Kasparov became the youngest ever undisputed World Chess Champion in 1985 at age 22 by defeating then-champion Anatoly Karpov.

In 1997 he became the first world champion to lose a match to a computer under standard time controls, when he lost to the IBM supercomputer Deep Blue in a highly publicized match. He continued to hold the Classical World Chess Championship until his defeat by Vladimir Kramnik in 2000. In spite of losing the title, he continued winning tournaments and was the worlds highest-rated player when he retired from professional chess in 2005.
After Kasparov retired, he devoted his time to politics and writing. He formed the United Civil Front movement, and joined as a member of The Other Russia, a coalition opposing the administration and policies of Vladimir Putin. In 2008, he announced an intention to run as a candidate in that years Russian presidential race, but failure to find a sufficiently large rental space to assemble the number of supporters that is legally required to endorse such a candidacy led him to withdraw. Kasparov blamed official obstruction for the lack of available space. Although he is widely regarded in the West as a symbol of opposition to Putin, he was barred from the presidential ballot, as the political climate in Russia makes it difficult for opposition candidates to organize.Kasparov is currently chairman for the Human Rights Foundation and chairs its International Council. In 2017, he founded the Renew Democracy Initiative (RDI), an American political organization promoting and defending liberal democracy in the U.S. and abroad. He also serves as chairman of the group.Kasparov is a frequent critic of U.S. professor emeritus of Russian studies Stephen F. Cohen, whom he describes as a Soviet and Russian apologist. Kasparov and Cohen participated in a Munk Debate in 2015 over the issue of reengaging or isolating Russia, with 52% of the audience siding with Kasparovs argument of isolating Russia, compared to 42% before the debate. In 2014, he obtained Croatian citizenship. He lives in New York City and travels often.
