| Dec-16-11 | | rilkefan: Sort of glad to see b5 is winning - I didn't give up on it so much as get distracted by a shiny object. |
 |

 | | Morten: I see that Bobby himself didn't spot the solution on the first try (after 44.-, Kc8). That makes me feel just a little bit better. |
|
Dec-16-11
 | | sevenseaman: Dead equal. Aggressive White is almost entirely fighting in enemy territory. That means he is confident of a win. I have now wrestled with the problem for over an hour. Very rare for me; whats more I am still blank. I've tried B+ to push the Black K west. I've tried Re6, the K comes closer to his B. I have resisted immense temptation to chuck it and look up. That hurts and brings down ego many a notch. I have been doing problems that looked much more complicated. The only thing that has held me in bondage is that it being a puzzle there <is> a solution. Madman Fischer, what the dickens did you do? Only one hare-brained idea still remains (but hardly appeals). How about Bg8? The Black R must maintain rank; it can do so only at c7. Now what. If I B-check now, Black will insert his B. What do I have then? I cannot think of any forward step. I take, he takes. No sir, hands up. I need Black to make a mistake and take his K to b8 so that I bring my R to d6. Based on a wrong move from the opponent, that is hardly a solution. This is first failure in a long time that I will attribute to lack of ability alone. No excuses. |
|
Dec-16-11
| | sevenseaman: No. I have not understood Fischer's solution even now. I can understand he stands better and will ultimately win with Ps. That way I had considered b5. Its a good way to win, but pedestrian. I was looking for something spectacular. I do not see why Black K should withdraw to b8. |
|
| Dec-16-11 | | gofer: The white king is god. He is controlling everthing that black is trying to do. White could try <48 Bg8 Rc7 49 Be6+ Kb8 (Kd8 Rd6+ exchanges into a win) 50 Rd6> at which point
the black king is stranded and Be8 is about to be taken so moves like Rc3 taking Pg3 are probably
very flawed. Any bishop move leads to an exchange or loss of Pg6 and Pf5. I also looked at the other tactic;
<48 Bxb7+ Rxb7 49 Rxb7 Kxb7 50 Ke7 Bc6 51 Kf7> now this seems a little extreme! So I am going to go for my first option! Time to check... |

 | | morfishine: THREE STAGE THOUGHT PROCESS:
(1) I've seen this game so will have to bow out
(2) I actually don't recall this game so will have to solve it (3) Not only do I not recall it, I'm unable to find Fischer's marvelous idea And thats how I got to <48.Re6> |
|
| Dec-16-11 | | realbrob: <sevenseaman: I do not see why Black K should withdraw to b8> Well, if 49..Kd8 it's pretty obvious that White trades down both pieces and wins easily. Maybe trickier is 49..Bd7, but White can simply play 50.Kxg6. |
|
| Dec-16-11 | | Prosperus: Can somebody tell me what was yesterday's game, please! |
|
| Dec-16-11 | | gofer: <sevenseaman>, <realbrob> means something like this... 49 ... Kd8
50 Rd6+ Bd7
51 Rxd7+ Rxd7
52 Kxd7 Kxg6
53 Ke6 Kg5
click for larger viewThe white king delays taking Ph5 for a couple of moves (and in fact probably never does!) and instead takes
Pf5 gaining control of the centre allowing Pf5 to be promoted to the 7th at which point
black can try to block promotion, but cannot because there is no stalemate instead black is forced
to play 1 ... b6 2 axb6 a5 3 b7 any move 4 b8=Q# |

| | sevenseaman: <realbrob, gofer> What I meant was 49...Bd7 and not Kb8. Of course the game will go 50. Bxd7 Rxd7 and White gets on with mopping up K side Ps. I had the solution but was not impressed that the win was ultimately only a grind. Thanks. |

| Dec-16-11 | | Prosperus: @Phoni Benoni Many thank! |

Dec-16-11
 | | Patriot: I first looked at Bxb7+ and Re6. After 48.Re6 I thought 48...Rf7+ but obviously I didn't look at that line very well. 48.Bxb7+ doesnt seem to work either since 48...Rxb7 49.Rxb7 Kxb7 50.Ke7 Bb5 51.Kf7 Be2 52.Kxg6 Bg4  . I don't have any confidence in 49.Rxa6 Rxb4 either. The only move that seems to gain positive traction is 48.Bg8. This simple threat took too long for me to see, proving that my candidate move selection is not very efficient. 48...Rc7 is the only candidate since 48...Rd7 49.Be6 wins. So... 48.Bg8 Rc7 49.Be6+ Kb8 (49...Kd8 50.Rd6+ Bd7 51.Rxd7+ Rxd7 52.Bxd7 Kxd7 53.Kxg6  ) 50.Rd6 (threatening to win the bishop) . The bishop will now have to move, giving away the g6-pawn. |

