"Hitting" is about "maximizing the shaft bent" (or "lag") through impact by pushing the grip (against the inertia of the clubhead and ball) with both arms and hands, which can be achieved with the help of "unbending the right wrist", along with "straightening the right arm" and "rotating (and/or sliding) the pivot".

Try it to see it!!

Unbending = Flattening
"Unbending the right wrist" = Flattening the right wrist = Bending the Left Wrist = Instant Throwaway.
