Penhold Backspin vs Shakehand Topspin

Hi Alois

If there is a good backspinner-penholder play backspin vs topspin against a good topspinner-shakehander, who will have a better chance to win the point?

And i have tried your suggestion to fight against a player with good defence and control by top spin so i have more margin over the net, but i doesn't really good at topspin, i just can make a topspin if the ball is slow or "hitting the foeehand from below the table level", so i counter it by backspin (my favourite spin)

Thank you so much!

I will wait for your reply
