Actually, I'm using the "-xclock" option to avoid time limits.

I think I haven't got any opening books installed: there's nothing for
GnuChess in /usr/share/games, and a 'locate -i gnuchess' only finds the
tarball's directory and 3 binaries:

        /usr/local/bin/gnuchess
        /usr/local/bin/gnuchessx
        /usr/local/bin/gnuchessx.org

Unfortunately, glChess doesn't have a -debug option, but a 'lsof'
reports that the GnuChess launched by glChess has the following files
open, both at game start and after the first 2 moves:

Not knowing GnuChess' internals, I'm not sure that the above is
relevant, but it looks like there is no book file open at the moment.
