The players are placed as shown on the drawing.
At the same moment the coach throws a ball to the goalkeeper, the wing runs as fast as possible towards the opposite goal.
When the goalkeeper catches the ball the 2 other players runs forward while keeping an eye with the goalkeeper.
The goalkeeper passes immediately the ball to one of those 2 players.
After 1-2 passes the wing should have reached the opposite goal circle - ready to receive a pass from either wing or backcourt player - turn around and shoot at goal.

In a game situation it is important that the fast wing takes a position at the opposite goalcircle in such a way, that a pass can be made between the returning defenders.
