As you come into the impact zone (as a right hander) your right wrist should be bent backwards and should remain there through impact. Amateurs tend to feel the need to straighten their right wrist and hit the ball with their right hand by flipping the wrist. They are probably not even be aware they are doing this.
It is essential to regard the hands as a unit when playing golf. Their role is largely passive through the impact zone. The power comes from an efficient swing and swing mechanics, not from manipulating the wrists through impact.
Your left wrist should be flat and your right bent back through impact which will necessitate your hands being well ahead of the ball through impact. All of these things are essential for correct club/ball contact.
Late release or uncocking of the wrists in the downswing will greatly aid in achieving the wrist positions outlined here. A helpful thought is to delay the ball contact as much as possible. Build the idea and feeling that everything is lagging behind your hands in the downswing. Believe me the club head will catch up no matter what you do and the later this happens the better. Try it and see.
