<P>Want the challenge of a good chess game? Try the gnuchess program, which
plays an extremely strong game of chess. You'll find several versions of this game installed on
your system. The gnuchess version uses cursor addressing to provide a basic graphic
display. The gnuchessr version scrolls each board after successive moves, and uses reverse
video and cursor addressing for a fancier display.
</P>
<P>Moves are entered by specifying the column and row as a letter and number. For example,

<P>To move the pawn up two squares from the lower rank, enter e2, and press the Enter
key. The computer then makes its move, and new piece positions are updated on your
display. The gnuchess program has more than 23 command-line options, and features display
play modes, hints, and timed games. For more information, see the gnuchess manual page.

Playing Emacs Games
</A></H4>
<P>The venerable emacs editor (discussed in Hour 14, "Text Processing") not only edits
text, reads mail, and handles your appointments, but also comes with 18 wacky games
and modes that you can use to pass the time, such as doctor, dunnet,
psychoanalyze-pinhead, and yow.
</P>
<P>Start an emacs game by holding down the Alt key, then pressing the x key on your
keyboard. In the command prompt at the bottom of your emacs screen type in one of the
following, and then press the Enter key: blackbox, cookie1, dissociate,
doctor, dunnet, hanoi, life,

<A NAME="PAGENUM-286"><P>Page 286</P></A>
<P>mpuz, solitaire, spook, or yow.

<P>The best way to play dunnet, a text adventure, is to use emacs from the command line:

<!-- CODE //-->

# emacs -batch -l dunnet
Dead end
You are at a dead end of a dirt road. The road goes to the east.
In the distance you can see that it will eventually fork off. The
trees here are very tall royal palms, and they are spaced equidistant
from each other.
There is a shovel here.

</PRE>
<!-- END CODE //-->
<P>This command line starts the game. At the > prompt, enter commands such as
inventory, look, or go east. To end the adventure, enter the word
quit. You'll find more games for emacs in the
/usr/share/emacs/20.2/lisp/play directory. For more details, you also can peruse the source
code for the games by installing emacs' LISP source.

Playing Chess with the xboard Client
</A></H4>
<P>Chess is a classic game, and one of the major challenges you can face is playing chess
against your computer. To play chess in X11, use the xboard client. This program can use the

</P>
<P>chess engine, and play chess over the Internet or through electronic mail (see Figure 19.2).
</P>
<P>The xboard client recognizes many X11 Toolkit options, such as geometry settings,
and has 54 different command-line options. If you have a display less than
1024¥768 pixels, you should use the -size or -boardSize
small command-line option to fit the board on your screen:
</P>
<!-- CODE SNIP //-->
<PRE>
# xboard -size small &
</PRE>
<!-- END CODE SNIP //-->
<P>This command line starts xboard using smaller chess pieces. For more details about
using xboard, see the xboard and gnuchess manual pages.

Playing X11 Solitaire
</A></H4>
<P>If you enjoy playing card solitaire games, you'll like the xpat2 X11 client. This
program features 14 different solitaire games with scoring, hints, built-in help, and sound (see
Figure 19.3).

Playing Backgammon for X11
</A></H4>
<P>For backgammon fanatics, the xgammon game will produce hours of fun and practice.
This game, by Lambert Klasen and Detlef Steuer, requires the X Window System, and
runs comfortably on an 800¥600 pixel display (see Figure 19.4).
</P>
<P>The xgammon client has 21 different command-line options. For an interesting
variation, try watching your computer play itself:

Playing Galaga for X11
</A></H4>
<P>Video action arcade games can be a lot of fun, especially if they have great graphics

client features a spiffy interface, and can be played by using your mouse or keyboard.
