TopSpin and BackSpin

I need some serious help learning to put in topspin. How do you add topsspin, and what are some situations when it might be useful?

Same for BackSpin. Thanks.

The way u can produce spin top or slice and side spin is learing to change your grip when playing. To create top spin use more of a semi to full western grip( meaing your plam is facing the sky and nuggles are point to the ground) and to get a slice you have a easter grip( your nuggels are facing up to the sky when hitting the ball at a angle with wrist bent pointing out. I hope this helps . Easier to show you than explain.

Here are some links that might be helpful. :)
