If the service be delivered from the wrong court it is a
fault. It is also a fault if the server does not stand in the
manner as stated above, or if the ball served drop in the net or
beyond the service line, or if it drop out of court, or go in the
wrong court.
A fault must not be taken, that is, played back to the server.
The striker-out may not volley the service. Volleying is
striking the ball back before it has touched the ground.
The ball, having been returned, must be kept in play either by
volleying it, or striking it back after the first bounce. A ball
bouncing twice is out of play.
If, in serving, the ball touch the net and go over into the
proper court, it counts to neither server nor striker-out.
The server scores if the striker-out volley the service, or
fail to return the service in such a way that the ball would fall
within the opponents' court.
Two consecutive faults count a stroke against the server.
If the ball when in play touch either player it scores a stroke
for his opponent.
The first stroke won by either player scores 15 to that player;
the second, won by the same player, raises his score to 30, his
third stroke to 40, and his fourth counts game. If, however, the
players have both scored 40, it is called deuce, and the next
stroke won by either is called advantage to the winner of it, and
if he also win the following stroke he scorea game. Should he lose
it the score returns to deuce. The player winning two consecutive
strokes directly following a deuce scores game.
Whichever player first scores six games is considered to win
the set.
