In 2-J-1, it states " Angled Hinging gives the Clubface a Slice producing uncentered motion so while the Clubface does 'Close' during impact, Clubface alignment is slightly 'Open' for short shots but for longer shots must be set up more and more 'Closed'"

Does that mean for say a driver the face should be closed to the impact plane line? Or since there is still some closing, it should be slightly open, but not as open as for horizontal hinging?

For Angled Hinging, the Clubface is aligned Closed to the Plane Line. In earlier editions of TGM, Homer advocated a Square alignment -- as opposed to Horizontal Hinging's Open alignment -- thinking that would be sufficient of offset the Fade characteristic. But he came to believe otherwise -- "the tendency to Fade is still there" -- and later advised the Closed condition referenced in 2-J-1.
