Facing a point deficit with just four games to go, five times world champion Viswanathan Anand is in a now-or-never situation in the World Chess Championship match against Magnus Carlsen at Sochi, Russia. With the scores favouring Carlsen 4.5-3.5 after eight games in the 12-game match, Anand is now under serious pressure to score at least one victory, and if that does not happen in the next two games, it might be already too late.Ahead of the ninth game tomorrow, it is not only the match situation which is a worrying factor for Anand but also Carlsen's preparation. The Indian ace had come up with a fine new idea to win the third game but since then Carlsen seems to have caught the preparation bug too.
