3. If the striker, when in hand, plays from any position not within the six-inch radius.
4. If, in the act of striking, he has not at least one foot touching the floor.
5. If he strikes while a ball is in motion, unless it has come to a rest, as provided in Sec. 10 on Foul Strokes.
6. If he plays with the wrong ball, except as provided in foregoing Law 10.
7. If the player touches the cue-ball more than once in any way, or hinders or accelerates it in any other way than by a legitimate stroke of the cue; or if, during a stroke or after it, he in any way touches, hinders, or accelerates an object-ball, except by the one stroke of the cue-ball to which he is entitled.
8. As touching any ball in any way is a stroke, a second touch is a foul.
9. It is a foul against the striker if any ball be disturbed, hastened, or hindered by an opponent or any one but himself, whether the ball or balls are at rest while he is aiming or striking, in motion after he has struck, or at rest again after he has struck, and pending his again taking aim.
10. Should a ball that has once come to a standstill move without apparent cause, while the player is preparing to strike, it shall be replaced. Should it move before he can check his stroke, it, and all other balls set in motion by that stroke, shall be replaced, and the player shall repeat his shot, inasmuch as but for the moving of the ball, he might have counted where he missed, or missed where he counted.
11. It is a foul if the striker plays directly at any ball with which his own is in fixed contact, and the striker must in this instance play from balls spotted, as in the opening stroke of the game.
12. It is a foul to place marks of any kind upon the cloth or cushions as a guide to play; also foul to practise the banking shot for the lead-off upon the plea of testing the balls.
