Raise the racket above the level of the ball on your back swing, and let the racket face open up at about a 45 degree angle. Also, turn your shoulders on your back swing. Then, come through the ball with a swift and sure motion, brushing downward so that the ball has under spin. The exact trajectory of the swing will vary with the height of the ball that has been hit. Your follow through should be an extension of your swing, and will end up lower than a normal backhand follow through.

When hit correctly, the ball should have a downward or flat trajectory as it goes over the net. It should skid a bit after its bounce, and stay low to the ground after its bounce. Both of these elements make it a difficult shout to return.

Another great thing about the slice backhand is that the preparation for a slice backhand and for a backhand lob varies very slightly. A slight change of motion and a flick of the wrist at the last moment can turn the slice into a lob and confound you opponents. But this only works if you have already demonstrated to your opponent that you can hit the slice.
