The server must stand behind the service line with both feet. The ball must bounce once and then then ball is served into the reception area of the opposite side with a half volley.
The service may also be done by bouncing the ball on the side wall.
BALL IN PLAY:
Once the service is delivered, the ball is in play and will remain in play until the end of the point.
The players then have a minimum of two and a maximum of three touches to return the ball to the opponent's side.
In this zone, players are allowed to return the ball on the first touch without playing with their partner.
