Here are a few videos that are particularly pertinent to my current swing issues and learnings:
Shoulder turn and how it affects swing plane / steep swing. Need to feel like my left shoulder is moving back behind the ball.
Chipping – everything moves together. Chips go wrong when it is just an arm swing. Turn back and turn through, the arms just go along for the ride. Pitching is exactly the same but you just add a bit of wrist hinge.
