Backhand Slice for 2hbh

[arun_mrk]

I play 2 hbh but hardly learned/played a backhand slice.
I usually play 1 hand backhand slice only when the ball is short and i had to stretch to reach for the ball.

I have seen people doing a backhand slice on high balls for returning serve.. Any instruction on how to do this?!!
Also, in general please give me some tips on how to do a deep slice on a backhand

In this Wilson racquet commercial from 1973, Billie Jean King demonstrates perfect high backhand slice technique. The same pronation/supination motion that BJK uses in this shot can be used on all slice backhands for more power. It is a very short view and doesn't show the takeback or the finish. But, the important part - the pronation/supination motion, can clearly be seen.
