Scoring is a kind of vision--a way of seeing the variety of shots you can hit in a given situation. And I know from firsthand experience it's a vision you can learn. On and around the greens, develop the ability to "see" the options tour players see, and pick the one that matches your skill, confidence level and risk tolerance. Then understand the mechanics of how to hit it. You have more choices than you think: For example, the basic bunker shot I'm hitting above works just as well from grass as a lob. On the next three pages, I'll demonstrate a short-game shot and give a strategy tip for each level of player.
GET IT OUT: In the sand(above), start with your hands back. Keep your weight left, and swing the clubhead end, not the grip end, fast.
