American grandmaster Fabiano Caruana beat Russia’s Alexander Grischuk in the final round of the Berlin Candidates Championship to complete the 14-game double round-robin with nine points, one ahead of Azerbaijan’s Shakhriyar Mamedyarov and Russia’s Sergey Karjakin.

He will now challenge for Magnus Carlsen’s world chess championship to be held in London from in November 9-28.

Caruana, 25, led the eight-man field from start to finish and will be the first American to compete for a world championship since Bobby Fischer in 1972. He ended up with 9 points from 14 games.

This will also be the first world championship match with two players representing a Western country since Alekhine - Euwe in 1937.
