| Aug-16-04 | | Kaspy2: The "Bremen System" is named after the hometown of Carl Carls (Germany), who had worked it out and was a successful practitioner. Probably even Bobby used his study material. |

| Apr-11-05 | | Dick Brain: Did Fischer miss a win in the endgame around move 37-39 or so? It seems that if Whites a-pawn were to fall then Black's a-pawn would waltz in for the queen with his two super bishops. |
|
| Sep-05-07 | | TheaN: You should throw that into an engine... it's very hard to analyze that precisely. Byrne did try to avoid any unwanted capture of his a-pawn (even a sac could prove fatal). I like the final position, which I can analyze without an engine: 48....Kxf7 49.Be1 Bxb4 50.Kxg3 (Bxa4?? Bd6) a3 51.Bb3 Kg5 52.Kg2 h5 53.Kh1 1/2 1/2. |
|
| Jul-13-08 | | ounos: <Bxa4?? Bd6> Bxa4 is fine to draw (easiest is Bd7 controlling h3 forever) |

Black will have better position but winning is not easy. |

| Aug-13-11 | | goodevans: To any of the World's nations that participate in cricket, "duck" is synonymous with zero, so I was rather surprised to see this pun associated with a draw. I'd like to think that there's something more behind the pun than merely one player having the name Donald. If not then I would dub the pun rather a lame duck! |

 | | HeMateMe: I thought the pun is a reference to "Fischer Fear", that people were already starting to see that this kid was special, especially after the
"Game of the Century", played against none other than Donald Byrne. Maybe the pun refers to the exchange sacrafice, followed by a king side attack, as in "Look out! Duck!" |

I meant may be black could try to do that with 38...h5 or 38...Bb3 instead of <38...g3> which although opens for the B to h3, however it opens for the opponent B to f3 and the long diagonal and pushes g pawn away from h pawn support early. Black will have better position but winning is not easy. |

| Aug-13-11 | | DrMAL: <Dick Brain: Did Fischer miss a win in the endgame around move 37-39 or so?> 38...g3 was clearly a mistake, the best is to use pawn on g4 to block the diagonal and push 38...h5! This appears to win whether white goes 39.Rc5 or others like 39.d4 but I will put it on Houdini to verify. It seems 39.Rc5 is white's best and loses to 39...Be5! but maybe to 39...h4 as well. |
|
| Aug-13-11 | | DrMAL: Yes, after 38...h5! white's best is 39.Rc5 and 39...Be5! is winning but 39...h4 is not. This is a great game to study! After 39...Be5! white's best is 40.d4 Bxd4 41.Rxh5 Bb2 42.Rg5 Bxa3 43.Bxg4 Bc4+! 44.Be2 Bb3 45.e5+ Kc7 - +

click for larger viewBlack has passed pawn on h4 and superior king placement but with opposite color bishops progess cannot be made (e.g., 44...Kd6 45.Ke2 Bc1 46.Kd3 Bxa3 47.Kc3 Bc1 48.Bh3 Bf4! 49.Kb2 and black cannot move the king far because of the pawn on b5). |

|
| Aug-13-11 | | Michael1234567891011: according to rybka, black missed 22. bd5 which gives an eval of -1.72. Probably winning for black...oh well an interesting game nonetheless |
|
| Aug-13-11 | | DrMAL: <Michael1234567891011> Yes, 22...Rg4 was an earlier mistake. Not sure if 22...Bd5 wins but 22...Bxa2 probably does. How long did this compute? I will let it compute on Houdini awhile. |
|

 | | LIFE Master AJ: <M123> Its seems you are correct. I did not check it with Fritz 12, but 22...Bd5; looks very strong. |
|

| | LIFE Master AJ: Interesting game ... I don't get the "Donald Duck" stuff ... will someone please draw me a picture? |
|
| Aug-14-11 | | DrMAL: Houdini_15a_x64: 29/82 9:35:50 149,573,929,001
+2.14 22. ... Bd5 23.f3 Bxf3 24.Rf1 Qg4 25.Rbe1
+2.05 22. ... Bxa2 23.Ra1 Bd5 24.f3 Bxf3 25.Rf1
With 22...Bd5 white also loses a second pawn for the exchange but opposite color bishops result 23.f3 Bxf3 24.Rf1 Qg4 25.cxd6 Bxd6 26.Rbe1 h5 27.Rf2 Qg3 28.Re6 Rxh4 29.Rxg6+ Qxg6 30.Rxf3
click for larger view Black can still win with a mistake from white, but otherwise I don't think a win can be had. With 22...Bxa2 play is similar except black gains three pawns at first 23.Ra1 Bd5 24.f3 Bxf3 25.Rf1 Qg4 26.Bxd6 From here, white's best is to give back the exchange as before 27.Rxf3 Rxf3 Now when the endgame results and one pawn is gained back, the pair of extra pawns are connected 28.Qe2 Rf4 29.Qxg4 Rxg4 30.Rxa5 Rxh4 31.Ra8+ Kg7 32.Rd8 Kf6 33.Rd7 Ke6 34.Rxb7 c5
click for larger viewI don't think this can be won without an error by white either, but with the connected passed pawns black has better chances. Computer evaluations are only useful when variations are played out with strong knowledge of chess. |

I think the "Donald Duck" thing is that Donald Byrne "ducked" a bullet by achieving the draw! So the pun "Donald Duck".... |

| | LIFE Master AJ: Ahhh, gotcha. (Thanks.)
I was thinking something more arcane, but that makes sense. |
