I SEE a lot of amateurs holding the club too tightly. I notice it most when they try to waggle. The movement looks stiff and short.
To swing correctly, the right amount of grip pressure—and where you apply it—is important. You should feel the club being supported by the last three fingers of your left hand (above, left). Those fingers should grip the firmest. My longtime teacher, the late Stan Thirsk, used to remind me to keep the club in the fingers of my left hand and never let it slip into the palm.
