Iím trying to demonstrate that we can use pronation very efficiently to create clockwise sidespin. We also can use elbow flexion. But, tip of the racquet should be directed upward.
If we want counterclockwise sidespin the racquet tip should be directed down. I believe we already discussed this matter.
