Reading greens well is as important as the putter fit, stroke, or anything else “including confidence”

Everything from type of turf, slopes, moisture, time of day, sunlight and grain, drainage etc. but I’d say most amateurs overlook the influence of the wind… I always ask my students to identify where the rains and irrigation water will runoff the green. Where the water flows, the golf ball will tend to follow. To keep things simple. Water drainage and wind direction are my first observations.
