If your opponent is serving to you, are u allowed to stand anywhere on the court to receive the serve? Or if ur opponent is serving to you, do u have to stand behind the service line to receive the serve? My friend told me it is illegal to move across the service line as a receiver if the server has not made contact with the bird yet in a serve. When someone serves to me, I often charge forward to hit the birdy. My friend tells me that when he serves to me, I start charging forward before his birdy even makes contact with his racket, and this is illegal?
