When the server's score is odd, the serve is made from the left service court and received in the diagonal left service court. A fault committed by the player receiving results in a point for the serving player. During the serve the shuttle does not fall within the boundaries of the diagonal service court. During the serve the feet of the server and the receiver are not within the boundaries and on the floor of their respective service courts. Before or during the serve any player feints or balks the opponent.
Any player reaches across the net to contact the shuttle, other than on the follow-through.
During play any player's person, clothing, or racquet touches the net or supports. The shuttle is hit more than once in succession by a single player. The shuttle is caught or slung when struck. Rim shots and simultaneous striking of the base and feathers of the shuttle are legal if nor slinging or catching occurs. A player obstructs an opponent or invades the opponent's court.
