|Jan-25-08|| ||ruzon: <Infohunter: <zooter: ...can somebody explain to me the continuation after
46...Ra2+ 47.Nb2 please>
I came up with this: 47...Nxc3 48. Kxc3, Bxb4+ 49. Kc2, c3. If now 50. Be1 then 50...Rxb2+ 51. Rxb2, cxb2 52. Bxb4+, Kxb4 53. Kxb2, b5!>
I think 52...Ka2 forces the game to end more quickly.
|Jan-25-08|| ||mworld: im proud of myself, i actually analyzed the line where the knight moves to b2 to block Ra2+ and got to that end game analysis before looking at whites played Rb2.|
|Jan-25-08|| ||wals: first glance, what move intuitively springs to mind
Correct BUT I messed up badly with the following moves.
|Jan-25-08|| ||hkfr: missed everything. And without others posting I have had to work hard to understand what happen after seen the game.|
The only thing I looked into was 46 ..Rxb1 47 Kxb1 Nxc3 48 Nxc3 Bxb4
thinking that might black could win here due to that white bishop still seems to be passive. So far out!

ZOMG I GOT THIS ONE IN 8.3114 seconds!!!! That means I've solved 93 puzzles in a row.. man I'm on a roll, and I thought I was just average, but apparently, I'm pretty good, like, I'm a Super GM or something.|
No one cares people...
|Jan-25-08|| ||littlefermat: I saw this puzzle in the morning, and let it sit in the back of my head all day. I finally got it this evening with Ra2+ |
The only way I got this was by grinding out the calculations--I had absolutely zero intuition of what the right moves would be. Quite literally I wrote out the calculations a post-it note. I can't believe people would find this stuff (or any Sunday puzzle) OTB.
It's amazing that Fischer had the idea of inflitrating White's position around move 21, where the liquidation of material begins to take place.
Interestingly enough, Acevedo was the "code" that Nigel Short and Fischer communicated to one another during the alleged blitz games around 2003(can't remember the exact date).
|Jan-25-08|| ||DarthStapler: Saw the idea but missed the last move|
|Jan-25-08|| ||ex0duz: Kevin86, have you seen this game? Karpov vs Unzicker, 1974|
I'd say those knights and rooks are the most pathetic things i've ever seen in a closed pawn position..
I too had to read patzer2's post to fully understand the position.. pretty tough one for me today :(
|Jan-25-08|| ||johnlspouge: Friday (Difficult): Black to play and win
Material: even. White has the bad B and his entire position is constricted.
SPOILER WARNING: This is the mother of this week's second-best moves!!! I not giving myself any credit, it is probably not worth reading, and I really should learn when to give up. It was interesting, though...
Candidates (46...): Rxb1
[I dismissed Fischer's 46...Ra2 as completely ineffective.]
The move 46.Rxb1 seizes the opposition and permits the White K to penetrate further to intensify the pressure on Pc3.
46...Rxb1 47.Kxb1 Kb3 48.Be1
Candidates (48...): Bxb4, Nxc3, Na3, g5, h6
Let's sample the interesting sacrifice Bxb4 first, because it is most forcing, and because K-side P play can be sought at any time. Note that any line with an uncompensated exchange of Black B for White N is a win, because the White B is so bad.
48...Bxb4 49.cxb4 c3 50.Kc1
No immediate progress appears possible, but Black's position on move 48... can be improved, because White is so passive. White's Ne1 must stay put as long as Black's N threatens Pc3 and cannot stray far, and his B and K can at most shuttle Be1-d2-e1 and Kc1-b1-c1.
Black therefore tours his Nb5 with Nb5-c7-a8-b6-a4 and an intermediate b5. Because Black can burn tempi with his B, he can achieve an equivalent position (outside irrelevant K-side P moves), Black to move, with the Black Pb6 at b5 and the Black Na4, and with the White Kc1 and Be1 or with the White Kb1 and Bd2.
Start the move count when the position is achieved with Black to move:
1...Bxb4 2.cxb4 c3
Case 1: White pieces are Kb1 and Bd2. All pieces must be exchanged at c3 (else 3...c2), leaving White with a won K+P endgame.
Case 2: White pieces are Kc1 and Be1. The lines in Case 1 pertain, so only one viable defense remains.
All defenses fail.
4.Nd1 Nd3+ and 5...c2+ 6...c1=Q
4.Kb1 Nd3 5.Nxd3 dxe3 and after the exchange on d2 of 2Ps for B, Kxb4 and the game is won.
4.Bxc3 Kxc3 and White has a won K+N+P endgame.
