II. Circumspection, which surveys the whole chess-board, or scene of action, the relations of the several pieces and situations, the dangers they are respectively exposed to, the several possibilities of their aiding each other, the probabilities that the adversary may take this or that move, and attack this or the other piece, and what different means can be used to avoid his stroke, or turn its consequences against him.
III. Caution, not to make our moves too hastily. This habit is best acquired by observing strictly the laws of the game, such as, "If you touch a piece, you must move it somewhere: if you set it down, you must let it stand:" and it is therefore best that these rules should be observed, as the game thereby becomes more the image of human life, and particularly of war; in which, if you have incautiously put yourself into a bad and dangerous position, you cannot obtain your enemy's leave to withdraw your troops, and place them more securely, but you must abide all the consequences of your rashness.
And, lastly, we learn by chess the habit of not being discouraged by present bad appearances in the state of our affairs, the habit of hoping for a favourable change, and that of persevering in the search of resources. The game is so full of events, there is such a variety of turns in it, the fortune of it is so subject to sudden vicissitudes, and one so frequently, after long contemplation, discovers the means of extricating oneself from a supposed insurmountable difficulty, that one is encouraged to continue the contest to the last, in hopes of victory by our own skill, or at least of getting a stale mate, by the negligence of our adversary. And whoever considers, what in chess he often sees instances of, that particular pieces of success are apt to produce presumption, and its consequent inattention, by which the loss may be recovered, will learn not to be too much discouraged by the present success of his adversary, nor to despair of final good fortune upon every little check he receives in the pursuit of it.
That we may, therefore, be induced more frequently to choose this beneficial amusement, in preference to others, which are not attended with the same advantages, every circumstance which may increase the pleasures of it should be regarded; and every action or word that is unfair, disrespectful, or that in any way may give uneasiness, should be avoided, as contrary to the immediate intention of both the players, which is to pass the time agreeably.
Therefore, first, if it is agreed, to play according to the strict 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 indulgencies, 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 difficulty, or to gain an advantage. There can be no pleasure in playing with a person once detected in such unfair practice.
Fourthly, if your adversary is long in playing you ought not to hurry him, or 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 endeavour 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 endeavour 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 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."
