Grip length
When I showed you the basic grips, I was holding the racket towards the end of the handle. This is a long grip.
You can also use a short grip, where the hand moves up towards the cone.
Adjusting your grip for late forehands
The forehand grip works well for overhead forehands that are level with your body.
When the shuttle has travelled behind you, however, you need to shift towards a backhand or thumb grip.
Adjusting your grip for late backhands
The bevel grip works well for overhead backhands that are level with your body.
When the shuttle has travelled behind you, however, you need to shift towards a panhandle grip.
Adjusting your grip for a smash
In an ideal situation, the shuttle will be somewhat in front of you when you play a forehand smash.
In this case, it is natural to adjust the grip very slightly towards panhandle.
