Sergey Karjakin is youngest grandmaster in history, achieving the title at the age of twelve years and seven months

meet Sergey Karjakin (Ukrainian: Сергій Карякін; Russian: Сергей Карякин; born January 12, 1990 in Simferopol) is a Ukrainian chess grandmaster. He was a chess prodigy and holds the record for the youngest Chess Grandmaster in history, achieving the title at the age of twelve years and seven months. In the April 2009 FIDE rating list he is ranked 23rd in the world, third in Ukraine, and the second junior (under 20) in the world.

More about him:
Karjakin learned to play chess when he was five years old and became an IM at age eleven. In 2001, he won the World Chess U12 championship. He first attracted attention in January 2002, when he was the official second of fellow Ukrainian Ruslan Ponomariov during the final of the 2002 FIDE World championship, though Karjakin had only just turned twelve at the time. By scoring GM norms at the Aeroflot tournament in Moscow later that month, the Alushta tournament in May 2002 and the international tournament in Sudak in August 2002, he surpassed Bu Xiangzhi to become the youngest grandmaster in the history of chess at the age of twelve years and exactly seven months—a record that still stands. At age fourteen he defeated the reigning world champion, Vladimir Kramnik, during the 2004 Dortmund Sparkassen Chess Meeting, in a blitz game (ten minutes for the entire game, plus five seconds per move). Also in 2004, Karjakin was the only human to win against a computer in the Man vs Machine World Team Championship in Bilbao, Spain, where he was the youngest and lowest rated player. He won against the computer program Deep Junior. Later that year Karjakin finished second to Boris Gelfand at the Pamplona, Navarra tournament, held from December 20 to December 29.
Karjakin entered the world's top 100 in the April 2005 FIDE list, where he was number 64 in the world with an Elo rating of 2635. He scored 8.5 (7-3-1) to win the Young Stars of the World 2005 tournament held in Kirishi, Russia from May 14 to May 26. Practicing before the tournament with Nigel Short in Greece, Karjakin was involved in a car accident on the way to the Athens airport and suffered minor injuries. Afterwards, Short remarked that he had "almost changed the path of chess history by allowing the future World Champion to be killed while in my care". During the Chess World Cup 2007, which served as a qualification tournament for the World Chess Championship 2009, Karjakin reached the semi-finals, in which he lost to Alexei Shirov. On the January 2008 FIDE rating list, published just before Karjakin's eighteenth birthday, he passed for the first time the 2700 mark, often seen as the line that separates "elite" players from other grandmasters, with a new rating of 2732 and a world rank of 13. In July 2008 Karjakin played a ten game rapid chess match against GM Nigel Short and won convincingly with a score of 7.5-2.5. In February 2009 he won the A group of the Corus chess tournament in Wijk aan Zee (category XIX) with a score of 8/13.
