A good grip is the foundation of your golf swing, enabling greater control and reducing your tendency to slice. A good grip helps keep the club-head square at impact and stops the shaft from rotating in your hands.
The most popular grip used by professional golfers is the Vardon grip.
Place your little finger on the lower hand on the club (right hand for a right-handed player – known as the trailing hand) and place it between the index and middle finger on the top hand (known as the lead hand). The thumb of the lead-hand should fit in the lifeline of the trailing hand (the V). Look to get a relaxed and comfortable feel, a tight grip will hinder your swing. The V’s formed by the index finger and thumbs on both hands point between the chin and right shoulder. Turning hands anti-clockwise on the club shaft produces a weak grip, promoting a left-to-right flight of the ball (slice). Turning hands clockwise produces a strong grip, promoting a right-to-left flight of the ball (hook).
