New Delhi (PTI): The tension, the rush of emotions and the uncertainty of results in the World Championship makes it feel a bit like stock market, says Indian chess ace Viswanathan Anand, who will defend his crown in October.

The world number one, who became the World Champion last September, said although he is not feeling the pressure of the competition to be played in matchplay format in Bonn, Germany, he was "working harder" to defend his title against Vladimir Kramnik of Russia.

"There was a cold shower when I lost my first game in the Wijk Aan Zee and then I drew some 5-6 games after a gap of couple of months. So it is very important to have memories and experience and the feel of the tension of the big chess events.

"You remember big match tensions... experience becomes important. It's a bit like stock market as match can turn either way, so the emotions, anxiety, experience and all these things become important," said Anand on the sidelines of the nationwide launch of 'NIIT Mindchampions Academy 2008-09 series'.

Anand said despite being top-placed he does not have any advantage against the second-ranked Kramnik in the World championships.

"So far it is only Anand versus Kramnik. You have to forget that you are a World Champion and it's (the match) not between the World Champions versus a challenger," he said.
