you might be wondering what a "tennis point by point let's play" is! the idea of the game is to type out a tennis point like a story. here is an example.
it's 0-0, the first point in the Australian Open. Novak Djokovic starts off the point with a huge serve to Federer's backhand. Federer dumps the ball into the net.
then the next poster will come in:
15-0, with Djoker up. He misses the first serve and hits a kicker into Federers backhand, and the return goes crosscourt for a winner.
