Kasparov's Ultimate Immortal Game? Yes!
Garry Kasparov: If Topalov had not taken the Rook, the game could have finished in a draw: Veselin would have had half a point more, I - half a point less. He would have win a little bit, I would have lost a little bit, but chess and chess amateurs would have lost a lot. However, Caissa was kind to me that day.. . I do not know what I was rewarded for, but the development of events became forced after the capture on d4.
