Jun-04-05  Knight13: Hey man. This game is played in 1989. At that time computers weren't strong enought to beat GMs.
Sep-27-05  Averageguy: Why not 18.dxc6 Bxa3 19.cxb7+ K moves 20. bxa8Q ? I know that 18.Bxc6+ wins, but I was just wondering.
Sep-27-05  stephenw: <Knight13> Not true about computers not defeating GMs. See Larsen vs Deep Thought, 1989
Sep-27-05  PhilFeeley: Interesting interview with Kasparov in the Harvard Business Review (Coutu, Diane L., April 1, 2005, Vol. 83, Issue 4, p. 49)
Mar-27-06  vesivialvy93: i think the best dedicate chess computers of today's can play as good as deep thought (tasc r30 or mephisto atlanta)
Jun-15-08  iccsumant: < Jaymthegenius: In youre profile you say "Kasperov is best of all time!, get over" I disagree, as Kasparov has lost to Karpov, Anand, Ivanchuck, and Kramink in the past. I think it would be better to say Kramnik, Polgar, Karpov, Leko, Svidler, Larsen, Kasparov, Anand, and Ivanchuck are the best of all time, and the fact that Kramnik is world champion but Kasparov is highest rated player proves how flawed the ELO system is.>

Hmmm...you seem like a genius...are you showing off that you just memorized a bunch of leading grandmaster names or a super genius trying to make a conclusion that Kasparov is not the strongest of all time?

  JointheArmy: What a beating.
Jul-04-11  SetNoEscapeOn: Chessmaster's introduction to this game:

<The World Champion was invited to New York to face off with the world's leading main-frame computer program in a two-game exhibition at the Marshall Chess Club. The first game was a typical grandmaster crush, as Deep Thought was tied down to defense of the King pawn. In this, the second game, Kasparov opens the game up tactically and shows how a hesitant computer can be hung out to dry.>

Jul-07-12  HeadCrunch: A brilliant work of art by Kasparov against a fumbling Computer.
Jul-07-12  kingfu: Black sacrificed his Queen for positional beauty. Chess Computer programs have come a long way since then.
Jul-07-12  RookFile: Well, the fumbling computer was probably 2500 FIDE. Kasparov just smashed it as he would any other GM that strength, but the rest of us would not have done as well against Deep Thought.
Jul-07-12  Jim Bartle: How would white win after 12...a6?
Dec-16-12  Conrad93: 2500 FIDE. Err... Wrong! Robert Byrne (a brilliant GM) said he had to play the best game in his last ten years in order to defeat Deep Thought.

<How would white win after 12...a6?> I wasn't able to find an immediate win either, but White probably continues in gambit style: 12...a6 13. Rg1 Nf6 14. Be2 Bxe2 (looks safest) 15. Kxe2. White has a big lead in development in exchange for a pawn and a shattered kingside.
Jun-14-14  Shams: The two games of this mini-match are the "we'll always have Paris" of man vs machine play.

Strange comment given that Deep Thought's king pawn left the board on move 4 in that game:

  Zhbugnoimt: I love reading over past comments from years like 2004, where people still thought people could always get engines. The engines have progressed more than us humans in the past 11 years! More correctly, though, the programmers are progressing faster than the chess players.
May-31-17  Xonatron: Zhbugnoimt, I agree. I love these comments now that years have past by!
May-31-17  Xonatron: Stockfish 8 (after 6m20s) finally shows mate in 43 in the final position. It continues to narrow it down. After 9m40s it shows mate in 23. All with 37... Rc5. In years to come, it will be interesting to compare this analysis.
May-31-17  Xonatron: By helping it with moves, I got Stockfish 8 to solve mate in 22 at the end of this game, with 37... Rc2+.

Jun-04-21  macer75: lol... computers are so bad compared to humans
Sep-13-21  rwbean: Stockfish 14 after about 2 hours can't see better than mate in 21 ... 37. ♕d7 ♖c2+ 38. ♔d3 ♖b2 39. a6 ♖b3+ 40. ♔c2 ♖f3 41. a7 ... pesky checks and mate on move 57.

The computer annotation on this page doesn't give 9... ♘e5? a question mark ... it needs to run longer - it's about two pawns worse than 9...e5. It does point out that 12. ♕xc4 is better.

Jan-26-23  rwbean: Oops, left it a bit longer and Stockfish agrees, mate in 19. After 8,900 seconds, here's three ways it could happen.
