clubface rotation

I was watching some video on tiger and chuck and trying to notice the main similarities. one thing that i did notice is that they both seem to open the clubface open during the takeaway and backswing. I havent seen any of that discussed in the RST videos or in forum topics. what is the significance of this move and how is it best accomplished?

So can u explain why my cluface seems to be a little closed when I perform shoulder rotation with no hand manipulation during my takeaway. But chuck and tigers clubface seems
to be more square or even slightly open?

IMO, in the takeaway, there is no manipulation of the arms, hands, or clubface at all. Just a rotation of the upper torso. There is a small amount of natural rotation in the second half of the backswing when the right arm bends and moves to the right side of in front of the body.

I just watched the takeaway video again.  The reason this is important is that it is a sign that my takeaway and shoulder glide may be too flat or too vertical.  As I understand the video, the square to the arc clubface position is OK and even desirable if it doesn't interfere with the flow of the swing.  The video does reference the lawn mower move which we know is not an RST move. The square to the arc position helps me to get more width before bending my right arm and also to get my left shoulder to go down in the backswing.  Just doing the right shoulder blade glide does not by itself help me to get my left shoulder down. The rotation of the clubface to face up tends to lift my left shoulder up too much.  Am I just doing it wrong or is this a legimate concern?
