Hit the ball flat or with topspin

Hi Alois,

When I should hit the ball flat ? and when should I hit the ball with top spin?

Can u give some tips, so I didn't miss a good opportunity to score a point?

Hi Ernest,

If the ball is below shoulder height then definitely play with topspin.  If the ball in higher than that and you are in a good position, then you can think about hitting it flatter with a smash.
