Runner starts with the ball.
He looks up, makes eye contact, passes the ball to the wall player and makes a run to space. The wall player plays the ball back to the runner, first with two touch, then with one touch. Wall player must read the run. Wall player moves to a different position after he makes the pass Runner receives the ball back from the wall and pulls a coerver move. He then prepares himself to make a second pass and the sequence starts again.
