How to play backhand topspin against a long ball

Hi Alois and Jeff,

Firstly all the table tennis lessons videos posted here are really good and I've learnt a lot from it. A hearty thanks for that.

Now I've started learning backhand topspin. I'm able to topspin the ball which is short. But I'm facing problems while doing backhand topspin, when the ball falls at the depth(end) of my table. Most of times either I don't feel like doing a top spin over it and will go for chop. Sometimes when I try doing a topspin over it, It generally goes over(out of) the table.
Do you have any suggestions/techniques to improve the same?

Hi Ananda,

Thanks for the kind words about our videos. It's nice to know we are helping people. :)

It's great that when the ball is not that deep you are able to play a good topspin. This means that with a bit of adjustment you should be able to cope with these long balls. It sounds to me that when the ball comes a bit longer you need to take a small step backwards. This will allow the ball to come more into your hitting zone and allow you to play a similar stroke as you do now for the ball which is not as long.
