<Isn't even the pawn endgame won for him from the beginning? What about 47.g4 instead. Looks winning with that outside passed pawn he's planning to get.>
It does not look so easy to me, because White may be left with a wing pawn. For example, the simple 47. g4 a5 48. f5+ gxf5 49. gxf5+ Kf6 50. Kd5 c4 51. bxc4 bxc4 52. Kxc4 Kxf5 is not enough to win, since Black's king heads for c8 with a draw.
Maybe 49. g4 (instead of the game's 49. g3), with the continuation 49. g4 Kd6 50. f5 gxf5 51. Kxf5 c4 52. bxc4 bxc4 53. Ke4 c3 54. Kd3, and now White's king wins the race to capture the a-pawn and reach b7 before Black's king reaches c8.

Yes, but maybe with the preliminary 48.a4. Most moves lose in elementary fashion, but there is a tricky line:
48.a4 b4 49.Kd3 Kd5 50.g5 Ke6 51.Kc4 Kf5 52.Kxc5 Kxf4 53.Kb5 Kxg5 54.Kxa5
Kf4 55.Kxb4 g5
and now 56.a5? g4 57.a6 g3 58.a7 g2 58.a8=Q g1=Q might not win, actually DOES not win according to tablebases, although there might be some winning chances in practical play, but instead
wins. (or 56.Kc3) Also tablebase-checked. The idea is that 56..g4 57.Kd3 g3 58.Ke2 is simple, so Black must misplace his king. For example 56..Kf3 and NOW start moving the a-pawn because White is going to queen with check. Or 56..Ke3, both pawns queen, and White wins with 61.Qa7+ winning the queen. Neat eh? :)
Or 48..bxa4 49.bxa4 Kd6 50.f5 gxf5+ 51.Kxf5 c4 52.Ke4 winning without complications.
In your line with 49.g4 Kd6 50.f5 better must be 50..g5 and it looks like a draw (not sure).
|Dec-21-04|| ||beatgiant: <acirce>:
Great job. I agree with your analysis. But Black still has the defence 47. g4 Kd6, and I have not yet been able to prove a win against this. Some unsuccessful tries (after 47. g4 Kd6) are 48. f5 g5!, or 48. g5 Ke6 49. a4 c4 50. bxc4 bxc4 51. Kd4 Kf5, or 48. a4 Ke6 49. a5 Kd6.
I'm not sure whether White can win or not, but I do say it's not simple.
|Dec-21-04|| ||Minor Piece Activity: If anyone is interested for the record I read that a GM analyzed 55. g6 (the move Fischer obviously should have played) to a draw. |

47.g4 Kd6 48.f5 g5 and now, unlike in your initial line with g4 only after 47.a4 Kd6 48.a5 Ke6, when White is actually in zugzwang as it seems, here 49.a4 is effective. I don't even see a trick, the win seems fairly straightforward. For example 49.a4 bxa4 50.bxa4 a5 51.Kd3 Kd5 52.Kc3 Kd6 53.Kc4 Kc6 54.f6 Kd6 55.Kb5 Ke6 56.Kxc5 Kxf6 57.Kb5 Ke5 58.Kxa5 Kf4 59.Kb4 Kxg4 60.a5 and White queens in time. I would say it indeed seems Fischer had a win.
|Dec-21-04|| ||beatgiant: <I would say it indeed seems Fischer had a win.> Another great job of analyzing this. I was thinking something like 47. g4 Kd6 48. f5 g5 49. a4 b4 50. Kd3 Kd5 51. f6 Ke6 52. Kc4 Kxf6 53. Kxc5 Ke5 and both sides queen after 54. Kxb4 Kf4 or 54. Kb6 Kf4. But now I think White would win with 51. a5, putting Black in zugzwang. |
|Dec-22-04|| ||beatgiant: For completeness, I note that 47. g4 b4 48. f5+ gxf5 59. gxf5+ Kf6 60. Kd5 and White wins all the queenside pawns for his f-pawn. |
The trap here would be 47. g4 b4 48. Kd3? Kd5 and I can't find a win anymore: 49. f5 g5! 50. f6 Ke6 51. Kc4 Kxf6 52. Kxc5 Ke5. Or 49. g5 Ke6 50. Ke4 a5! and now 51. f5+ gxf5 52. Kf4 Kf7 53. Kxf5 c4, or 51. Ke3 Kf5 52. Kf3 c4.
