One of the players begins by serving. The selection of the court is usually chosen by lot or by tossing up a racket in a way similar to tossing a cent. The side of the racket where the woven gut appears is called “rough,” and the other side “smooth.” This practice is not to be recommended, as it injures the racket. It is better to toss a coin. The game of tennis consists in knocking the ball over the net and into the court of your opponent, keeping up this volley until one side or player fails to make the return properly or at all, which scores his opponent a point. While a game in tennis consists of four points, the simple numbers from one to four are not used. The points run 15,30, 40, game, when one side makes them all. Or it may be “15-30,” “15 all,” and so on, the score of the server being mentioned first. Where one side has nothing their score is called “love.” When one side has scored four points the game is won—with this exception: When both sides are tied at 40, or “deuce,” as it is called, the winners must make two points more than their opponents to win. In this way the game may be continued for a long time as the points are won first by one side and then by the other. The score at deuce, or “40 all,” will be denoted as “vantage in” or “vantage out,” depending upon whether the server’s side or the other wins one of the two points necessary to win from “deuce.” If first one side, then the other, obtains one of these points the score will be “vantage in” or “out,” as the case may be, and then “deuce” again, until finally when two points clear are made it is “game.” A set of tennis consists in winning six games, but in this case also there is a peculiar condition. Where each side wins five games it is necessary in order to win the set to obtain a lead of two games. The score in games is then denoted just as in a single game, “deuce” and “vantage” games being played until a majority of two is won.
