Mikhail Mikhailovich Youzhny 

(born June 25, 1982) is a professional Russian tennis player, noted for his consistency and all-court play style. He has been coached by Boris Sobkin for 17 years.
Youzhny's highest singles ranking is World No. 8, achieved initially in January 2008 and again in October 2010. He is one of the few active players to have reached the quarter-finals or better in all 4 Grand Slam tournaments.
Youzhny was a member of the winning Russia Davis Cup team in both 2002 and 2006, including a victory over Paul-Henri Mathieu from two sets down in the fifth and decisive rubber of the former 3–6, 2–6, 6–3, 7–5, 6–4.

Vladimir Borisovich Kramnik 

 ( born 25 June 1975) is a Russian chess grandmaster. He was the Classical World Chess Champion from 2000 to 2006, and the undisputed World Chess Champion from 2006 to 2007. He has also won the two strongest chess tournaments (by rating strength) in history: the 2009 Mikhail Tal Memorial and the 2010 Grand Slam Masters Final. He has won three team gold medals and three individual medals at Chess Olympiads. In October 2000, he defeated Garry Kasparov in a match played in London, and became the Classical World Chess Champion. In late 2004, Kramnik successfully defended his title against challenger Péter Lékó in a drawn match played in Brissago, Switzerland. In October 2006, Kramnik, the Classical World Champion, defeated reigning FIDE World Champion Veselin Topalov in a unification match, the World Chess Championship 2006. As a result Kramnik became the first undisputed World Champion, holding both the FIDE and Classical titles, since Kasparov split from FIDE in 1993. In 2007, Kramnik lost the title to Viswanathan Anand, who won the World Chess Championship tournament ahead of Kramnik. He challenged Anand at the World Chess Championship 2008 to regain his title, but lost.
Kramnik qualified for the Candidates Tournament which determined the challenger to face World Champion Anand in the World Chess Championship 2012. He advanced to the semifinals before losing to Alexander Grischuk.
