I am a rooky to the golfing machine. I discovered 10-10-B today. I am a dentist and during slow days, I practice my chipping in the basement. I have a chipping net and golf mat. After reading 10-10-B in the Yellow Book, I tried the left hand palm up to low point and then palm down after low point. My gosh!!! The balls were shooting over the top of my 48 inch net. Never happened before. I can't wait to get outside and try it for real. Thanks Homer for this great insight!!!
