where does the serve have to land in tennis
Serve (tennis) For any serve, the server stands behind the baseline without touching it. For the first point of any game, the server stands to the right of the center point of the baseline and serves diagonally across the net to the left side (from the server's perspective) of the court, into the service box which extends to the service line about midway into the opponent's court. For the second point of the game, the serve is diagonally from the left to the right side of the court, and for each subsequent point of the same game the positioning is the opposite of that on the previous point.
Table tennis In game play, the player serving the ball commences a play.[35] The server first stands with the ball held on the open palm of the hand not carrying the paddle, called the freehand, and tosses the ball directly upward without spin, at least 16 cm (6.3 in) high.[36] The server strikes the ball with the racket on the ball's descent so that it touches first his court and then touches directly the receiver's court without touching the net assembly. In casual games, many players do not toss the ball upward; however, this is technically illegal and can give the serving player an unfair advantage.
