Chess first of all teaches you to be objective.

Oh! this opponent, this collaborator against his will, whose notion of Beauty always differs from yours and whose means (strength, imagination, technique) are often too limited to help you effectively! What torment, to have your thinking and your phantasy tied down by another person!

For success I consider three factors are necessary: firstly, an awareness of my own strengths and weaknesses; secondly, an accurate understanding of my opponent's strengths and weaknesses; thirdly, a higher aim than momentary satisfaction. I see this aim as being scientific and artistic achievements, which place the game of chess on a par with other arts.

Psychology is the most important factor in chess.

The fact that a player is very short of time is to my mind, as little to be considered as an excuse as, for instance, the statement of the law-breaker that he was drunk at the time he committed the crime.

A lifetime in not enough to learn everything about chess.

Chess, like other arts, must be practiced to be appreciated.
