The circle runner moves without the ball from the middle to the side and puts a barrier on the defending corner player.
The attacking corner player has the ball at that moment and can make use of the obstruction.
Or pass the ball to the set-up player
Who then passes the ball on to the half-career player and so on
The attacking corner player who passed the ball on to the attacker "runs with the ball" inside the 9m, slowing down a little.
He or she then comes between defender 2 and 3 towards the goal again and may receive the ball from the up-and-comer who has already received it at that point.
