Hey ping pong players around the world, in this table tennis video, you can see Dandan doing a forehand topspin attack and me blocking his topspin drive. He actually did about a total of 6 topspin, 4 forehand topspin and 2 backhand topspin. So you can block a forehand topspin by just placing your ping pong paddle just at the end of the table about 4 inches high and at a 35 degrees angle. The more topspin attack he will hit the more the table tennis ball fly higher that is why you have to lower down the angle of your racket.
