The grip is the most precise and important part of the golf swing. It is the
only communication you have with the golf club and cannot be "half right".
Not all good players have good swings, but they all definitely have good grips.
The club head should be placed square to the target.
The club handle should be held in the left hand so that it is held in
the fingers and the palm. A "V" formed by the left thumb and left index
finger should be underneath the pad of the left hand so the wrists can hinge
properly on the back swing.
The right hand grip should be in the finger of the right hand, with the "V"
pointing toward the right shoulder.
The club should be firm enough to maintain control, yet soft enough to
feel the club head.
