These lines along with the service line, side wall, and short line forms the doubles box wherein the doubles partner that is not in serving position stands during the actual serve. The other set of lines is 36 inches from the side wall. These lines combine with the service and short lines in order to mark an area that the server must not enter if he intends to make a drive serve between himself and the nearest side wall. The lob variations of the defensive serve are utilized in order to place the opponent in situations that would render him unable to set up an effective return. The plain lob serve provides the other player with very little area to work out a good solid response. A junk lob is performed in order to situate the landing of the ball close to the side wall in between the dotted line and back wall. If you do your pinch shot too high, the ball will bounce once from the front wall and sets up your opponent for his own kill shot. On the reverse, hit the ball at the other side wall about 2 feet (or less) and within 1 to 2 feet from the front wall. The ball will bounce twice because it hits the front wall low. Due to the competitive nature of the sport there are times when each player battle for positioning. This can then lead to one participant hindering the other s chance to hit the ball. In such cases hinders or penalty hinders can be called. Hinder is defined as the repetition of the present rally. On the other hand, a penalty hinder is marked by a player s effort to not execute an avoidable obstruction which leads to the stoppage of a rally.
