Norway's Magnus Carlsen plays with a phone in Oslo
Norway's Magnus Carlsen plays with a phone in Oslo February 25, 2014. Carlsen, the world's 23-year-old reigning chess champion, has launched an app based on his own past games to make chess more popular, but he'd prefer its players not get good enough to beat him. Carlsen, whose talent and boyish good looks have earned him lucrative sponsorships deals and front-page coverage in his native country, is king of the roost in the chess world since beating Viswanathan Anand of India in November.
