Yo, we are going to find out who the best tennis players of A-Eskwadraat are. Find a tennis buddy and enter, because we will be doing doubles matches. We will take care of the equipment, so it doesn't matter if you don't have any tennis tools.
The only thing you have to bring is a pair of tennis shoes with which you can graciously slide from the left to the right on artificial turf (no shoes with studs or the like).
