We do not stop playing because we grow old, we grow old because we stop playing!

Games lubricate the body and mind.

The game of Chess is not merely an idle amusement; several very valuable qualities of the mind are to be acquired and strengthened by it, so as to become habits ready on all occasions, for life is a kind of chess.

You must not, when you have gained a victory, use any triumphing or insulting expressions, nor show too much of the pleasure you feel; but endeavour to console your adversary, and make him less dissatisfied with himself by every kind and civil expression that may be used with truth; such as, you understand the game better than I, but you are a little inattentive, or, you play too fast; or, you had the best of the game, but something happened to divert your thoughts, and that turned it in my favour.
