Igor Efimov is a decorated chess Grandmaster from Monaco. He was born on March 29th, 1958 in Baku, Azerbaijan. He officially earned the title as International Grandmaster of Chess in 2002 but his involvement in the game extends beyond just playing. He served as the president of the Monaco Chess Federation from 2001 to 2007 and has also represented Monaco in the Chess Olympiad multiple times.
Efimov has won multiple championships in countries including Yugoslavia, Italy, and Monaco. He wasn't always a citizen of Monaco though. He moved there in 1992 and changed his nationality in 1995.