chancho: <chessgames.com> This game was played April 8, 1959 in Mar Del Plata, Argentina and I have the gamescore in The Complete Games Of Bobby Fischer page 169, game #314. The name of the player in the above game is not Julio, but Jacobo. Please correct this error. <<>> >> Good catch!!!
I love it when users/readers find and make corrections. Personally, I want everything to be 100% accurate. Possibly the only change I would make - is when a game is not listed in CB - there could be a source listed ... |

 | | chrisowen: Fischers instincts told him where the ghoulies lay it new arrival king lsb rooks all hunker down in black siege the penetrating mind will investigate bishop in dead duck Julio wriggle only it is for in piece again trouble d6 Robert in low rich vein hustle man black square kb8 rd6 1-0. |
|
| Dec-16-11 | | cydmd: Note that Fischer reached the same position twice (on moves 45 and 48). And only at the second time he devised the winning plan. I did see both moves but that game shows some choices are tried out OTB. |
|
| Dec-16-11 | | pawninthemachine: Hello all, first posting here. Correct me if I'm wrong but didn't Fischer earlier miss a winning simplification with 39. Rf7+ ? 39...Rxf7 40. Bxf7 g5 41. hxg5 and so on. |
|
| Dec-16-11 | | gofer: <sevenseaman> For us meer mortals it is a "grind" as we are probably going to be forced to play it out to its bitter end. But for Fischer, it was a <Done Deal, Game Over, The Fat Lady Is Singing and Elvis has definitely left the building!>. So the "grind" simply doesn't exist... |
|
| Dec-16-11 | | jackpawn: In a five minutes game I would definitely play 48. Re6. Obviously Fischer's solution is far better. |
|
| Dec-16-11 | | TheoNov: POTD - TN 1-0 :-(
A very nice problem. Tried the faulty 48.Bxb7 sac, then saw 48.Bg8 Rc7 49. Be6+ but missed the implications of this.But those that didn't get this one, don't feel bad -- even Fischer missed things in this game. Like, he could have won earlier after 37...Bc6 
click for larger viewwith the somewhat obvious 38.Rxg6 (instead of the text move 38.g3) where: a) 38... h5 39. Bxf5
b) 38... Bd7 39. Ke5 h5 40.Kxf5
c) 38... Bxg2 39. Rxh6 (39.Bxf5 and 39.Ke5 also win) Bh3 40. h5 Bg4 41. Ke5 and the h-pawn is unstoppable. Why didn't Fischer play this? |
|
Dec-16-11
 | | kevin86: I was looking at the sacrifice/novotny theme at f7. But it failed. Fischer found the proper finesse with the bishop to win an end game more complicated than it seems. |
|
Dec-16-11
| | Patriot: <gofer> <The white king delays taking Ph5 for a couple of moves (and in fact probably never does!)...> I think white can take on h5 right away:
54.Kxh5 Kf6 (54...Kf7 55.Kg5 Ke6 56.Kg6 ) 55.Kh6 Kf7 56.Kg5 Ke6 57.Kg6 Also he could play 54.Kxh5 Kf6 55.g5 fxg5 56.Kxg5 . |
|
Dec-16-11
| | JimmyRockHound: I spotted Bg8 straight away as putting pressure on the rook. I knew it had to move to c7 but didn't pursue it any further because my brain struggles to think that far ahead and I don't use a board or silicon on principle. Do I get a point? |

| Dec-16-11 | | LIFE Master AJ: Brief thoughts.
POTD / Thursday; Dec. 16th. 2011
click for larger view White to move, 48. '?'
Kotov said you have to examine ALL checks, captures, etc. Forcing moves take high priority. For me, the magic number - for most positions - is to find three CANDIDATE moves. White is clearly much better, all of his pieces stand on much more active squares than his opponents ... but can this be turned into a viable (winnable) advantage? I quickly looked at 48.b5, and 48.Be6+, but quickly dismissed these. (Whether this was 100% correct or not, is another matter.) Now my three main choices are:
#1.) 48. Sack/capture on b7 ... by the WR or the WB. #2.) 48.Re6, harassing the Black Bishop on e8.
#3.) 48.Bg8, hitting the BR on h7, which upon close inspection, does not have a lot of good flight squares to go to. *****
Initially, I thought that #1 was the most promising, however, several users have pointed out that it fails ... as the Black Bishop dances over to g4 and stops White cold. Then two looked really good ... but the more I analyzed, the more obscure things became. Of course, it turned out #3. was best ... but FAR from being easy, I saw one line where White took on g6, but Black's Rook got active and captured a few Pawns ... [ 48.Bg8! Rc7T; 49.Be6+ Kb8; 50.Rd6 Ka7;
51.Rd8 Bb5; 52.Rc8! Rxc8; 53.Bxc8 Kb8;
54.Be6 Bd3; 55.Kxg6 Be2; 56.Kxf5 b6;
57.Kg5 bxa5; 58.f5! Kc7; 59.f6 Kd6;
60.Kg6! Bd3+; 61.Kg7 Kxe6; 62.f7 axb4;
63.f8Q, (Fritz 12) ]
