Is the world "flat"?

Arch your Left Wrist at Impact Fix . . . Clubface will OPEN. So maybe some people HOOK who have the Arch at the Top because the have to compensate for the alignment at the top which looks "shut" but is really OPENNING the clubface.

One interesting thing that I picked up by watching Yoda give this guy a lesson was that he was a bit Arched and as a result couldn't fully uncock to Full-Lever Extension. As a result could get completely DOWN because his Left Arm Wedge couldn't work properly.

gotta love the Machine.

Arch your left wrist at impact fix...clubface will tend to open. Correct. Actually, the clubface will be slightly delofted as well as opened slightly. Now try this...

Take your normal grip and cock the left wrist so the club comes straight up and the club and left arm form a 90 degree angle. Hold the club in front of your chest, arms parallel to the ground, clubshaft pointing to the sky, clubface "square". This mimics the left arm - clubshaft relationship at the top of the swing (90 degrees). Now arch your left wrist. The clubface will close as the shaft is axially rotated into a closed position, exactly the opposite effect as arching the wrist had on the clubface while in the address/impact position.

I picked up this interesting tidbit from a famous instructor who knows TGM inside and out, and I haven't heard anyone talk about this since.

As the number 3 accumulator angle increases or decreases, the resulting effects on the clubface change dramatically in regards to bowing (arching) or cupping (bending) the left wrist.

So, at the top of the swing, assuming a 90 degree angle between clubshaft and left arm exists, bowing the wrist shuts the clubface due to the shaft being axially rotated closed.

More food for thought...

Ben Hogan...

Cupped at the top...has an opening effect on the clubface...AND bowed at impact...also has an opening effect on the clubface...a perfect formula for a left-to-right ballflight.

That's the secret right there. It's not just the cupped left wrist at the top. It's not just the bowed left wrist at impact..it is the combination of the two.
