Kolkata :Sharing the secret of his success at the World Championship, Indian chess wizard Viswanathan Anand on Monday said he unnerved rival Veselin Topalov by playing fast and aggressively towards the climax of title battle.
"Inevitably, you start to adapt your opponent's game after a few rounds. I was observing him for 7-10 games. In the 10th game, I switched back to play faster and fought back... It seemed to have an affect on him (Topalov)," Anand said about his secret of the success in Sophia in May.
