Dozen: Usually when a midweek problem seems this easy, I click through and discover a defense I had overlooked. But this felt like a Tuesday puzzle to me, if not Monday. 10 Bxf7+ and declining the sacrifice leaves Black in a material hole. 11 Ne6 ditto, but accepting the sacrifice gets Black mated in 2. |
|
| Dec-31-21 | | stacase: I had to laugh when I saw that Queenie was snowed in and had no place to go. If Black takes the Knight, I came up with this:
11...Kxe6
12. Qd5+ Kf6
13. Bg5+ Kg6
14. Qf5+ Kh5
15. Bxe7+ Kh6
16. Bxd8 |
|
| Dec-31-21 | | AlicesKnight: This shape is probably too well-known to be a Friday puzzle, however attractive it is. After Bxf7+ Kxf7; Ne6 Black must give up the Q or be mated. Compare T Tylor vs Koltanowski, 1929 |
|
| Dec-31-21 | | saturn2: After yesterday the next f7 sacrifice. Similar to Fisher Reshevsky. There was a Alejekin article on f7 sacrifices where he gives as an example one of his games against a certain NN . I did not find this game in the database though. |

 | | scormus: Overconfidence on my part meant I didn't look closely enough at 11 Ne6 Kxe6 and missed the crushing continuation. Instead I picked the knee-jerk 11 Qh5+?, thinking
either
... g6 12 Qxh7+ Kf6 13 Nd5+ Ke5 had to result in mate, surely? Yes, it does .... or 11 ... Kg8 12 Ne6+ wins the Q. Only it doesn't. I missed 12 .... Nf6 and then after the dust settles W is only about +1.0 No marks today |
|
| Dec-31-21 | | King.Arthur.Brazil: After found the sacrifice 10. ♗xf7+, however I missed the important move 11. ♘e6 first! I was searching for a continuation with move 11. ♕h5+ (bad and old players can't resist to give check!) which leads to nowhere. I could come back and check alternatives, but today is the last of the year, many things yet to do. Hope that Brazil keep on with right wing president, recovering our economy and doing best for our people (free from leftist demagogy and bandity). So, Happy new year everybody! |

 | | keypusher: I would have thought Walther von Holzhausen was too strong for a simul. |
|
| Dec-31-21 | | Tiggler: 11. Ne6 was a very clever move. I didn't see it, and so found nothing better than a draw. |
|
| Dec-31-21 | | johnnydeep: Astounded white didn't take the trapped black queen immediately. Even the engine says it's best move. |
|
| Dec-31-21 | | ruzon: <stacase: I had to laugh when I saw that Queenie was snowed in and had no place to go.
If Black takes the Knight, I came up with this:
11...Kxe6

| | keypusher: <johnnydeep: Astounded white didn't take the trapped black queen immediately. Even the engine says it's best move.> I'm astounded that you care in the slightest which of two completely winning moves White chose. In engine terms it's the difference between about +8 and +7.5, which in human terms is no difference at all. 12.Qh5+ g6 13.Nxd8+. |

|
| Dec-31-21 | | Brenin: <johnnydeep> White was probably hoping for a quick mate with 12 ... Kxe6 (or Kf6) 13 Qf5. Fortunately for him, after 12 ... g6, he can play 13 Nxd8 with check. After 12 ... Kg8, played by Black, White has nothing better than 13 Nxd8 Rxd8, with Q+P vs B+N, and more to follow after 14 Nd5. For a player of von Holzhausen's ability, that is an easy win, even against Tarrasch. |

 | | corneliussulla: an amusing trainwreck |
|
| Jan-01-22 | | 1stboard: In Irving Chernev's book 1000 best short games of Chess. Tarrasch's quickest defeat.
Black walks into a crusher with white's 11th move. Chernev does not show the rest of game but says Black has seen enough ..... |
