There is no one that can argue against this statement: Magnus Carlsen is the all time best Chess player in the world!
The 22-year-old Norwegian won the World Chess Championship 2013 in India today after beating Viswanathan Anand. Carlsen is the No. 1 ranked player in the world, and has the highest rating in history (2.872).
I took a picture with Carlsen in May, when he came to Stavanger to play in Norway Chess 2013
