smash, topspin or both

hi Alois and Jeff. sometimes when i hit the ball hard with a bit of topspin and i noticed that some peoples smashes are a bit more powerful and i was wondering if i should stick with the smashes that have a bit of topspin or i should practice hitting the ball flat

thank you in advance

Hi Bjarki,

To get real power with your smashes, you should hit the ball very flat.  The topspin slows the ball down a little.

If you want to play a safer stroke you can use a little topspin but if it is speed you are looking for, go for the flat smash.
