I. _Foresight_, which looks a little into futurity, considers the consequences that may attend an action: for it is continually occurring to the player, "If I move this piece, what will be the advantage of my new situation? What use can my adversary make of it to annoy me? What other moves can I make to support it, and to defend myself from his attacks?" II. _Circumspection_, which surveys the whole chessboard, or scene of action, the relations of the several pieces and situation, 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 your 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 favorable 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 one's self from a supposed insurmountable difficulty, that one is encouraged to continue the contest to the last, in hope of victory by our own skill, or at least of giving 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 pleasure 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.
