Zurich: Five-time world champion Viswanathan Anand began his campaign in the Zurich Chess Challenge as he went down to Armenian Levon Aronian in the first round here.
It turned out to be a bad day in office for Anand who lost his way in the middle game and his counter-play bid did not materialise. The loss may prove quite costly as every win here is worth two points for the overall standings.
World champion Magnus Carlsen started from where he had left the classical chess. His last outing being the world championship match in Chennai, Carlsen did not show any rustiness coming back to the board and outplayed Boris Gelfand of Israel in a remarkable game.
