It's been a while. I'm a fair golfer of 4 Hcp and recently hit a bit of a phase where i 'putt from the rough' - no metaphor.
I had a short game lesson with a high end instructor who taught me to chip using bounce. Quickly in summary;
Weight 70% front foot,
Square Alignment, feet 4-5 inches apart,
Ball inside left heel,
Club face 1 degree open to utilise bounce,
Hands no more than 5degree forward shaft lean,
Stand more upright, Swing reasonably Square to square...