There's also another trap in <acirce>'s earlier line with 47. g4 a5 48. a4 b4 49. Kd3 Kd5 50. g5 Ke6 51. Kc4 Kf5 52. Kb5? (correct is 52. Kxc5 which wins with the tricky king maneuver as <acirce> gave earlier) 52...Kxf4 53. Kxa5 Ke4! 54. Kb5 Kd4 55. a5 c4.
So I agree with <acirce> that Fischer missed a win, albeit a moderately tricky one, with 47. g4!
Interestingly, after his 47. a4?, it seems too late to win with 48. g4 Ke6 49. g5 Kd6, because Black has the the threat of ...c4, or with 49. g4 Kd6 50. f5 g5 with the unusual zugzwang mentioned earlier by <acirce>.
|Dec-22-04|| ||drukenknight: you are massive end game player. I have to say:
1) thanks to you and other guy for playing out that Capa/Corzo game after a mere suggestion;
2) are you using pc program and what do you think of them?
3) what books etc. to you recommend to polish this aspect of someone's game?
|Dec-22-04|| ||beatgiant: <drukenknight>:
I'll respond to your questions soon in the Kibitzer's Cafe.
|Mar-02-07|| ||perfidious: As David Levy once wrote about Fischer, his active style had a tendency to relatively produce few endings that required great technique; he then mentioned the games Fischer-Portisch, Stockholm 1962 and Fischer-Tal from Curacao.|
From personal experience facing GMs in both games at regular time-checks (including a few who were quite strong enough,if not the great players named above), and rapid games with, among others, Tal, the endgame play will always tell the story.
|Jul-29-07|| ||actionhero56: 55.c5!!! I always knew Fischer was a tactical genius|
|Aug-14-07|| ||RookFile: He had a hallucination, of course.|
|Jun-17-09|| ||jsheedy: Anyone think of 50. g4, to force black to choose to push or defend? If 50...c4, 51. bxc4, bxc4 (...b4, 52. Kd4), 52. Kd4, and black seems lost. If after 50, g4, Ke6, 51. f5+, gxf5+, gx5+, white either queens the f-pawn or cleans up on the q-side and promotes there.|
|Jun-17-09|| ||WhiteRook48: right, 55. g6 was better|
|Sep-21-09|| ||kingfu: This was an exception to the rule. The rule: if you were in an endgame with a knight against Fischer's bishop, you lose. Fischer had a win in this game also.|
|Aug-27-10|| ||asiduodiego: <When you recall the Fischerīs career and quote games from 1958-1960 it seems not so fair> Cheap excuses. Fischer at 1959 had already won the U.S. Championship in earlier years, so the excuse of "he was soooo young", I find it laughable. He just miscalculated: every great player does that from time to time.|
|Oct-05-10|| ||dTal: Those who think Fischer was a poor endgame player should either play through a games collection of his, or read a book such as "How Fischer Plays Chess" by David Levy. He was a superlative endgame player. If anything, he wasn't comfortable in the crazy tactics favoured by somebody like Tal, as he liked to play without giving his opponents any sort of chance, and have everything under control.|
|Aug-18-11|| ||Tigranny: Any reason why Fischer didn't play 54.g6?|
|Aug-18-11|| ||Benzol: <Tigranny> <Any reason why Fischer didn't play 54.g6?>|
56.g6 b2 57.g7 b1=Q+ 58.Kf6 Qb8 59.Kf7 Kxc5 60.g8=Q Qxg8+ and Black will win with the passed a-pawn.
|Aug-19-11|| ||Tigranny: Thank you Benzol.|
|Nov-28-11|| ||OBIT: Yes, this is definitely a shocking blunder, even if Fischer was only 16 at the time. He definitely got his payback the following year, however, with two crushing victories over Letelier. Letelier vs Fischer, 1960 came at the 1960 installment of this tournament, and Letelier vs Fischer, 1960 is his famous queen sacrifice game.|
|Nov-28-11|| ||FSR: As I recall, Mednis in his book on Fischer's losses called 55.c5?? the worst blunder of Fischer's career. Obviously Fischer failed to notice that Black's b-pawn queened with check.|
|Nov-28-11|| ||FSR: <OBIT> Fischer beat Letelier like a drum in the other three games they played: http://www.chessgames.com/perl/ches...|
|Jul-15-12|| ||master of defence: Whatīs wrong with 55.g6? After 55...b3 56.g7 b2 57.g8=Q b1=Q+ is at least a draw for white.|
|Jul-16-12|| ||perfidious: < master of defence: Whatīs wrong with 55.g6? >|
Nothing at all-Fischer miscalculated. Happens to the best of us.
