Career
Karpov learned to play chess at the age of four. His early rise in chess was swift, as he became a Candidate Master by age eleven. At twelve, he was accepted into Mikhail Botvinnik's prestigious chess school, though Botvinnik made the following remark about the young Karpov: "The boy does not have a clue about chess, and there's no future at all for him in this profession." Karpov acknowledged that his understanding of chess theory was very confused at that time, and wrote later that the homework which Botvinnik assigned greatly helped him, since it required that he consult chess books and work diligently. Karpov improved so quickly under Botvinnik's tutelage that he became the youngest Soviet National Master in history at fifteen in 1966; this tied the record established by Boris Spassky in 1952.
Karpov remained a formidable opponent (and the world #2) until the early 1990s. He fought Kasparov in three more world championship matches in 1986 (held in London and Leningrad), 1987 (held in Seville), and 1990 (held in New York City and Lyon). All three matches were extremely close: the scores were 11½ to 12½ (+4 −5 =15), 12 to 12 (+4 −4 =16), and 11½ to 12½ (+3 −4 =17). In all three matches, Karpov had winning chances up to the very last games. In particular, the 1987 Seville match featured an astonishing blunder by Kasparov in the 23rd game. In the final game, needing only a draw to win the title, Karpov cracked under pressure from the clock at the end of the first session of play, missed a variation leading to an almost forced draw, and allowed Kasparov to adjourn the game with an extra pawn. After a further mistake in the second session, Karpov was slowly ground down and resigned on move 64, ending the match and allowing Kasparov to keep the title.
In their five world championship matches, Karpov scored 19 wins, 21 losses, and 104 draws in 144 games.
Karpov is on record saying that had he had the opportunity to fight Fischer for the crown in his twenties, he (Karpov) could have been a much better player as a result (in a similar way as Kasparov's constant rivalry with him helped Kasparov to achieve his full potential).
