Since retiring from chess, Kasparov has devoted his time to writing and politics. Kasparov stood unsuccessfully for FIDE president in 2013–2014. Kasparov coached Carlsen in 2009–10, during which time Carlsen rose to world no. Despite losing the PCA title, he continued winning tournaments and was the world's highest-rated player at the time of his official retirement. He continued to hold the "Classical" world title until his defeat by Vladimir Kramnik in 2000. In 1997, he became the first world champion to lose a match to a computer under standard time controls when he was defeated by the IBM supercomputer Deep Blue in a highly publicised match.

Kasparov held the official FIDE world title until 1993, when a dispute with FIDE led him to set up a rival organisation, the Professional Chess Association. He defended the title against Karpov three times, in 1986, 19. Kasparov became the youngest-ever undisputed world champion in 1985 at age 22 by defeating then-champion Anatoly Karpov. Kasparov also holds records for the most consecutive professional tournament victories (15) and Chess Oscars (11).

From 1984 until his retirement from regular competitive chess in 2005, Kasparov was ranked world no. His peak FIDE chess rating of 2851, achieved in 1999, was the highest recorded until being surpassed by Magnus Carlsen in 2013.
