Teimour Radjabov was the biggest danger to the leading Levon Aronian in the final rounds. After 36 games the Armenian was 1.5 points ahead of his Azeri rival, and two ahead of last year's winner Magnus Carlsen. In round 37, the penultimate, Radjabov lost with black to Sergey Movsesian, while Carlsen drew against Ian Nepomniachtchi. Aronian's loss (with the white pieces) to Sergey Karjakin did not change the fact that he was now unassailable, a point and a half ahead of the other two.
