5.3.3 Cadres of 47 cm and 71 cm with 2 strokes

Concerning the cadre of 47 cm one draws four lines which determine the following nine cadres on the billiard: three central rectangles within the length and six squares within the width. (paper C)
Concerning the cadre of 71 cm one draws three lines which determine the following six squares on the billiard: two central rectangles within the length and four squares within the width. (paper D)
As far as the cadre disciplines with two strokes are concerned the player does not have the right to execute succesively two cannons within the same cadre in the course of the serie without forcing at least one of the two object-balls to leave it by means of the second stroke.
