This is in addition to PhishMaster's answer elsewhere:
According to https://www.chess.com/players/shakhriyar-mamedyarov, Shakhriyar Mamedyarov was born in Sumgait, Azerbaijan SSR, Soviet Union, on April 12, 1985. He is the Azerbaijan’s top player, and has becaome the only player ever to win the World Junior Championship twice (winning it in 2003 and 2005). He became a Grandmaster in 2002.
According to https://www.chess.com/players/teimour-radjabov, Teimur Radjabov was born in Baku, Azerbaijan SSR, Soviet Union, on March 12, 1987, the same city as former world champion Garry Kasparov. By 2001, he had earned his Grandmaster norms (at young age of 14) and was competing in Group B of the Corus Tournament at Wijk aan Zee.
It is noteworthy that when he was 16 years old, Radjabov was one of seven participants at Linares 2003. In that tournament, in perhaps one of the most famous games of his career, Radjabov has defeated Garry Kasparov (his fellow Baku native) in 39 moves with the black pieces. The game has been voted the best of the tournament.
Along with other fellow Azerbaijani players, Shakhriyar Mamedyarov and Teimur Radjabov have led their nation to gold medals in the 2013 and 2017 European Team Chess Championship. The two represent the nation’s best chance at a world champion among the current crop of top players.
