To my surprise I found that when other top players in the precomputer age (before 1995, roughly) wrote about games in magazines and newspaper columns, they often made more mistakes in their annotations than the players had made at the board.

Nowadays games immediately appear on the Internet and thus the life of novelties is measured in hours. Modern professionals do not have the right to be forgetful - it is 'life threatening'.

Chess is a unique battlefield for human minds and computers - human intuition, our creativity, fantasy, our logic, versus the brute force of calculation and a very small portion of accumulated knowledge infused by other human beings. So in chess we can compare these two incompatible things and probably make projections into our future. Is there danger that the human mind will be overshadowed by the power of computers, or we can still survive?

Though I would have liked my chances in a rematch in 1998 if I were better prepared, it was clear then that computer superiority over humans in chess had always been just a matter of time.

The ability to work hard for days on end without losing focus is a talent. The ability to keep absorbing new information after many hours of study is a talent.

Russia is a mafia state today, and Putin is its top godfather.

From Ukraine to Syria, he [Vladimir Putin] is behaving like the world's new general and celebrating victories, while the American president sits on the sidelines and Europe sleeps. The West's behavior toward Putin is political and moral capitulation.
