410 POLISH DRAUGHTS.
be laid for you in these twenty coups, and that is not difficult, as the player who has the three queens, has only seven coups by which he can win, and he has scarcely time to arrange them within the prescribed number of coups.
If the player who has only one queen occupies the diagonal line which extends from 5 to 46, to draw the game he has only to move constantly from one extremity of this line to the other, unless he should perceive that his adversary is preparing the only coup by which he can win the game—it is as follows :—
The white queen is upon 46 ; the three black queens upon 13, 16, and 27.
If the white queen who has the move went to the opposite extremity of the line or upon the squares 10 or 14, it is evident she would lose the game, because the adversary, by sacrificing two of his queens, would capture her afterwards; but nothing is more easy than to avoid this or a similar coup, it is only requisite to take up a position below the coup of the two on whichever side it may be arranged; for this purpose the white queen has four squares, 41, 37, 28, 23 ; this will serve as a guide in any other position. But when the central line is occupied by the player who has the three queens, the affair is different; there are then seven different kind of coups by which he may win the game.
First coup.—The three white queens occupy the squares 46, 37, and 27, and the black queen 11.
White sacrifice two at 22 and wins the game; the same ambuscade may be laid on several sides, but it is so apparent that it is seldom tried.
Second coup.—The three white are on the squares 19, 27, and 37, and the black at 11.
White sacrifices two at 22, and black loses on
