Turn the lead hand to three knuckles for forward shaft lean
Craig Hanson describes an easier grip change to encourage forward shaft lean: turn the lead hand in until you see three knuckles so the lead wrist starts more into extension. From there you can still reach a flat lead wrist at the top, which sets the sole of the club slightly higher than the lead forearm and makes you hang onto your angles into impact.
