When two top grandmasters meet, statistics show that a decisive result happens in just over one in three games. That is roughly the rate in world title matches and the strongest tournaments. So in a 10-game match, you would expect about three decisive games.

In practical terms, that purely probabilistic calculation tends to be modified by other factors, among which the fear of suffering the first defeat is the strongest. Whoever loses first can easily become desperate and go downhill quickly.

That is the only explanation I can offer for the dullness of the first two games in the Kramnik-Shirov match. Here we have seen the two most imaginative and brilliant young players in the world playing in uncharacteristically cautious style. Perhaps each is trying to tempt the other to take all the risks, but for both men it is a dangerous strategy. If the briefness of the encounter made them nervous at the start, then each draw will only increase that nervousness. Already they have only eight games left, and the terrible consequences of a loss grow with every draw. Both the players and spectators would have enjoyed it more if they had thrown caution to the winds from the start.

The only interesting moment in game two came when Kramnik decided to avoid 19...Bxh2+ 20.Kh1 Rxe6 21.Qxe6+ Kh8 22.g3 Bxg3 23.fxg3 Qxg3.

White: Alexei Shirov

Black: Vladimir Kramnik
