Kibitzer's Corner
Aug-13-03  ksadler: This game is annotated at for those who are interested.
Jul-28-04  chess4games: Interesting game.
Aug-21-06  I3illieJoe: This game should be game of the day...
May-04-07  iccsumant: Hey, do you want to know the history of this deep blue-Kasparov game? Check my blog for the great videos about the deep blue-Kasparov game. I guarantee that you would love it. Here is the link: http://www.chess-malaysia.blogspot....
Aug-05-09  Kinghunt: So what I want to know is if Kasparov ever had a win and made a slight inaccuracy or if he was just really close to winning but Deep Blue defended well. Any thoughts?
Aug-23-09  WhiteRook48: black can do a perpetual but if white is not careful the win can turn into a loss
Aug-23-11  SeanBurdine: This game cost Kasparov the match. He had to play Game 6 the very next day -- not a single day of rest in between -- and was psychologically devastated by seeing a seemingly certain win turn into a draw. Thus, the crushing 19-move defeat and the passing of the title of World's Chess Champion to a computer, an honor humans have never been able to wrest back since.
Jul-16-12  nitsud33: why not 50.Re2? any prob with this
Jul-08-13  yefri: hi nitsud33. After 50.Re2: 50..Rd1+. Then 51. Ka2 Ra1+ 52. Kb2 c3+ 53. Kc2 Rc1++ Mate. If b) 51. Kb2 or c) 51. Kc2 will not help using the same black move (c3 and Rook control row 1)
Jul-14-16  saintdufus: <the passing of the title of World's Chess Champion to a computer>

Actually that didn't happen, as this was only an exhibition match, not a title match.

However, this match did peremptorily prove that computers are stronger than humans at chess, which may have been what you meant.

Jun-04-17  Xonatron: 44. Rg7+ is coming in at +2.80 for Kasparov on Stockfish 8 at depth 39/91+ (after 8m:10s):
Dec-09-18  jdoucette: It appears to be a draw at the end of the game (score 0.00), backing up to the first 'mistake' = white's move 44, as @Xonatron pointed out:

Stockfish 10, 8-core, 8 GB RAM, 6-pc EGTB, 19 hours, depth 58 (extension 86+), 879,000,000,000 positions, score +11.12, move: 44.Rg7+

PV: 44.Rg7+ Kd6 45.g6 Nxb3+ 46.Kd1 c4 47.Rg8 c3 48.Rc8 Ra1+ 49.Ke2 Nd4+ 50.Ke3 Nf5+ 51.Kf4 Nd4 52.g7 Ne6+ 53.Ke3 Nxg7 54.Nxg7 Rc1 55.Kd3 Rd1+ 56.Kc2 Rg1 57.Nf5+ Ke6 58.Rc5 Re1 59.Kd3 Ra1 60.Ke4 Re1+ 61.Kf4 Rb1 62.g4 Rf1+ 63.Kg5 Rc1 64.Rc8 b6 65.Kf4 Rf1+ 66.Ke4 Rc1 67.Rc6+ Kd7 68.Rc4 Rc2 69.Kf4 Rc1 70.Kg5 c2 71.Nd4 Rg1 72.Rxc2 Kd6 73.Nf5+ Kd5 74.Rc3 Ra1 75.Kf4 Ra4+ 76.Kf3 Ke5 77.Re3+ Kf6 78.Re4 Ra2 79.Rd4 Ke5 80.Rd3 Ra1 81.Ne3 Rb1 82.Rd5+ Kf6 83.Rf5+ Ke7 84.g5 Rb3 85.Ke4 Rb4+ 86.Ke5 Ke8 87.Nd5 Rb1 88.g6 Kd7 89.Rf7+ Kd8 90.Rf8+ Kd7

Dec-09-18  jdoucette: Continuing backwards:. Black's 43...Nd2 was the mistake that allows the 44.Rg7+! winning move. Looks like 43...Rg2 draws.
Dec-10-18  Granny O Doul: I'd forgotten how interesting a game this was. And now I'm going to forget again.
