Keep chest and club head connected on longer wedge pitches
The main fault on the longer-club pitch is that, knowing there's a lot of club in hand, the chest slows down coming down and the hands work over, either closing the face or leaving it out to the right. The fix is to keep the chest bone and the club head staying in connection, connecting them up through the swing so the ball flies straight; this also works as a long-game drill.
