Wijk Aan Zee (The Netherlands): World champion Viswanathan Anand crashed through the defences of Fabiano Caruana of Italy to jump to the joint second spot, after the end of the third round of the premier section of the Tata Steel Chess tournament, here, on Tuesday.
Anand showed his sublime touch and Caruana, who started the tournament ahead of Anand in world rankings, fell behind the world champion following the loss in live ratings.
It turned out to be another good day for debutante P. Harikrishna as he survived an inferior position before splitting points with world No.3 Levon Aronian of Armenia.
Russian Sergey Karjakin surged ahead of the field at the expense of Wang Hao of China, who went for unwarranted complications from what looked like an equal position.
With his second victory in three days, Karjakin moved to sole lead with 2.5 points. He is now followed by world No.1 Magnus Carlsen of Norway, Anand and Harikrishna, all of whom have two points each.
Aronian shares the fifth spot now along with Hikaru Nakamura of the United States and Dutchmen Erwin L'Ami and Ivan Sokolov.
Not far behind are five other players, including Caruana and Anish Giri, of Holland with one point apiece.
