Federer Forehand
Set up position is with the right foot behind and outside the front left footwith the hips and shoulders rotated so that your opponent has a good view of the back of your left shoulder. Your feet should be approximately at a 45 degree angle to the net.
Djokovic Backhand
If you're a one-hander, you want your set up position to allow you to make contact with the ball with your arm in a comfortably bent (at the elbow) position. That is, on contact with the ball, you don't want your arm to be too bent at the elbow, or too straight.
For double handers, the right elbow generally remains more bent than for a one handed shot. At all costs, try to avoid hitting the shot with a straight front arm.
Nadal Slice
The swing itself should be very smooth, keeping the racket head above the wrist all the way through the shot. Don't try and generate pace by using lots of arm speed. Generate your pace with the timing of the shot. You should be leaning into the ball and hitting through the shot. Keep the wrist locked at all times, and keep the hand high in the follow through; i.e., don't let the hand relax and fall away with a subsequent drop in the racket head. At all times, attempt to keep your arm, wrist, hand and racket in line with one another.
Service and smash
You can hit the ball into the correct service square underarm if you want and it is a legal stroke. Your feet must be behind the baseline on the correct side of the court. If your feet touch the baseline or the centre mark it will be a foot fault. See court lines for further explanation. The serve is another stroke that has changed a lot in the last 20 years. Then, a player's first serve would be equivalent to the power of a player's second serve today.
Also the purpose of the serve has changed. It used to be just to get the first point before running in to the net and playing a volley.
