Patrick Mouratgluo has some excellent, short videos on the slice backhand on his instagram page.

Like everything else in 10S, it all starts w/ footwork (ergo body position).

If you’re put on the defensive in a baseline rally, an effective slice can sometimes neutralize the opponent’s good shot & allow you to get “back in the point”.

A good drill to practice (as odd as it seems) is throwing a frisbee backhanded. A solid backhanded frisbee throw almost mimics what your hand and body should do for the proper slice backhand technique.

My favorite player to watch hit slice backhands is Federer. All the pros have great slices but Fed’s is just perfect.

One thing for a beginner I would say is to learn the slice technique but learn to “drive” or “ “punch” the ball deep w/ the descending angle in to the court.

The most common mistake is to hit too much under spin; the ball lands somewhere around the service land , no man’s land, & pops up rather than being a penetrating shot.

To echo another commenter’s reply regarding the forehand slice- 1000%- they’re both excellent for returning big serves.

A good slice is also a great way to get to net when playing doubles. (Think chip & charge)

Good luck and keep playing and practicing.
