Bangalore:Having endured a rather unproductive year in terms of achievement, World chess champion Viswanathan Anand says he is working to raise his game and play aggressively to overcome tough opponents at the World Chess Championship next year.
"I need to up my game and play aggressively. Veselin Topalov is very aggressive player. Vladimir Kramnik is a tough opponent as well. The preparations are on," said Anand, who has been preparing in right earnest for the two million euro World Championships in Sofia, Bulgaria next April.
