I was under the impression that KNN may be a forced win in some circumstances,
but usually isn't due to the knight's inability to make a waitng move like a
bishop (i.e. if a knight moves, it must go to a square of the opposite color,
but this may not be desired). Did a program find a way to force a win with KNN
or was Nouveau just partially mistaken? KNB and KBB allow forced wins. :-)
