World Champion Viswanathan Anand suffered a rare loss, going down to Vassily Ivanchuk of Ukraine in the third round of the fourth Bilbao Final Masters here. After two fighting draws, Anand did not achieve much in the opening. And once his position worsened Ivanchuk played in machine-like fashion to force a victory.
After his second successive victory, Ivanchuk shot in to sole lead with seven points. Overnight joint leader Aronian, meanwhile, slipped to the second spot with five points, enjoying a two-point lead over nearest rivals Nakamura and Vallejo Pons.
Carlsen and Anand are currently languishing at the bottom of the tables with just two points that came from two draws in the first two rounds.
