Had a lesson with video. Aside from my "too much backswing" and no extension of my left arm, I was told I had too weak of a grip. I was told to strengthen my grip. The instructor drew to circles on my left hand's two knuckles. It did help, yet now my shots go left, him telling me that I am closing the face at impact to make up for my weak grip, I understand that because I am not used to it, the grip is uncomfortable. Yet I can barely see my first knuckle, and I can not grip the club to see both knuckles. Is this normal? I've read on this site about strong grips seeing not only 2 knuckles, yet 3???? Could this be my gip size? And what can I practice to stop me from closing the club face?
