Another reason for a rather unusual number of draws is an extraordinarily peaceful attitude of Kramnik and Vallejo. If the former one may be compared with 'a satisfied tiger', the latter one tries hard not to become a dinner.
The largest quantity of militant games is produced by Radjabov. It seems that Radjabov is a true showman deep in his heart and this meets a sheer sympathy from numerous chess lovers - the grandmasters are playing for them! Shirov is of the same specie but Alexei is much luckier for a while. Leko and Kramnik still believe in possibility of their match and they are hiding their trump cards. Perhaps, Kasparov does not believe in anything but he tries not to discover himself provisionally. If it is possible to put the things so, Topalov demonstrates a moderate aggression alternating the militant games with more calm ones.
Many people complained about a low effectiveness of the tournament and a huge number of short draws. Well, if someone expected bloodshed in the second round, the one was mistaken! The draws were agreed before the move 25. Perhaps, it does make sense to restore tournament practice of the XIX century when the draws were played over? Or, perhaps, to introduce soccer system when calculating points?
Of course, Kramnik wanted to recoup himself after his not quite successful performance in Wijk aan Zee event. He kept to his strategy in the second round, played solidly and avoided unnecessary risk. He took over leadership after having beaten his chief competitor Peter Leko. Then it took him few draws more to achieve the first place.
