  Honza Cervenka: Impressive positional play of Karpov.
Dec-30-05  foolishmovesss: Outstanding. Home prep no doubt. how would you feel as black after d6? I think i would resign. Another great Karpov squeeze. Ribli probably should have played Qe6 instead of Qxa1. You have to believe that at this point in Karpovs carrer, that if he wanted to trade queens he must have an advantage after the exchange. I noticed Qe6 in the database 8 times, Ribli was the only person who went with the trade. Must have been looking for a draw.

--Foolish

Aug-07-09  Billy Ray Valentine: Wow! Trademark boa constrictor play from Karpov.

Where does black commit the decisive error?

Rybka has problems in deciding... Ribli also.

Jul-08-11  ozmikey: Absolute vintage Karpov. If there is an error as such from Black it's probably simply 17...Qxa1 - without the queens it's so much harder for him to organise any counterplay against the intended bind on the queen-side.
Jul-08-11  SimonWebbsTiger: Looking in Informator 30/99 (where the game is classified under ECO code A39, btw), annotator Ostojic mentions that Karpov introduced a novelty with 16. Rb5. Ribli-Timman, Tilburg 1980 saw 16...Qa6 with the Dutchman holding an easy draw; whilst in Bagirov-Mihalcisen, Tbilisi 1980 black played 17...Qe6 and also drew.

19...Rb7 was a suggested defence

Apr-20-12  Everett: Absolutely creepy, how Karpov crushes even the best players. To think he actually did it to Kasparov for years as well.
Apr-21-12  rilkefan: If black gives up a7 and b7 for b2 does the 5-vs-4 kingside pawn structure leave white with a winning endgame advantage in practice or theory?
Apr-21-12  King Death: <rilkefan> With which pieces left on the board? In the single rook ending 4-3 is nearly always a theoretical draw but even GM level players have lost that, (Capablanca vs Yates, 1930) and (Duras vs Capablanca, 1913) are examples. As far as I can remember I haven't seen any 5-4 rook endings (with an extra pawn on the e file for the defense and a d pawn for the stronger side) but the more pawns, the more winning chances is probably a good general guide.
Apr-21-12  rilkefan: <King Death> - presumably whatever black can most advantageously arrange while making the material concession. Maybe Q+R+5p vs Q+R+4p? I don't know if it's even possible, as the immediate ...Bxb2 (my first thought, and the lead-in to my above) just loses to Qd2.

FWIW, Stockfish sees only +0.2 at a depth of 27 after 17...Qe6 vs almost +1 after 17...Qxa1.

Apr-21-12  King Death: <rilkefan> Playing against an ordinary master much less a top GM I'd have to have a pretty good reason to go into the ending with 17...Qa1 because Black has no winning chances and White can "massage" his opponent for a long time. Sure Ribli's a strong GM and I'm just an ordinary master so he probably saw something (or thought he did) that us regular folks missed.
Jul-22-15  SpiritedReposte: Just knowing this game was played in 1980, not even looking at the names, you can tell its Karpov.
Sep-29-18  cunctatorg: The battle of Karpovgrad!

Anyways this is a proper game for GOTD...

May-02-19  Woodrow887: Incredible grind by white! Very impressive
Oct-24-20  fisayo123: Another impressive display by Karpov. He effortlessly wipes out one of the top players in the world and its hard to pinpoint any big mistakes from black

Karpov is white.
