 | | kevin86: jw,do computers pick the gotd-if so do they ever pick a game they lose? lol Watch for DEEP BLUE 6 (aka deep six) that not only defeats the opponent,he kills him as well. OUCH! |
|
| Aug-25-10 | | lzromeu: <SugarDom: You know what is actually amazing about this game? It shows that Kasparov is really deep> Kas was exausted, psychologically beaten, and He actually knew that this game would take some hours more, and this was only the game 2 . But He believed that resigned in a drawing position, until now. |

 | | David2009: It is not widely known that this game has continued as a consultation match: Deep Blue and human allies vs Kasparov and Crafty End Game Trainer. Unfortunately both Deep Blue and Kasparov had to leave the scene after completing their 45th move: Kasparov, very generously, allowed his consultation partner (Crafty EGT) to over-ride his first choice (45...resigns) since, as is well known, no matter how desperate the position Crafty EGT always prefers being checkmated to resigning. Crafty decided to answer 45 Ra6

with 45...Qxc6. Does anyone know how to win as White? Crafty link: http://www.chessvideos.tv/endgame-t... |

| Aug-25-10 | | rapidcitychess: Today's game is like a boxing match, a long match with a slow buildup of "hits". Deep blue throws a left jab, just to soften him up with 19.a4, and just prances around his opponent for 3 moves in order to land another light jab with 22.b4. He starts pulling his arm back with 24.Ra3 and 25.Rca1 but then feints to the right with 26.f4 Black plays it safe and waits with a counter attack but Blue pushes the feint with a light hook to the chest. They wait around for a couple moves and Blue starts coming in with 30.Bb6, then keeps on pulling the rope in with 37.Be4 until he reaches his full swing with 46.Ra6 and Garry doesn't swing for the chin with 36...Qe3 ( This just might be my imagination but I think that's the move that draws.) And he throws in the towel. |
|
| Aug-25-10 | | SugarDom: The conclusion is:
It's not a drawn position after the last move... |
|
| Aug-25-10 | | FISCHERboy: Nice one, leading to a draw. f4-f5, Nf4 after black take pawn d4 the feeling is "is in danger, but it seems to have enough defence in any lines. |
|
| Aug-25-10 | | FISCHERboy: It's something to ponder about. Takes a lot of time to evaluate this. Gary might have shut the computer down himself.

| | OhioChessFan: Again, to all those who point to stronger engines finding Be4 easily. If it's such a good move, why in the world did it take DB so long to find it? Why did it go into panic mode? Surely Qb6 is pretty good. |

Thanks to you, I now agree that the game was indeed a draw in the final position. Your line on April 3 convinced me: 45. ... Qe3 46. Qxd6 Re8 47. Qd7+ Re7 48. Qc6 Qxe4 49. d6 Qd3+ 50. Kg1 Re8 51.

| Jun-09-11 | | DrMAL: In game 1 Deep Blue played with a materialistic style similar to all other games GK ever saw a computer play. In game 2, its style was completely different, baffling GK and causing him to be increasingly exhausted as the game wore on. In the film "Game Over" he elaborated on this and stated clearly he thought at the time he was simply going to lose his bishop on d6 so he resigned. While computers are prone to power outages humans are also prone to exhaustion. As GK said, he was exhausted and he blundered in not seeing his simple out, that's all there was to it. I put this position on Rybka 4.1 and after an hour at d=24 the score is +0.94 then I tried 45.Qd7+ instead only to find the score +2.10 at d=24 apparently a much better move than was played! Both GK and DB made inaccuracies throughout the game (as would Rybka or anything/anyone else) so who knows how it would have turned out? Analysis is useful for learning but it cannot predict what a player or computer may do. Since the consensus afterwards was that the position was a draw if GK played on it likely would have been agreed to. But he didn't he resigned. |

| Dec-01-11 | | Atking: Looks to me draw even in this last line. 45...Qe3 46.Qxd6 Re8 47.Qd7+ Re7 48.Qc6 Qxe4 49.d6 Qxf5+ 50.Kg1 Rd7 51.Qxb5 Qe6 52.Qc5 Kg6 53.Rc6(Or b5) e4! 54.b5 (Or Rc6 Else 54.Qxc4 QxQ 55.RxQ Kf5 56.Rc6 Ke6 with g6-f5 White King can't help its own pawns on Queen side It's draw) 54...e3 55.Qxc4 Qe5! 56.Rc5 (56.Qg4+ Kh7 57.QxR? e2 Or 56.Qe2 f5 57.c4 Kh7 58.c5 Ra7 59.Ra6 Rb7! =) 56..Qxd6 57.Qe4+ Kf7 58.Qxe3 Qd1+ 59.Kh2 Qd6+ 60.g3 Re7 Black initiative is enough to draw. For if 61.Qd4 Re2+ 62.Kh1 QxQ 63.cxQ Rb2 64.Rc7+ Kg6 65.Rb7 Kf5! 66.Rxg7 Ke4 67.Rg6 f5 68.b6 Rb1+ ~ even with a pawn on h4 (Instead h3) the draw is there. Kh2 Rb2+ Kh3 Rb1 eccetera. What will says IBM team if this ending is draw... But if a winning line is some where (Which I doubt a lot) then it was out the border line of Deep Blue calculation. |

| | OhioChessFan: I am now doubting <48...Qxe4> as best for Black in the infamous perpetual line. I have 45...Qe3 46. Qxd6 Re8 47. Qd7+ Re7 48. Qc6 <Qf4+> I haven't seen any other analysis of it. Most of the following seems pretty forced: 49. Bf3 Qc1+ 50. Kf2 Qd2+ 51. Kg1 Qc1+ 52. Kh2 Qf4+ 53. Kh1 Qc1+ 54. Bd1 Qxd1+ 55. Kh2 Qd2 56. d6 I think now Black's best is
56...Re8 57. Ra1 Kf8

Back from a long hiatus, I want to make a PGN file with many different lines. I'm pretty sure the game is drawn, at this point, though. But it was just a lucky guess by the commentators; this line wasn't analyzed. |
|
| Feb-07-13 | | RookFile: There is some resemblance here to the way Fischer loaded up on the a file against Spassky in 1992 to win that Ruy Lopez. Kasparov at the time criticized that and said white should have played f4 instead, but that criticism quietly went away. Then, the computer does the same thing to Kasparov. |
