The World Chess Championship begins today in Sochi. For the next 20 days, incumbent Magnus Carlsen of Norway, rated as the best player in history, and five-time World Champion Viswanthan Anand of India will be battling for the title.
The Match is being played over a maximum of twelve games, with the winner being the first to score 6.5 points or more. The match is seen as the last chance for Anand to recapture the title from 23-year old Carlsen, after losing to him in Chennai last year.
This is the second world championship that will be played with Daniel Weil’s World Chess set.
