This is a viral video of some spectacular table tennis shots. It looks like an exhibition game but this is actually from a championship match between Waldner and Persson.
The most frequently asked question has been:
“Why does’t he just tap it in?”
According to the video uploader, it can not be done because of the massive spin of the defensive player. It is necessary for the offensive player (the player who continuously smashing the ball) to put a forward spin to counteract the unpredictable defensive spin.
Suppose the offensive player just tap it, the ball will bounce high and could be set up for a smash by the defensive player.
