As the whole of the chess world must know by now, we have a new World Champion in the shape of 22-year old Magnus Carlsen (his 23rd birthday is next Saturday). He beat the previous champion Vishwanathan Anand by 6½ points to 3½, an unassailable lead in their 12-match championship in Chennai. Nicknamed the 'Justin Bieber' of chess, he will certainly bring a new impetus to chess around the world and we may find his success encourages more people to take up the game.
Even the BBC has woken up to the fact that there's a new chess champion.
Magnus' own website gives a lot more information about him.
