Often we need a less extreme version of a thumb grip. I call it a backhand grip, because that’s the most common name. You could also call it a partial or moderate thumb grip.
Let’s start with a forehand grip. From here you get a full thumb grip by turning the racket about 90 degrees. A backhand grip is similar, but you only turn the racket about 45 degrees.
This is not an exact number, because you will need to adjust the angle, depending on the situation. But 45 degrees is a useful starting point.
It’s important that the thumb pad is still placed on the wide bevel. It should not be placed on the diagonal bevel (that would be a bevel grip instead).
As always, the grip should be relaxed and cradled lightly in the fingers. It should not be held tightly in the palm.
