First cutter (red) runs closely down his stack
As he plants and turns, the disc is released. simultaneously, the next player from the opposite stack starts his run.
As he stops and turns, the disc is released to him. The next cutter would then start his cut. the thrower would then recycle to the back of the stack
As the next player stops and turns, he will receive the disc. and the process is repeated.
