May-16-05  WorldChampeen: Karpov wrote the book on the Caro Kann!
May-17-05  RookFile: Got me thinking.... I think Capablanca was the first great player to use it, but of course, he didn't write a book about it.
May-18-05  woodenbishop: Very impressive (though typical) end game by Karpov.
Mar-21-06  64 Squares: This game looks like a game of Deep Thought. Im almost sure of it but I'll check.
Mar-21-06  kansasofunitedstates: The computer should not have moved the horse on play 11! The horse cannot be protected!

The computer did not "look for the check-mate" on move 16! The game was certainly over!

Mar-21-06  goldenbear: Karpov sure knows what "winning" means. Karpov -- possibly the reincarnation of Pillsbury?

  tamar: Computer, know your classics! The machine hadn't been briefed on moves 35-38 of Capablanca vs Tartakower, 1924

Karpov probably saw the winning pattern with Kg5 instantly when he offered the a pawn.

Mar-16-07  argishti: karpov crushed the machine! wat a crushing game!
Mar-17-07  themanfrommanila: Very few players could beat Karpov in an endgame.
Mar-17-07  RookFile: <argishti: karpov crushed the machine! wat a crushing game!>

Actually, he didn't. If memory serves, the published accounts of this game say that the computer could have forced a draw about move 38 by repetition. The computer thought it was better, and played for the win.

Looking at the game, I guess what this means is 38..... Rb3+ 39. Kf4 Rb4 and the question is, try to find a better move than 40. Ke3.

Mar-17-07  chessamateur: <64 Squares> This is a game of Deep Thought's. It was G/60 played on Feb. 2, 1990.

"Surprisingly, by move 16 Deep Thought had a chance to make a sacrifice that would have placed Anatoly under tremendous pressure. Had the game been played with a regular time control, then Deep Thought would have made the sacrifice. The 3-workstation version of the program that played Garry potentially could find the sacrifice within the game time, assuming that we had got it working for the match. It is amazing how a minor difference could have changed the history dramatically.

Since Deep Thought could not find the sacrifice over the board, it played the second best move and Anatoly obtained a slight edge."

"Behind Deep Blue", pp120-1

After an 18 ply search, Ruffian 1.0.1 (P4 2.4Ghz, 256Mb hash) and Crafty 19.3 (Dual Athlon MP 2000+, 768Mb hash) both like 16...Nf5. Are they missing something, or is there a mistake in the book?

*end of quote*

It's 2009 now, and Rybka 3 still can't see anything better than 16 ... Nf5 (+0.12 after 17 ply search). Am I even looking at the right move?

(PS The endgame has many mistakes from both sides... eg 56 Ke5 wins, or 55 ... a3 or 59 ... h3 draws).

Feb-24-09  WhiteRook48: is Computer a Computer?
Sep-09-09  WhiteRook48: where's the repetition?
May-28-12  maxi: Possibly it's my lack of chess understanding talking, but I don't care for Karpov's opening play.
May-28-12  Call Me TC: Karpov was smart enough to take on the best computer when it could still be beaten.
May-28-12  Eduardo Leon: The beautiful pawn sacrifice <51.h5 gxh5+ 52.♔f5> (when already a pawn down!) reminded me of Capablanca vs Tartakower, 1924
May-28-12  RandomVisitor: After 16...Nf5 the position is complicated, even for a computer:

Dec-15-12  rwbean: Houdini 1.5a after about an hour thinks 16...Nf5 is the best move, equal (16...Qxb2 is about +0.5 for White).

Jan-22-18  paavoh: <looks like he isn't doing much more then waiting for a mistake>

I like Karpov's games very much, grew up following the K-K matches in 70's and 80's. However, when I try to emulate him by "waiting for a mistake", I usually get clobbered...

Dec-28-18  rwbean: Stockfish 10 after 97 minutes, 47 ply ... 16... ♘f5 17. ♗f4 h6 18. ♗b5 g5 19. ♘d7 ♕a7 20. ♘xf8 ♖xf8 21. ♗d2 ♘cxd4 ... sacrificing the exchange, but the evaluation is still 0.00. I don't think there was anything there.

"Behind Deep Blue" was published in 2002.
