A game of chess is not an examination of knowledge; it is a battle of nerves.

In the middlegame one should not hesitate to advance a central passed pawn.

Nowadays grandmasters no longer study their opponent's games so much, but they study his character, his behaviour and his temperament in the most thorough fashion.

Chess is imagination.

Independence of thought is a most valuable quality in a chess-player, both at the board and when preparing for a game.

Chess is infinite, and one has to make only one ill-considered move, and one's opponent's wildest dreams will become reality.

The essence of Chess is thinking about what Chess is.
