              Moves  are  accepted  either  in  standard  algebraic  notation  (SAN)  or in coordinate algebraic
              notation.

              The file 'gnuchess.ini' allows setting config options if --uci is not used.  See  'info  gnuchess'
              for  details.  The  file  is  looked  for in three locations according to this precedence: current
              directory, the directory pointed to by environment variable GNUCHESS_PKGDATADIR,  or  the  package
              data directory stated at configure time.

       The  full  documentation for Chess is maintained as a Texinfo manual.  If the info and Chess programs are
       properly installed at your site, the command

              infognuchess

       should give you access to the complete manual.
