I missed this part and can't seem to find it with a simple search. Would you mind posting a link? I'm using these shots from time to time, but still don't have enough consistency. Could revisit the thread a little.
I’m not sure it’s somewhere in a single post, more of multiple discussions.
The idea is that you move towards the ball (from wider away) to hit draw, and your arm gets launched “through” the contact point at an angle; and you shift away from the ball for fade shot, pulling your arm across the ball.
Also the degree of wrist release or keeping it lagged is in the mix to achieve desired outcome in most natural way.
This gets very interesting application when hitting higher and lower balls, for example, whether you drive up (which is “away” from low ball) or stay low and “flow through the shot” — on lower balls. And whether you shift away in open stance on higher balls vs driving up and into the ball…
Hopefully you can get automated execution and intuitively apply optimal choices once trained and ingrained, but being aware of this stuff during long-term development allowed for some great improvements, for example, since that 2022 video I posted above.
