6. It is a _fault_ if the server fail to strike the ball, or if the ball served drop in the net, or beyond the service line, or out of court, or in the wrong court; or if the server do not stand as directed by law 4. 7. A ball falling on a line is regarded as falling in the court bounded by that line. 8. A fault cannot be taken. 9. After a fault the server shall serve again from the same court from which he served that fault, unless it was a fault because he served from the wrong court. 10. A fault cannot be claimed after the next service is delivered. 11. The server shall not serve till the striker-out is ready. If the latter attempt to return the service he shall be deemed ready. 12. A service or fault, delivered when the striker-out is not ready counts for nothing. 13. The service shall not be _volleyed_, _i.e._, taken, before it has touched the ground. 14. A ball is in play on leaving the server’s racket, except as provided for in law 6. 15. It is a good return, although the ball touch the net; but a service, otherwise good, which touches the net, shall count for nothing. 16. The server wins a stroke if the striker-out volley the service, or if he fail to return the service or the ball in play; or if he return the service or the ball in play so that it drops outside of his opponent’s court; or if he otherwise lose a stroke, as provided by law 18. 17. The striker-out wins a stroke if the server serve two consecutive faults; or if he fail to return the ball in play; or if he return the ball in play so that it drops outside of his opponent’s court; or if he otherwise lose a stroke as provided by law 18. 18. Either player loses a stroke if he return the service or the ball in play so that it touches a post of the net; or if the ball touch him or anything that he wears or carries, except his racket in the act of striking; or if he touch the ball with his racket more than once; or if he touch the net or any of its supports while the ball is in play; or if he volley the ball before it has passed the net. 19. In case any player is obstructed by any accident, the ball shall be considered a _let_. 20. On either player winning his first stroke, the score is called 15 for that player; on either player winning his second stroke, the score is called 30 for that player; on either player winning his third stroke, the score is called 40 for that player; and the fourth stroke won by either player is scored game for that player, except as below: If both players have won three strokes, the score is called _deuce_; and the next stroke won by either player is scored _advantage_ for that player. If the same player wins the next stroke, he wins the game; if he loses the next stroke the score returns to deuce; and so on, until one player wins the two strokes immediately following the score of deuce, when game is scored for that player.
