Next year the “old” double rule will be back!
That means that there will be always one player of a team who will be the “attack player” and one will be the “serving player”. So, every time before one of a player of his team begins to serve both players status must be changed (every 6 points, from 15:15 every 2 points).
Further that means that just in the moment when the serving player is hitting the speeder with his racket to serve or to play the speeder back, the foot of the attack player must be before the foot of his partner and vice versa.
E. g., if the attack player will return a speeder and the serving players foot isnt behind him, the opposing team will get a point!
