No more “digging”
When the clubhead is closed in the backswing (see picture 2), the sharp front edge of the clubface, “leading edge”, is likely to burst into the grass, making it very difficult to hit a good chip. This can be avoided by opening the clubface in the backswing
How is it checked?
Place yourself in front of a mirror or use your phone to record a video of your chip. Use picture 1 and picture 2 to compare with. The key is in the lead wrist (left wrist for a right-handed player). Study the 2 pictures closely and look at how this wrist is placed/shaped.
