**Backwards is better: the circumbinary stable zone is larger for retrograde orbits**

Around a test binary star system, even in the generalised case where the two stars have eccentric orbits and unequal masses, stable retrograde circumbinary planet orbits are shown to be possible remarkably close to the two stars. With online simulations.
