There was no intention to encode the bishops separately. It just
happens that the rules of chess allow one to distinguish the bishops
simply by recording the colour of the square they are currently on.
The basic text elements in the scheme other than boundary markers will
empty white square
empty black square
white square with specific piece on it
black square with specific piece on it.
If the variation selectors are ignored, these simplify to:
This preserves all the information; the pattern of squares is known in
advance and therefore redundant.
