Serving backhand to the outside corner in doubles when your receiving opponent is standing near the front service line may not be such a good idea, unless the opponent has poor footwork. The reason why is that this wide serve opens your formation, which is an attacking formation when you serve low, into a defensive formation as a push return to a spot to the side between the server and his partner will split your attacking formation. Why would you want to do that? Yes, you can use this wide serve as a variation but only against a player who is poor in returning such a serve. A good short backhand serve in doubles should not have a flat trajectory, which is common when you hit the shuttle sideways when serving. This is because a flat trajectory is easy to attack with a fast push. The flatter the serve the easier it is to push. However, if you serve backhand with the cork/base square to the racquet stringbed, then the serve will be less flat. It will rise up more, and if the serve is near perfect it will crest at the net and then drop sharply towards the receiver's front service line. This is the type of doubles serve that cannot be attacked or even pushed, irrespective of where the receiver stands, even if his racquet is almost touching the net.
