Sep-27-06  whatthefat: While it wouldn't be the stupidest thing Fischer's said, it looks to have been a 2004 April Fools joke. A couple of sites quote the 'breaking news': http://www.net-chess.com/phpBB2/vie... www.chessdryad.com/articles/ccj/pdf/apr_04.pdf
Sep-27-06  olelz: thanks <whatthe>. the article is really amusing. here are some quotes from Fischer found on http://chatna.com/author/fischerbob...

You can only get good at chess if you love the game. Bobby Fischer

I like the moment when I break a man's ego. Bobby Fischer

Chess is life. Bobby Fischer

Chess is a matter of delicate judgement, knowing when to punch and how to duck. Bobby Fischer

Is it against the law to kill a reporter? Bobby Fischer

I don't believe in psychology. I believe in good moves. Bobby Fischer

Chess is war over the board. The object is to crush the opponent's mind. Bobby Fischer

A little agressive, don't you think?

Sep-27-06  Tomlinsky: They all strike me as humorous personally.
Nov-01-06  Tenderfoot: It's those two consecutive knight advances that seem to really do Kasparov in. After 13. Nb5 and 14. Ne5, Deep Blue has a great position on Kasparov, I think. They allow for Deep Blue to wreak havoc on Kasparov's pawn structure. Pretty nice positional thinking from a computer.

  Chessical: <Shakur> If <35...Qxf7> 36.Qd8+ and then Black blocks the check with <36...Re8>, White then wins with <37.Qxd4+!> Kg8 38.Rxf7 Kxf7 39.Qxf2.
Jan-17-07  ettoremaceio: People, but if <35...Qxf7> 36.Qd8+ and then Black blocks the check with <36...Re8>,<37.Qxd4+!> Kg8 38.Rxf7 Rh1++ ??? It´s right?
Jul-13-07  Morphyisgod: wat bout 35. Nf7+ Qxf7 36. Qd8+ Qg8
Jul-13-07  Pi Guy: <Morphyisgod: wat bout 35. Nf7+ Qxf7 36. Qd8+ Qg8>

37. Qd4+ Qg7 38. Qxg7#

Kasparov could survive an extra turn by blocking the queen with 38. Re5, but he can't prevent the checkmate.

Jul-15-07  Morphyisgod: thanks i c
Aug-30-07  KasparovFan123: Kasparov and deep blue played essentially the same opening as they did in a previous match and arrived at the same position after 12 moves. Deep blue chose Ne5 and the game ended in a draw however in this case it played Nb5 before Ne5 and that gave it a huge positional advantage.

It was really surprising to see Kasparov's position after move 24. I do not think that I have seen any of his games with such a horrible pawn structure. The black pawns will just picked off easily. Kasparov was not close to winning this game at all. His moves at the end of the game was merely a desperate attempt to get counter play by harassing the white king. He probably knew that he lost the game well before that.

Fisher's comment is quite outrageous but not surprising from a man who still considers himself the World Champion. A very talented player, a very huge ego, amazing amount of self belief on a chess board.

Sep-21-07  neverfallen: One question guys, why did kasparov resign? what is gonna happen if they play on!

  SwitchingQuylthulg: <neverfallen> 37...Kg6 38.Qg8+ Kf5 39.Nxf3 threatening 40.Qd5+ Kg6 41.Qh5# as well as the obvious 40.Nxe1. If 39...Rh1+ 40.Kg2 Ke4 41.Rf7 and Black loses yet more material; all of his pieces are en prise and there are many mating nets to look out for (indeed my friend the computer suggests just giving up his queen with 41...Qxf3)...
Nov-26-07  patzer2: Kasparov's first significant mistake, and most likely the losing move in this game, was 27. d4? Instead, 27... f4! 28. Kh2 Qg5 29. Rg1 f6 = holds the position.

By the time Kasparov played 34...Nxf2 to threaten mate-in-one, he was already lost. Still, the attacking defensive move 35. Nxf7+!! by Deep Blue is esthetically pleasing -- even if it is the product of brute force calculation.

