I know there's 3 known types of spin, Topspin, Backspin, and side spin. Twist is a combination of sidespin and topspin. What do you call backspin with side spin (if that exists)? Also, what you do you call the spin when the ball rotates sideways on a horizontal axis? (what I mean by this is like drawing a 2D circle, that's the rotation of the ball) Also, how do you achieve the ball to go sideways rather than forward? I once hit a ball that bounced sideways towards the edge of the court rather than the ball moving towards my opponent's baseline (if the first statement was unclear). Thank you.
