 | | johnlspouge: <patzer2>, thanks for your comments on the midgame, which I found very instructive. If you need some additional reason to find Fischer's chess prowess amazing :), the puzzle position left me (like some others) with the initial impression that the move Ke4 was so good (centralize the K in the endgame!), it had to be there, somewhere in the scoresheet. After I calculated some variations leading to the K+RP vs. K ending, I was amazed to find that the move Ke4 led to the RP draw. Fischer's K needed to be on the Q-side: throughout the endgame and much earlier than the puzzle position, guess in which direction it was relentlessly trekking? |

| Jan-24-08 | | ChessNe1: BAM, i got this one quickly for a change! 39...Kf6 was a boo boo, yaking the B out of defensive action! |
|
| Jan-24-08 | | TrueBlue: I believe the obvious Ke4 works. |
|
| Jan-24-08 | | just a kid: I swear I haven't looked at this yet.I think 40.d6! Ke6 41.g5 a5 42.g6 Bf6 a4,or b4 43.g7 Kf7 44.d7,and White wins 1-0.Now to check this took me about 5 minutes to make sure everything worked,but I got this in about 1 minute. =) |

| Jan-24-08 | | just a kid: Sweetness 4 for 4!!!! I thought I wasn't that good. |

| | johnlspouge: <TrueBlue: I believe the obvious Ke4 works.> I was imprecise. The move 40.Ke4 might not lead to the RP draw, but I did prove to my satisfaction that the variation 40.d6 Be5 41.Ke4 Ke6 leads to the RP draw. This late in the week, unfortunately, I have little interest in proving that the second-best move wins. |

 | | DarthStapler: I've really been doing poorly this week. I kept thinking Nd4 to block the bishop |

 | | patzer2: <johnlspouge> You're welcome. I was surprised to see that even 20 years after his world championship victory, Fischer's play remained so amazingly strong. Of course one could argue the 55 year old Spassky had lost a bit of his calculating skill, and was not quite the opponent he was 20 years earlier. |
|
| Jan-24-08 | | TrueBlue: johnlspouge, proofs in chess are very hard. That's why I stick to proofs in other disciplines :) Chess is after all just a game, not a science. |
|
| Jan-24-08 | | GannonKnight: I'm with DarthStapler. I had Nd4 as well. |

 | | MostlyAverageJoe: <Chesstalesfan: MostlyAverageJoe: Today's 2nd best (+3.91) 40. Ke4 ... 3. (+1.57)40.Kc2 ... And, of course, the best move: 1. (+4.09) 40. d6 ...
Please, do you know what +4.09 or +3.91 or +1.57 mean? how is the quantification made?> The numbers express the advantage on linear scale, where 1.00 represents one pawn. The are computed by software as a combination of the material difference and positional advantage computed by various heuristic methods, depending on the software being used (mine is Hiarcs 11.2). Different programs can differ in their assessments of the same position by 0.50 or more. In most cases, Hiarcs' score > 2.00 implies a win for white, while score < -2.00 implies a win for black. The in-between values are frequently misleading, although < -1.00 or > 1.00 in middle game might evolve into a win with deeper analysis. |
|
| Jan-25-08 | | Chesstalesfan: Dear MostlyAverageJoe, thanks a lot for this information! |
|
| Jan-25-08 | | brainzugzwang: Thanks, <johnlspouge> -- that helps, although my thinking was more along the lines of the difficulties White faces in getting both Black pawns wihtout trading off the RP or the N, especially with the Black K nearby. |

| Jan-25-08 | | jovack: Why do people insist on explaining how long it took them to get the puzzle?
Insecurity is an amusing thing. |
|
| Jan-25-08 | | RookFile: Well, today's puzzle is actually an excellent example of what Nigel Short was talking about. You play over a Fischer game, and after the fact, the moves seems so simple. However, if you try and find Fischer's moves on your own, you find out it isn't quite as simple as you thought. |

| Jan-31-09 | | WhiteRook48: Fischer did great in exploiting his passed pawns |
|

 | | kevin86: How about this odd finish: 43... xg7 44  xg7+  xd6. White will eventually queen his lowly a2 pawn and will win!!! |
|
| May-26-09 | | WhiteRook48: two bishops vs two knights?! |
|
| Mar-10-11 | | hottyboy90: Lovely technique by Fischer although I got this one fairly quickly but I would never had been able to reach a position like that against someone of Spasskys caliber so I will just shut up now. Enjoyed the endgame very much all the same. |
|
| Mar-12-11 | | Damianx: Amazing the best ever he wins this on moves 18/19/20 |
|
| Mar-12-11 | | hottyboy90: really? them moves seemed pretty insignificant to me. I think the decisive advantage for Bobby came after 28...Rxe3 |
|
| Feb-04-13 | | RookFile: One of history's great Ruy Lopez players relies upon playing d3 rather than the more customary d4 break. In doing so, he preserved the option of a later d4, and kept Spassky guessing. |
