When hitting a shot from a greenside bunker, a very effective swing thought is to hit some sand out onto the green.  If you're not getting enough sand, square the club face and swing at a steeper angle.  If you're getting too much sand, open the club face and swing at a more shallow angle.

At address:  Ball position just inside left heel	Club face is open so it slides under the ball

Swing with enough force as if to hit a  50-75 yard shot, about a 3/4 swing	Long shallow divot... think bacon strips not pork chops
