Rejuvenated after his third victory in the previous round, former world champion Viswanathan Anand will take on Fabiano Caruana of United States in a crunch game in the tenth round of the Candidates Chess tournament being held in Moscow. With just five rounds remaining, experts say a victory against Caruana can definitely seal the tournament for Anand. As things stand, Anand and Karjakin share the lead on 5.5 points apiece while Caruana and Aronian are on the heels of the two leaders a half point behind.Rest of the contestants have little chance at this stage to get the top spot that will guarantee a match against Magnus Carlsen of Norway for the world title.
