Therefore, first, If it is agreed to play according to the strictest rules, then those rules are to be exactly observed by both parties, and should not be insisted on for one side, while deviated from by the other--for this is not equitable. Secondly, If it is agreed not to observe the rules exactly, but one party demands indulgences, he should, then, be as willing to allow them to the other. Thirdly, No false move should ever be made to extricate yourself out of a difficulty, or to gain an advantage. There can be no pleasure in playing with a person once detected in such unfair practices. Fourthly, If your adversary is long in playing, you ought not to hurry him, or to express any uneasiness at his delay. You should not sing, nor whistle, nor look at your watch, nor take up a book to read, nor make a tapping with your feet on the floor, or with your fingers on the table, nor do any thing that may disturb his attention. For all these things displease; and they do not show your skill in playing, but your craftiness or your rudeness. Fifthly, You ought not to endeavor to amuse and deceive your adversary, by pretending to have made bad moves, and saying that you have now lost the game, in order to make him secure and careless, and inattentive to your schemes; for this is fraud and deceit, not skill in the game. Sixthly, You must not, when you have gained a victory, use any triumphing or insulting expression, nor show too much pleasure; but endeavor to console your adversary, and make him less dissatisfied with himself, by every kind of civil expression that may be used with truth; such as, "You understand the game better then 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 favor." Seventhly, If you are a spectator while others play, observe the most perfect silence. For if you give advice, you offend both parties; him against whom you give it, because it may cause the loss of his game; and him in whose favor you gave it, because, though it be good, and he follows it, he loses the pleasure he might have had, if you had permitted him to think until it had occurred to himself. Even after a move, or moves, you must not, by replacing the pieces, show how it might have been placed better; for that displeases, and may occasion disputes and doubts about their true situation. All talking to the players lessens or diverts their attention, and is therefore unpleasing. Nor should you give the least hint to either party, by any kind of noise or motion. If you do, you are unworthy to be a spectator. If you have a mind to exercise or show your judgment, do it in playing your own game, when you have an opportunity, not in criticising, or meddling with, or counseling the play of others.
