Wrist Action

[D10878]

For the longest time I have wanted to know how the left and right wrist should be maintained throughout the entire swing. I have let the left and right pretty much hinge on thier own with a nice strong grip though I have trouble squaring the face at impact. Should I try to maintain a shaking hand position throughout the swing as it is at address or should I let the wrists go with the natural turning. As I stated before the main issue is the open clubface at impact.

Thanks
