As your pro has told you a thousand times, golf is a left-handed game. You grip the club with your left hand. The left hand takes the club back, leads it down into the ball and directs it forward into the follow through. The right hand must be kept out of the action. However, perverse as it may seem, putting is a right-handed business. It is the right hand that draws the club away, then leads it into the ball and through toward the cup. And so, instead of the normal interlocking or overlapping grips, which have only three right-hand fingers on the club, it is preferable that you use a reverse overlap for putting. This reversed grip has all four fingers of the right hand on the handle. The stroke is dominated by the right hand. The result—for right-handed golfers, at least—is a firmer grip, more feel of the stroke, more control and greater confidence.
