Dave Stockton (putting genius) has a drill where he has his students place an object 2-4 inches in front of the the ball on a 3-10 ft putt and you concentrate on rolling the ball over that spot. Essentially, you turn a 3-10 ft putt into a 2-4 inch putt. Dave Stockton specializes in simplifying the putting game. Check out his website at www.davestockton.com or check out his iPhone app. Also, check out trulinegreens.com. They make great indoor putting greens that allow you to chip and putt. I thought I attempted 100 but only putted 80. I was listening to the Dan LeBatard radio show podcast and lost track.
