Thumbs-off drill to feel the clubhead and release
A drill to cure a tight, grippy chipping stroke: once you can trust your swing plane, hit some chip shots where you almost let your thumbs come off the grip as you start down. Taking the thumbs off lets the club start releasing and lets you feel the clubhead and its weight; the instructor also cues holding the club in the fingers with the thumbs barely on.
