Hi,
This is my first post at this forum, so maybe I should introduce myself a little bit: I'm an amateur golfer with a 10 handicap with a background in physics, but I'm by no means a golf swing biomechanics expert. I just would like to learn more about this topic.
After reading the impact chapter on your website, Jeff, I have a few questions about how grip strength influences the release:
Usually a weak left hand grip is expected to cause an open face at impact and thus slice spin, while a strong left hand grip is expected to cause a closed face at impact and thus hook spin.
But why is this? Does the left forearm always assume a "neutral" position when the 3rd power accumulator is released, so that a weak grip / more supinated forearm at address leads to a less supinated forearm at impact and therefore an open clubface? How about the influence of a weak/strong right hand grip?
Best regards,
Robin

I think that you have got it basically correct - many golfers rotate their left forearm counterclockwise pre-impact (irrespective of their left hand grip strength) and if they have a strong left hand grip, then they should not be performing that action because they will excessively close the clubface pre-impact. By contrast, a weak left hand grip needs the maximum amount of left forearm rotation pre-impact in order to square the clubface by impact, and any slight tendency to perform an incomplete release of PA#3 will result in an open clubface at impact.
A strong right hand grip can also result in a closed clubface at impact - if the golfer allows his right forearm to pronate during the right arm straightening action.
Golfers who use a strong left hand grip and a strong right hand grip must not allow their forearms to rotate counterclockwise between P6 and P7 if they want to have a square clubface (and not a closed clubface) at impact.
Jeff.
