Anand continued to shares the third spot along with Vassily Ivanchuk of Ukraine.

Anand shares the fourth spot in rapid on 4 points.It was another dull day in the blindfold and a 'white day' in the rapids. All the blindfold games ended in draws and all playing white in the rapid games won giving six decisive results in the end.

The blindfold had the best hopes for Anand as he played white.However, in a closed Ruy Lopez, the Indian ace faced a new maneouvre and called his 13th move a bad one. As it happened Aronian had a draw in just 17 moves.

The result was never in doubt in the minds of kibitzing pundits and Aronian wrapped the issue showing his technical acumen.
