Tiger Wood's swing demo – Good swing thought keep the club shaft close to the right shoulder starting the down swing.

The backswing is where you lift the club from its starting position and bring it above your head. Try to rotate the torso on the backswing by shifting weight from the ball of your front foot to the ball of your back foot. Pay attention to the three distinct phases of the backswing:
Phase one: Move the hands straight back while keeping them close to your back leg. Try to keep your front arm straight while you do this. As the club head hinges backward, the shaft of the club becomes almost parallel to the ground.
Phase two: Continue a slight wrist break as you move your arm parallel to the ground. The club should be roughly perpendicular to your left arm (for right-handed golfers). The end of the club should be pointing slightly outside the golf ball.
Phase three: Rotate your torso back even further so that the club head travels slightly behind your hands at the top of the backswing. Your front arm should bend slightly during the last phase of the backswing.

Swinging down, “haul” the head of the club so that it lags behind everything else, and allow the 90 degree forearm/shaft angle to increase, then unwind rapidly through the impact area. This creates tremendous club head speed while allowing the body to move relatively slowly and maintain control.
Right before impact, try to lock your front arm again so that it's completely straight again, just how it was when you started your backswing.
Shift your weight from the ball of your back foot to the ball of your front foot. Allow your knees to move toward your target. Try to keep your front knee flexed, especially if you're hitting a driver.

Make sure to have the shaft leaning forward toward the target at the moment of impact. This will help to have the face of the club face square at impact, an important factor in directional control. Don't forget to use your hips to swing energy into your shot; don't just rely on your hands to produce the power.
