Recreational tennis players instinctively make these 10 shot errors when they start playing tennis. Initially, they may work because their competition is also new, but as their competition gets better, they will not work well and will limit their success on the court. They often hit a plateau. Even though they play for years, their tennis game doesn't really improve; they have "on" days and "off" days.

Many players fail to realize they are hitting the wrong shot, at the wrong time and to the wrong target. And watching professional tennis players is NOT a solution; they have advanced skills which, if emulated, will cause many errors.

The SOLUTION is presented; the top 10 SINS and how to correct them by understanding the STRATEGY of tennis doubles. Of course practice helps but many of these are "aha's", an instant understanding of, "I've been aiming at the wrong target."
