When building the table base you have 2 states:  The position has been
solved or it hasn't.   The ones that haven't been solved yet are unknown.

This it is handy to  have 4 states:  Win, draw, loss, unknown.

My scheme is assuming all possible combinations of kings and pawns.  Some
of those might be illegal, i.e. kings adjacent or on the same square.  Therefor
some positions will never occur in a real game will always be "unknown."
