Curious how many of you cock your wrist when chipping? I do and I see many guys on tour do so, esp for longer chips. Europeans do it a lot.
Chip Shots are the realm of the Arm Accumulators, i.e., Right Arm Drive (LinearMuscle Power / #1) or Left Arm Swing (AngularRadius Power / #4, usually with Pivot Transport). See 12-5-1.
Pitch Shots additionally involve the Hand Action Accumulators, i.e., Left Hand Turn and Roll (rotational Transfer Power / #3) and Left Wrist Cock and Uncock (perpendicular Velocity Power / #2). See 12-5-2.
Hitting or Swinging, longer Short Shots -- -- usually involve both Pivot Transport (of the Arms to Release) and Hand Action Transport (of the Club to Impact).
