It is good to use the sidespin to get the ball out wide away from your opponent. It also adds a degree of difficult to return it for your opponent.
Remember though that it does make your own stroke less reliable.
To return a sidespin you need to adjust the angle of your bat to allow for the sidespin. So for a block, use a normal strokes but turn your bat a little sideways to counter the sidespin.
