Norway Chess 2013 (from ChessBase News)
Everyone talks Carlsen, but why are few people mentioning Karjakin, who just won the Norway 2013 tornament?
In my view, it is currently a waste of time to argue "who is best?" because Carlsen blundered in the endgame against Wang Hoa. And Wang Hao played inconsistently, beating Carlsen, Anand and Svidler, but losing to Hammer! A win there would have placed him on 5.5 / 9, tying with Nakamura for 3rd place.
About Kararkin, from Wikipedia:
Karjakin was born in Simferopol. He learned to play chess when he was five years old and became an IM at age eleven and eleven months. 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 programDeep 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".
