face closed, but looks square at address

[jamnet]

I think you maybe on to something … my left wrist is ever so slightly cupped at address and when I check after the swing I try and return it to that slightly cupped address look. However, when I do pull hook it looks like my left wrist is over cupped.
Is the fix for this making sure I have a flat left wrist through impact, or is this related to something else?

Thanks
