Five-time world champion Viswanathan Anand has moved into the sole lead position after the end of the second round of Zurich Chess Challenge tournament. After beating Levon Aronian of Armenia in a mere 19 moves in the first round, the Indian ace outwitted Anish Giri of Holland in the second round in Zurich. With back-to-back victories, Anand moved to four points under a special scoring system that gives two points for a victory and one for a draw in rapid games. After the rapid section is over, the players will play a return blitz event, in which one point will be awarded for a win and half for a draw. The cumulative results will be added to determine the winner this year.
