The proper squash grip is very counter intuitive. Instinct would tell you to grip the racquet with a clenched fist. The racquet has no control in the fore aft and side side motion with that type of grip. The proper squash grip has two subtle features that allow you to have full control over the head of the racquet. It is extremely important to master this grip early on otherwise you will be stroking the ball incorrectly and find it very difficult to play the touch shots that pros play with ease. Furthermore your game will suffer for several months as you try and fix your grip after developing bad habits.
