2 players stand ready on each side of the center line.
On a signal both players runs forward and the coach throws a ball to the player most far away.
This player must catch the ball, run against goal and shoot.
The other player must try to catch the ball or - legally - prevent a shot at goal.
If the defender catches the long throw, a counter attack against the throwing goal keeper is made, and the former attacker must try to prevent this - legally.
