GM Hikaru Nakamura is an American of Japanese descent. He is a four-time United States Chess Champion, who won the 2011 edition of Tata Steel Group A, and represented the US at five Chess Olympiads, winning a team gold and two team bronzes. He has also written a book called Bullet Chess: One Minute to Mate. At age 10, Nakamura became the youngest player to achieve the title of chess master from the USCA (the record stood until 2008 when Nicholas Nip achieved the title at 9 years and 11 months.) In 2003, at age 15 years and 79 days, Nakamura became the youngest American to earn the Grandmaster title, breaking the record of Bobby Fischer (Nakamura's record was subsequently broken by Fabiano Caruana in 2007).
