In anticipation of the 2013 World Championship match between Anand and Calsen starting in a couple of days, I was looking at the history of games between the two players.
In chessgames.com, I was able to find 62 games between 2005 and 2013, out of those 29 classical games, with Anand beating Carlsen 6 to 3, and 20 draws. The last year of course saw the shift of results in favor of Carlsen.
Here, I show two games: the first game shown between them in 2005, which seems like a rapid game, and the last game this year in Tal Memorial which was a smooth win for Carlsen. These games show how much Carlsen progressed along those years.
