This week, we begin a 7-part series based on the book Instinct Putting Revisited by Dr. Bob Christina, Dr. Cary Heath, and PGA Master Professional Eric Alpenfels. Instinct Putting is based on the idea that visual input is stronger than memory. When you look at the hole, there’s a visual link between what you see and what you want to do. When you look down at the ball, you break that link.
