Former world chess champion placed on a blacklist by Moscow's financial intelligence services. Garry Kasparov is famous for his long duel in the 1980s with another Soviet chess legend, Anatoly Karpov.
He subsequently supported Vladimir Putin and became a deputy in the Russian president's party. Most of the major opponents remaining in Russia are imprisoned. Some, like Boris Nemtsov and Alexei Navalny, are dead. The others ended up going into exile. In 2013, fearing legal action, he left Russia and now lives in the United States.
