For low running chips, imagine you are putting. A 'swing' back and through.
For pitching, imagine you are tossing a ball underhanded.
Chances are very high that you are adding lag pressure/jabbing at the shot, and you may also have too much shaft lean.
A nice trick of Alex Morrison's, hum 'rockabye baby' as you swing back and through.
Exactly what I was thinking. Running chips with a mid iron being like a putt. Maybe jabbing..................with throwaway....... "Over acceleration the menace that stocks all Lag and Drag". Happens to the best.
Check out Chapter 12, the Basic Motion Curriculum. This is key. The components are dependent on whether you are swinging or hitting. No wrist cock or pivot etc. Check the book.
