Go up one level in this thread


I have had to complete the foolwing chapter:


Extra savings
-------------

If 16 piece placements of one color are known, color bits will stop.

If 8 pawns of one color are known, the pawn selection is ommitted for
that color (also at inner lines). Of course second queens and bishops
upon same colored squares will be counted as promoted pawns like third
Rooks, Bishops or Knights.

No savings when encoding a 16th piece of one color, because the set
of used officers has not been reduced to the initial piece set to
make the coding scheme more flexible in general.
