19. PLACING BALLS FOR A CROQUET STROKE

1. BALL PLACEMENT Subject to Law 19(d), in preparation for a croquet stroke, the striker must place the striker's ball on the ground in contact with the roqueted ball however he chooses but not in contact with any other ball. Subject to Law 19(b), no other ball may be moved.
2. CANNONS If, after any necessary application of Law 12, the roqueted ball forms part of a group of balls, or would do so if the striker's ball was placed in accordance with Law 19(a), the croquet stroke is known as a cannon. In preparation for the stroke, all balls other than the roqueted ball become balls in hand and are temporarily removed. The roqueted ball must be replaced in its original position if it has been moved and the other balls are then placed as follows:
   1. 3-BALL CANNON The striker must place the striker's ball and the third ball on the ground in contact with the roqueted ball however he chooses provided that the striker's ball is not in contact with the third ball.
   2. 4-BALL CANNON The striker must place the striker's ball and one of the remaining balls as in Law 19(b)(1) and must then place the fourth ball on the ground not in contact with the striker's ball but in contact with one or both of the other two balls.
   The striker remains entitled to reposition the balls.
3. ELECTION OF BALLS If the striker moves a ball or balls in preparation for a croquet stroke, no election of the roqueted ball or, unless Law 9(b)(1) applies, the striker's ball is thereby made until the stroke is played.
4. FIRST STROKE OF A TURN In respect of the first stroke of a turn, the references in Laws 19(a) and 19(b) to the striker's ball shall include any ball of the striker's side which was in play at the end of the preceding turn and the references to the roqueted ball shall include any ball from which croquet may lawfully be taken.
5. CHANGE OF DECISION The striker remains entitled to reposition balls under Laws 19(a) or 19(b) until he plays a stroke.
