Radjabov's knight sacrifice, 21...Ngxe5, was praised by several strong players for its bravery, including English grandmaster Nigel Short: Radjabov plays very imaginatively... he just won't give up, he is extremely tenacious and will always find a way to muddy the waters to throw you off track. He is very good at finding disconcerting moves. Here he unbalances Kasparov completely, disturbing his rhythm of play... That was the point of Radjabov's sacrifice – it was not sound but it gave him these practical chances. However, the sacrifice was called "desperation" by GM Miguel Illescas, and according to Chessbase.com, "The Grandmasters we have talked to praised Radjabov's resilience in a bad position but criticized the game as unworthy of a prize because it was based on blunders."
