So why did they do it? Isn't the chess world being too hard against Topalov and Danailov? Hans Ree has these takes:
One can well imagine Kramnik being so angry at Topalov and his manager Danailov that he gladly offered his services to Anand. But Kasparov and Carlsen, why did they get involved? One can only speculate that they feared a reign of terror of the Topalov-Danailov tandem with more toiletgates or other tricks if Topalov became world champion.Topalov could very well understand Kramnik's assistance but it's a real blow seeing Kasparov and Carlsen siding with Anand who expects nothing in return. And yes, that really hurts!
With such an over-kill of high-class manpower in the fight against Topalov, one would almost pity him.
