With irons, I have often hit the ball on the heel of the clubface and sometimes shank. I know the common cure is to stand with your weight evenly placed between the balls of your feet and the heels of your feet, or, to place more weight on your heels. I tried this and it kind of worked. Then, I stood further back from the ball and started contacting the ball in the center of the face, with no shanks.
Would standing too close also contribute to hooking the ball?
