That wasn't my definition.  When chess is solved, we will know, from the initial
position, whether white wins or loses or draws.  And for any white first move,
we will know the correct black first move to preserve the game status as defined
by white's first move.  Repeat forever.

IE the KRPKR ending is _solved_.  For every possible legal position, we know
whether white wins loses or draws, and we know the correct move to produce that
result...  That is solved...
