Anatoly Yevgenyevich Karpov, PhD (Russian: Анато́лий Евге́ньевич Ка́рпов, Anatolij Evgen'evič Karpov; born May 23, 1951) is a Russian chess grandmaster and former World Champion. He was the official world champion from 1975 to 1985.
He played three matches against Kasparov for the title from 1986 to 1990, before becoming FIDE World Champion once again after Kasparov broke away from FIDE in 1993. He held the title until 1999, when he resigned his title in protest.
For his decades-long standing among the world's elite, Karpov is considered by many to be one of the greatest players of all time. His tournament successes include over 160 first-place finishes. He had a peak Elo rating of 2780, and his 90 total months at world number one is second all-time behind only Garry Kasparov since the inception of the FIDE ranking list in 1970.
