The probable method of prolonging a hit at backgammon, affords a case of instruction as well as curiosity; for there is a probability of making the hit last by one of the players for many hours, although they shall both play as fast as usual. Suppose B to have borne thirteen men, and that A has his fifteen men in B’s tables, viz. three men upon his size point, as many upon his cinque, quatre, and trois points, two upon his deuce point, and one upon his ace point. A in this situation can prolong it by bringing his fifteen men home, always securing six close points till B has entered his two men, and brought them upon any certain point; as soon as B has gained that point A will open an ace, deuce, or trois point, or all of them, which done, B hits one of them, and A taking care to have two or three men in B’s tables, is ready to hit that man, and also he being certain of taking up the other man, has it in his power to prolong the hit almost to any length, provided he takes care not to open such points as two fours, two fives, or two sixes, but always to open the ace, deuce, or trois points, for B to hit him. We add the following two critical cases for a back game. First, suppose the fore game to be played by A, and that all his men are placed as usual, B has fourteen of his men placed upon his adversary’s ace point, and one man upon his adversary’s deuce point, and B is to throw who has the best of the hit; answer, A has the best of it, gold to silver, because, if B does not throw an ace to take his adversary’s deuce point, which is twenty-five to eleven against him, A will take up B’s men in his tables either singly or make points, and then if B secures either A’s deuce or trois point, A will put as many men down as possible, in order to hit and thereby get a back game. It is evident that the back game is powerful, consequently, whoever practises it must become a greater proficient at the game than he could by any other means. Second, Suppose A to have five men placed upon his size point, as many upon his quatre point, and the same number upon his deuce point, all in his own tables. At the same time let us suppose B to have three men placed upon A’s ace point, as many upon A’s trois point, and the same number upon A’s cinque point, in his own tables, and three men placed as usual out of his tables, who has the best of the hit? Answer—The game is equal till B has gained his cinque and quatre points in his own tables, which, if he can effect, and by playing two men from A’s cinque point, in order to force his adversary to blot by throwing a cane, which should B hit, he will have the best of the hit.—_Strutt_—_Ency.
