Garry Kasparov is a former world chess champion, who many consider to be the greatest chess player of all time. He was born in Azerbaijan in the 1960s, which was at the time part of the Soviet Union. For nearly 20 years he was ranked No. 1 in the world. Kasparov’s most popular match became a defeat for him when he lost to the IBM supercomputer Deep Blue in 1996.
In 2005, Kasparov retired - and became a writer and political activist. He created a social movement which opposes Putin's government and which has the goal of securing democratic elections in Russia.
In 2007, Kasparov entered the presidential race in Russia - but withdrew his candidacy just a few weeks later. After years of pressure from the Kremlin and having been detained several times during street protests, he left Russia. Kasparov has been living in the United States since 2013.
