"The first event in a causal chain can be important. I completely fail to
follow the "always" part. Perhaps you can find a hurricane that wouldn't
have formed if a particular butterfly hadn't flapped its wings, but not
every flap of a butterfly's wing causes a hurricane."

Please don't take my mention of the butterfly effect literally?
I am not seriously asserting that it (and anything similar) explains the
first-move-of-the-game advantage for white.  However, I am asserting that
the advantage for white in having the very first move in Chess carries all
the way thru the midgame and endgame to the last move of the game and is,
in fact, greater than virtually all Chess players have the complex
foresight to appreciate.  After all, Chess is a deterministic game of
perfect information.

You seem to want to argue with established facts and plausible attempts by
others to explain them.  Naysayers typically offer no or few ideas.
