Kibitzer's Corner
Jul-31-03  erikcu: I am a lowly 1400 player. I am wondering where Kasparov's blunder is. Moves 26. and 29 seem to allow Deep Thought to advance his pawns, but I wonder if the game was lost before then? Kasparov's Queen and King movement in the mid/end game looks like a cornered player.
Jul-31-03  Benjamin Lau: Erikcu, the reason you can't find Kasparov's blunder isn't because you're rated 1400. It's because Kasparov won.
Aug-01-03  stef21: nice strategic exploitation of the bad bishop good night concept
Aug-01-03  caseyclyde: BenjaminLau & Ericu, I have to thank you for giving me the biggest laugh of my morning!
Aug-01-03  erikcu: Opps, I thought Kasparov was white! That must explain my rating, been moving my opponents pieces all these games; dang. I see what you are saying stef21, Kasaprov could see that the knight would be useful well before it was comming into play. So while Deep Thought was searching deeply it could not recognize the long term threat of that knight.
Jul-29-04  wallnuts23: erikcu, excellent anyalysis! Wow, I can't believe you can read the thoughts of Deep thought, I'm impressed!
Jul-29-04  Keshishian: Wallnut, give Erikcu a break. We were all 1400 at some point, and he's putting an effort forth.
Mar-11-06  Ludamad: Was wallnut being sarcastic? It didn't seem so to me.
Sep-19-07  neverfallen: Keshishian is right we should give erikcu a break but its interesting what is his rating now.
Oct-15-07  aazqua: Kasparov is white. He happened to be playing black on this occasion. I can't think of anything less interesting than Ericu's rating.
Jun-09-09  Slurpeeman: Wallnut is a moron. Erikcu is right about Deep Thought. I'd like to see Walnut play Deep Thought and see if he had much energy for sarcasm
Sep-18-09  DrCurmudgeon: This game was featured on the PBS series Nova in the episode, The Chip And The Chessmaster. It concluded with Kasparov being asked, "How will you feel if you lose to a computer?" He replied, "Game or match?"

The future was set right there.

Mar-06-12  screwdriver: I thought I'd see someone in the comment section with a modern day chess program tell us all what was wrong with Deep Blue's play. Houdini, Rybka, or Fritz probably would've played the game differently.
Dec-18-15  thegoodanarchist: Yes, Kasparov won this game. But Deep Thought later got revenge, defeating Kasparov in a game of Hūsker Dū?.
May-31-17  Xonatron: Stockfish 8 is showing mate in 27 at end position with 53. Rxe2.
May-31-17  Xonatron: Stockfish 8 shows Kasparov had a mate in 16 with 46... Nxe3 47. fxe3 Rxe3 (all forced) and then it seems black has 3 pieces attacking e2 and e3 and white only has two defenders, meaning it will lose a rook, and then somehow get mated. Makes sense?
May-31-17  Xonatron: Stockfish 8 shows Kasparov had a mate in 26 with 45... Kf6! (His previous move of 44... g3 is also this same mate.) It follows: 46. fxg3 Nxe3 47. Rxe3 Rxe3 48. Qxf3 Rxf3 (all forced) and then black is up a rook and mate follows in 22 more moves.
Sep-15-21  rwbean: 37. ♖b2 is -0.64 (SF14, 57 ply)

37... ♘c4 is -4.01 (SF14, 40 ply)

so it's like one move was enough to lose. Bad move!

So far, I've looked at "Kasparov v Deeper Blue" (Daniel King, 1997 - p.27), "Kasparov vs Deep Blue" (Newborn, 1997) "Behind Deep Blue" (Hsu, 2002) ... blames bad play on a bug on pp113-114 ... don't they always :-) ... nobody seems to notice this move was terrible. Computers are much better these days!