The parity of the position of the White K and B makes the idea behind my line feel positively bizarre. Fischer probably found something more elegant. Time (at last!) to peek.
|Jan-25-08|| ||D4n: This is simple if you take it in small steps, you need to distance the king from the rook or knight, rook to Ra2+ then get the knight, and sacrifice it and go from there..|
|Jan-25-08|| ||xrt999: In the chessmaster database, there are some additional moves played:
49.Kc2 Rxd1 50.Kxd1 Kxb2 according to chessmaster
|Jan-25-08|| ||johnlspouge: <MostlyAverageJoe>, my lines for today's second-best move might (as always) be in error, but am I correct in assuming that a computer would have a tough time finding a win involving the lengthy N tour my post suggested?|
<dzechiel>, you think <you> are embarrassed?!? In future, I will remember that failure is always an option.
|Jan-26-08|| ||OBIT: Playing around with this position for an hour or so, I'm 99% convinced 46...Rxb1 47. Kxb1 Kb3 48. Be1 Na3+ 49. Kc1 Nc2 also wins, mainly because of the hideous lack of mobility for White's minor pieces. The quick wins come after (a) 50. Bf2 Nxb4! 51. cxb4 Bxb4, and White is helpless against ...c3 followed by ...c2, or (b) 50. Kd2 Nxb4! 51. cxb4 Bxb4+ 52. Ke2 53. Bxe1 Kxe1 54. c3, and again White is dead after ...c2.|
That leaves (c) 50. Bd2, in which case Black resorts to slow strangulation. The winning plan is to shift operations to the kingside by 50...g5! If White does not take the pawn, Black can continue with ...g4, followed by ...h5 and ...h4. If White does play 51. fxg5, then Bxg5 followed by ...h5 and ...h4. I figure, one of the following has to happen:
(1) The Black bishop gets to h4, when ...Ne1 followed by ...Nf3 puts White in zugzwang.
(2) The Black pawn on g3 becomes isolated or backward. In this case, the bishop wins the pawn and again gets to the h4-e1 diagonal.
(3) The White pawns get to h3 and g4, when ...Bh4! forces the promotion of one of these pawns.
Is there a defense for White?
|Jan-26-08|| ||OBIT: Adding to my previous comment, here is a sample continuation that I think is interesting. After 46...Rxb1 47. Kxb1 Kb3 48. Be1 Na3+ 49. Kc1 Nc2 50. Bd2 g5 51. fxg5 Bxg5 52. Kb1 h5 53. Kc1 h4 54. gxh4 Bxh4 55. Kb1 Ne1 56. Bxe1 Bxe1 57. Kc1, reaching the following position:
click for larger view
At first glance, it may appear that White's h-pawn is too dangerous to allow Black to pick off the c-pawn, but that is not the case: 57...Bxc3! 58. Nxc3 Kxc3 59. h4 f4! and wins the king and pawn endgame: (a) 60. h5 f3 61. Kd1 Kd3 62.Ke1 c3, or (b) 60. exf4 e3 61. Kd1 Kd3 62. h5 e2+ 63. Ke1 c3. In either line, Black wins by one tempo.
|Feb-11-11|| ||HeMateMe: Chessdotcom has an article on this game, how to make a plan to win a position like this; etc. Pretty clever. The ugly Knight that can't get into the game becomes undefendable. |
I had not played through this before; i thought at some point black would sac the Bishop for two pawns on the queen side and shove a pawn home, escorted by his King, after trading off the rooks.
|Feb-12-11|| ||newzild: The position after 47. Rb2 would make a nice Tuesday - Wednesday puzzle.|
Excellent endgame by Fischer, who made it look easy. The following article shows how a difficult the endgame really was:
|Feb-12-11|| ||BarcelonaFirenze: Yes, it seems Nigel Short asked his opponent (who was beating him all the time in internet blitz games) who was Norman Acevedo... The answer was "Siegen 1970". Therefore, Short claimed he had been playing Fischer. Fischer denied this later on.|
|Aug-10-12|| ||Garech: Great crush from Fischer!
|Aug-10-12|| ||ughaibu: Are you sure about that?
|Aug-10-12|| ||I play the Fred: Awesome!
|Aug-10-12|| ||ughaibu: Oi!
|Aug-10-12|| ||ughaibu: What an incredibly boring game.
|Aug-11-12|| ||perfidious: < jovack: <Here is a recurring theme frequently seen in the kibtiz's of these puzzles> ZOMG I GOT THIS ONE IN 8.3114 seconds!!!!

Recurring theme is an understatement.
As I failed to see this within five nanoseconds, my place in Kibitzer Hell awaits.
|Aug-11-12|| ||RookFile: White had a bad dark squared bishop and lost control of the a file. That's all Fischer needed to win.|
|Aug-11-12|| ||harrylime: Usual Fischer 'haters' all present and correct I see ! lol|