A break-out of Deep Blue's win with 35. Nxf7+!! follows:

<35. Nxf7+!! Kg7 36. Ng5+>

(36. Ne5+ Kh6 37. Nxf3 Re2 38. Rc6 Ne4+ 39. Kg1 )

<36... Kh6 37. Rxh7+ 1-0>

Play might have continued with the possibility 37...Kg6 38. Qg8+ Kf5 (38... Qg7 39. Rxg7+ Kf5 40. Qf7+ Ke5 41. Qe6#) 39. Nxf3 Rh1+ 40. Kg2 Ke4 41. Rf7 1-0

Yeah, I agree. He wasn't given a whiff of initative in the game. Apparently the commentators though 13..Qe7?! was of mixed value. The two reasonable alternatives were

13...Qb8 14. Ne5 Bxe2 15. Qxe2 0-0 16. Bg5 Nxe5 1. dxe5 Nd5

13...Qd5 (following the 3rd game of the match)

--analysis done with several other club members a couple of nights ago.

Anyways, 23 d5! was a nice move, breaking up the Black's pawn structure a little more.

  OhioChessFan: Fritz thinks 27...d4 was a .9 pawn blunder, and even had Black with a small advantage with f4.
Jun-05-08  DarthStapler: This is probably one of the most famous chess games of all time
Jun-05-08  kevin86: Machine beat man-A result bad enough to break one's heart. (Read the John Henry legend to get the true meaning of that pun).
Jun-05-08  Chessmensch: This is reminiscent in some ways of what (much weaker) chess programs do to me. They jump on every weakness relentlessly and never give the opponent an opportunity to develop a reasonable position or plan. But, while that happens to me, it shouldn't have to Kasparov.
Jun-05-08  Udit Narayan: Really a complicated game...
Jun-05-08  Marmot PFL: Nobody would play like this against a top computer today, but it was games like this that made folks realize how futile it was.

As for Fischer's alleged claims, I read an interview with him from around 1970 in which he agreed with Botvinnik - that computers would be so strong someday thst they would at least draw with GMs. This was back when computers played like garbage.

Jun-05-08  Eyal: From the transcript of the live commentary to game 1 of the 1997 re-match:

<MIKE VALVO: In open positions they have a thing called move extensions. Which means, if I capture something, I'm not going to stop analyzing there. I'm going to see what happens. If he can recapture, then I will exhaust all capture situations down to their end, which is something I'm not going to bother doing in some blocked positions, not even have the opportunity of doing. In tactical situations that could be a big edge to the computer. Tactical situations in fact are to a computer's advantage.

MAURICE ASHLEY: Right, we saw that in game one last year where Kasparov --

MR. SEIRAWAN: Got massacred.

MAURICE ASHLEY: Got crushed. He sacrificed a pawn thinking that he had a great king-side attack, but the computer had calculated it to the finish, and admittedly humans would not have taken that pawn, unless you were drunk or something, but in that situation the computer had worked everything out to Kasparov's being crushed, instead of itself being mated. And so Garry ended up losing that game, and he learned his lesson well and avoided sharp, open, tactical positions from that moment on.

MIKE VALVO: Can I tell you something from last year's game that wasn't well known?

MAURICE ASHLEY: Please.

MIKE VALVO: Garry left his score sheet behind. That's the only game he forgot his score sheet. He was pretty upset.

MR. SEIRAWAN: You're talking about the game he lost in game one?

MIKE VALVO: The game he lost, yeah.

MR. SEIRAWAN: Probably didn't want to keep it.> (http://www.research.ibm.com/deepblu...)

I also remember reading an interview with someone from Kasparov's team, who said that they were quite nervous before this game, because they really didn't know how strong Deep Blue is going to be. But after the game was over and analyzed, they actually became optimistic about Garry's chances despite the loss, because they've noticed several inaccuracies committed by the computer and came to the conclusion that it can be handled with the right strategy (indeed, DB scored only 1 point in the next 5 games of this match).

Jun-05-08  drpoundsign: who says computers can't sac?? Gary needed to remember king safety. The machine did not even need an endgame to win.
Jun-05-08  Jim Bartle: "The machine did not even need an endgame to win."

But it had to calculate to mate, with check every move, as black was threatening mate in one starting on move 34.

Jun-05-08  lau7aro: Would somebody be kind and explain me why Deep Blue avoided 18. Ng4? It seemed a good post and reinforced attack over Knight f6.
Jun-05-08  Shams: <lau7aro>
because of 18...Nxd4
