Use a three-to-four knuckle grip to cure a slice
Craig Hanson recommends a stronger three-to-four knuckle grip, checked by looking down over the arm without moving the head much until you see three knuckles. He says this grip gives more movement in the wrist and joint, more power and speed, sets the club in a more aggressive position, makes it easier to hinge and break through the ball, and helps square the face around impact.
