During the course of many years I have observed that a great number of doctors, lawyers, and important businessmen make a habit of visiting a chess club during the late afternoon or evening to relax and find relief from the preoccupations of their work.

Ninety percent of the book variations have no great value, because either they contain mistakes or they are based on fallacious assumptions; just forget about the openings and spend all that time on the endings.

There was a time in my life when I almost thought I could never lose a single duel of chess.

Chess is something more than a game. It is an intellectual diversion which has certain artistic qualities and many scientific elements.

In order to improve your game you must study the endgame before everything else; for, whereas the endings can be studied and mastered by themselves, the middlegame and the opening must be studied in relation to the endgame.

Chess is more than a game or a mental training. It is a distinct attainment. I have always regarded the playing of chess and the accomplishment of a good game as an art, and something to be admired no less than an artist's canvas or the product of a sculptor's chisel. Chess is a mental diversion rather than a game. It is both artistic and scientific.

When you sit down to play a game you should think only about the position, but not about the opponent. Whether chess is regarded as a science, or an art, or a sport, all the same psychology bears no relation to it and only stands in the way of real chess.
