The other interest in the final round was seeing if Anish Giri could go through the event with 14 straight draws. He did this by drawing with Topalov, although the fact that he was the only unbeaten player in the tournament is probably not as special as it should be.
As for my pre tournament predictions, I got Karjakin very wrong (he was in my bottom 3). I did have Caruana and Anand as possible winners, but I also thought Topalov and Nakamura were in with a chance (they were struggling from the start). My other potential winner, Lev Aronian did start well, but fell away at the end.
Although it is a long way out I feel that Carlsen will retain his title against Karjakin. However it may be a matter of motivation and preparation, and Karjakin may hold the edge in both categories.
