Grip it Right.

The primary fundamental in the game is how you grip the club. The grip is your only link between you and the club and it needs to be balanced to work properly. What I mean by balanced is that when you grip the club you should be able to hinge your wrist freely above your shoulders and not have the grip turn in your hands.

The best way to achieve a balanced grip is to lay the club shaft on your shoulder, letting the club head rotate downward into its balanced position. Then grasp the grip in your fingers with the thumbs aligned down the shaft and unhinge your wrists so that the club is now in front of you with the toe of the club pointing towards the sky. You may have to adjust the club slightly to achieve complete balance and comfort. Now swing the club or waggle it around. You shouldn't feel any twisting of the shaft, if you do, you need to re-grip and feel a new balance position.

Excessive grip pressure at the start of the swing is the number one cause for poor golf shots. You must have a firm but not a "squeezing" grip pressure at the start every stroke.  The analogy I like best for grip pressure at the start of the swing is to imagine that you are grasping a tube of toothpaste while trying not to squeeze any out of the tube. That would be, firm but not squeezing. At the top of your back swing you will unconsciously squeeze the grip naturally depending on the shot and then swing the club to the target.

I have seen many different grips that are effective which square the club at impact and there doesn't seem to be any single one that is the best. The best grip for you is the grip which is most comfortable and allows you to square the clubface. Try them all until you find the grip that suits you best and provides control and consistent results.
