      .. note::
  
          Generally probing requires tablebase files for the specific
          material composition, **as well as** tablebase files with less pieces.
          This is important because 6-piece and 5-piece files are often
          distributed seperately, but are both required for 6-piece positions.
          Use :func:`~chess.syzygy.Tablebase.add_directory()` to load
          tables from additional directories.
