Try this for a great new aspect of the game of tennis. Play only half of the court width that includes the doubles alley. Serve as normal, return cross-court only and play only cross-court. This is a superb way to practice your doubles skills while playing with only one partner. The main idea is serve and volley only, though for less skilled players it is possible to play without that requirement.
