Go up one level in this thread


Kasparov intervew (some words after Corus 1999)

He expressed the belief that due to computers his
preparation is now the strongest it has ever been. "I can go into positions
I wouldn't have dared play before. I do a lot of work and thanks to the
computer, I just know the outcome of certain positions." (he cited his draw
against Kramnik and his 12. ...e6 against Shirov as examples of positions
which he could analyse only with the aid of computers and that he would not
have thought to play before.
