In some cases, you have to compensate your clubface in the golf swing. If you have the golf ball in the natural position, in the middle of the feet, you grip your club normal, but if you place the ball towards the front or back, you have to compensate te clubface in order to get the ball straight to the target. You place the ball towards the front if you want to have a hight ball flight and to the back if you want to let the ball fly low. Open or close the clubface slightly in these cases.
