Candidates 2018 Round 7: Can anyone stop Fabi?

When Vishy Anand won the Candidates in 2014 and also the 8-player round robin in Mexico in 2007 there was one thing that he did really well - he kept control. This is something that Fabiano Caruana is executing to perfection at the Candidates 2018. While Levon Aronian, Vladimir Kramnik and even Wesley So are showing flashes of brilliance, it is Caruana who is truly looking rock solid. He now has a +3 score and at the half-way mark looks like the favourite to win the title. He is closely followed by Shakhriyar Mamedyarov who is on 4.5/7. Rest of the players are on 3.5/7 or below. It's a race between Fabi and Shakh.
