Initially I was tempted to call a draw game in any VonNeumann game as a
gravity attractor such as gravity equilibrium or gravitational center so that
if you introduce a "draw game inside of Nim" that the OS of Nim shifts and
then becomes something different from its automatic win for second player.
That the moment you introduce a possible draw game that the entire OS of Nim
shifts and becomes that draw end result.
But there is another concept in physics that is like gravitational
attraction. And I suppose a "good physicist" not the usual run of the mill
sort can tell you the conceptual difference between gravity attraction and
Great Attractor in chaos theory.
I like to think of Great Attractors in EM of electricity and magnetism.
Anyway, Nim is VonNeumann gametheory and the OS is a certain victory for
second player. But introduce just one possibility of a draw outcome, then,
does the entire OS of this Nim change to the draw outcome? As like a Great
Attractor, the draw outcome forces itself as the Optimal Strategy.
