Even numbers behind 4 stations at a 5 x 10m rectangle- use centre third to mark two sides.
(A) passes across the width of the rectangle to (B) who has performed a central lead and dodge
(C & D) both lead towards their respective sideline, however (B) chooses (C) to pass to.
(C) passes across the width of the rectangle to (D) who has made a second lead, this time back inside.
(A & B) both lead towards their respective sidelines, however (D) chooses (A) to pass to.
Effectively, the ball moves around the square via (A - B - C - D) with passes, however (B & D) must lead twice to receive their pass.
