Open Green (no perils in front, i.e bunkers, waters, large rough, etc), and about 20 to 70 yards out? Use an eight iron!!

Choke down,place the ball 2 inches in front of your back heel, take a backswing like a putt, and swing. DO NOT BREAK YOUR WRISTS! Keep your head down.

Your backswing will determine the length the ball goes. As accurate as a putt, and much safer than lofting the ball. This is guaranteed to save you three strokes a round!
