Former chess champion turned Russian opposition leader Garry Kasparov has won a big-money charity television quiz in neighbouring Georgia, the programme's producer said on Tuesday.

Kasparov managed to answer all the questions correctly on the quiz programme "Who Wants to Win 20,000?", a Georgian equivalent of the "Who Wants to Be a Millionaire?" television game show.

His entire winnings of 20,000 Georgian lari (11,265 US dollars, 8,325 euros), a large prize in the ex-Soviet republic, will go to fund medical care for local children.

Kasparov, a Soviet-era world chess champion, has become one of the Kremlin's most outspoken critics -- a stance that is admired in pro-Western Georgia, which fought a war with Russia in 2008.

Programme producer Giorgi Khaburdzania described Kasparov as a "living genius" and said that he expected a huge audience for the show, which is due to be broadcast by Georgia's Rustavi 2 television station next week.

During his visit to Tbilisi, Kasparov also lectured at a local university, where he said that he believed that Russian-Georgian relations would not improve while the current authorities remain in the Kremlin.

"Georgia has gone a long way with democratic reforms and its economy has achieved progress, but Russia has missed all the opportunities to become a democratic country," he said in comments reported by Rustavi 2.
