Let's face it... many times on the court, you're stuck reacting to every move your opponent makes and you get caught at their mercy if you make the slightest mistake.
What if you were able to turn the tables on them by knowing exactly what type of shots they were going to make and where they were going to place the ball... wouldn't you gain the upper hand?
How much more fun would you have on the court if you could recognize common patterns in their movements and racket position and be instantly prepared for what's coming your way...
