In learning to control the clubface you learn to monitor your hands. If your hands are on the club properly, and when you strike the ball your hands are leading and the left wrist is flat and the right wrist is slightly bent back and that shaft is leaning slightly forward, you will have a square clubface. Now that would be simple to achieve if we held the clubface, and if you really want to know that is exactly what we are doing. We are holding the clubface by holding the grip, and all I have to do is monitor my hands so that my hands are at this position at impact. That happens very fast, and remember when you hit a full shot you are not swinging to impact you are swinging to the finish. The best place to monitor it is on little short chip and run shots where you can actually finish a couple of feet past the ball and check to see if your hands are in the proper position. Let me hit a shot to show you how I would monitor it. In a chip and run shot I would want to make sure that the club was still in line with my left arm at the point a couple of feet past impact. Obviously in a full swing it would pass through that point just mentioned and keep going around my body through to the finish. You are actually trying to drive the golf ball into the air. You are not trying to lift it; you are trying to squash it with a nice square clubface into the air using the loft of the club. Never try to lift it in the air. Learn to control the clubface by monitoring the hands. A flat left wrist at impact gives you a good square clubface if you start with the correct grip.
