There is an old saying in golf instruction: “You have to give up control to gain control.”
From a golf mechanics standpoint, it means that if your grip pressure is light and your arms are relaxed, the club will move more naturally and the golf ball will respond more favorably than if you had more tension in your body.
Most golfers ignore this idea and squeeze the club very tightly, with lots of forearm tension, and impose their own will on the club in an attempt to make it move a certain way. And more often than not, it’s the wrong way. If you just setup and let everything hang relaxed, the club face will naturally swing open going back find its way back to square at impact.
