Release your right hand

It has been said that if you slice the ball it is because your right hand hasn't come through. Not true

What you have to do is complete your back swing, get your left side (starting with your hips) leading on your downswing, everything else will follow, shoulders, arms and hands. Your right hand will release naturally at impact. If you consciously release your right hand early, you will smother the ball (club face shuts) and hit the ball fat.
