+
+XBoard and WinBoard are graphical user interfaces for chess.
+XBoard runs with the X Window System on Unix systems (including
+GNU/Linux); see topic
+<A HREF="#[B.1]">[B.1]</A>.
+WinBoard runs on true 32-bit Microsoft Windows operating
+systems, such as Windows 95, 98, NT,
+2000, ME, XP, and should continue to work
+on future 32-bit Windows systems. It does
+not work on Windows CE (also known as Pocket PC), nor does it work on
+16-bit Windows systems such as Windows 3.1. See topic
+<A HREF="#[B.2]">[B.2]</A>.

+As a shortcut to most things mentioned in this FAQ, try Tim Mann's
+Chess Web page, <A HREF= "http://www.tim-mann.org/chess.html"
+>http://www.tim-mann.org/chess.html</A>. This page page is a good
+place to get the latest released versions of XBoard and WinBoard and
+the most up-to-date version of this FAQ. Also see our Savannah
+project pages at <a href="https://savannah.gnu.org/projects/xboard/"
+>https://savannah.gnu.org/projects/xboard/</a>.
+
+<p>If you have other questions about XBoard/WinBoard that aren't answered
+in this FAQ, you can try Aaron Tay's WinBoard and Chess Engines FAQ, at
+<a href="http://www.aarontay.per.sg/Winboard/"
+>http://www.aarontay.per.sg/Winboard/</a>.
+
+<P>For general news and information about chess, try the newsgroup hierarchy
+rec.games.chess.*, especially the groups rec.games.chess.misc and
+rec.games.chess.computer. Both of the latter groups have very informative
+FAQs maintained by Steve Pribut; look for them on the newsgroups or at
+<A HREF=
+"http://www.clark.net/pub/pribut/chess.html"

+
+<P>Like other GNU software, you can get XBoard, and
+WinBoard by anonymous FTP from
+<A HREF=
+"ftp://ftp.gnu.org/pub/gnu/"
+>ftp://ftp.gnu.org/pub/gnu/</A>
+and its many mirror sites. Look in the subdirectories xboard, and winboard.
+The .tar.gz suffix on the files there indicates they were packed with tar
+and compressed with gzip. The .exe or .zip suffixes indicate files that
+were packed and compressed with zip.
+
+<P>For other chess software, try the Internet Chess Library. Use anonymous FTP
+to connect to ftp.freechess.org, or go to the Web page
+<A HREF=
+"http://www.freechess.org/"
+>http://www.freechess.org/</A>.
+You can get chess software, game
+collections, the FAQ file for rec.games.chess, and other chess-related
+material there, in the directory pub/chess. The FTP server can
+automatically decompress files for you as you download them, useful if you
+don't have gzip.

+<H3><A NAME="[A.5]">[A.5] How do I report bugs, offer help, etc.?</A></H3>
+
+<P>Bug reports, suggestions, and offers to help on XBoard
+or WinBoard should be sent to
+bug-xboard<a name="nospam">@</a>gnu.org. <i>(Note: as of 4 Nov 2003,
+this mailing list is temporarily broken. You can send mail to
+bug-xboard<a name="nospam">@</a>tim-mann.org instead until it is fixed.)</i>
+
+<p>Beginner questions and discussion about the program may get faster
+answers on the WinBoard Forum at <a
+href="http://f11.parsimony.net/forum16635/"
+>http://f11.parsimony.net/forum16635/</a>.
+
+<p>If you are developing a
+chess engine that works with XBoard or WinBoard (or an alternative
+GUI that works with such engines), see the Chess Engines mailing
+list, hosted at
+<a href="http://groups.yahoo.com/group/chess-engines"
+>http://groups.yahoo.com/group/chess-engines</a>.
+
+<P>Any time you want to report a possible bug in XBoard or WinBoard,
+we need to know exactly what you did, and exactly what error (or
+other) messages you got.
+
+<P>If you are using Unix, run the "script" program, run XBoard with
+the -debug flag (if you get as far as running it), do whatever is
+necessary to reproduce the problem, type "exit" to the shell, and mail
+us the resulting typescript file. We also need to know what
+hardware/operating system combination you are using. The command
+"uname -a" will usually tell you this; include its output in your
+typescript.
+
+<P>If you are using MS Windows, run WinBoard with the -debug flag, and
+send us a copy of the WinBoard.debug file. If you aren't sure how to
+add command-line flags to WinBoard, you can hit Ctrl+Alt+F12 to create
+a WinBoard.debug file after WinBoard starts, but that is not as good,
+because a few messages that would have been printed at the start are
+lost.
+
+<p>Either way, please send us the exact text of the commands you typed
+and the output you got, not just your recollection of approximately
+what they were. The messages may seem meaningless to you, but they
+are very meaningful to us and essential for diagnosing problems.

+<h3><a name="[A.6]">[A.6] What are the future plans for XBoard and
+ WinBoard?</a></h3>
+
+<p>Our plans are always in flux. As with most free software projects,
+the next release will happen when it happens -- or it may never
+happen. This has always been the policy for XBoard/WinBoard.
+Releases have never been promised in specific time frames.
+
+<p>Starting in November 2003, several new developers have joined the
+project, and work is now hosted at <a
+href="https://savannah.gnu.org/projects/xboard/"
+>https://savannah.gnu.org/projects/xboard/</a>. Lots of work is just
+getting underway, but nothing is far along yet.
+
+<p>Here is a partial list of items that have a nonzero probability of
+happening in finite time.
+
+<ul>
+<li>Small bug fixes. Occasionally someone sends us a fix, or reports
+a small bug very clearly so that we're able to fix it in a few minutes
+work.<p>
+
+<li>Protocol version 3. The members of the chess engine authors'
+mailing list discussed a set of proposed features for the next version
+of the XBoard/WinBoard chess engine communication protocol.
+Unfortunately, this project has gotten only as far as that discussion
+took it; no revisions of the protocol spec or coding have been done
+yet. A few simple features are very clearly needed, though, and will
+probably appear in time.<p>
+
+<li>Contributed features. Several people have mailed me code to add
+various features. Most of this code is available on the
+XBoard/WinBoard extensions page at <a
+href="http://www.tim-mann.org/extensions.html"
+>http://www.tim-mann.org/extensions.html</a>, but it is not in any
+official releases yet. We are in the process of getting folks to
+formally assign the copyrights on their contributions to the Free
+Software Foundation so that we can include it in official releases in
+the future.<p>
+
+<li>Internationalization. Several people have expressed interest in
+internationalizing XBoard/WinBoard, and so hopefully this project will
+go forward. Once the internationalization support is in, we will need
+more translators. Watch for news on the xboard-devel mailing list on
+our Savannah pages.

+<HR>
+<H3><A NAME="[B.1]">[B.1] What is XBoard?</A></H3>
+
+XBoard is a graphical user interface for chess. It displays a
+chessboard on the screen, accepts moves made with the mouse, and loads
+and saves games in Portable Game Notation (PGN). XBoard is free software.
+It serves as a front-end for many different chess services, including:
+
+<p><strong>Chess engines</strong> that will run on your machine and
+play a game against you or help you analyze, such as GNU Chess and
+Crafty (topic <A HREF="#[D.3]">[D.3]</A> below).
+
+<p><strong>Chess servers</strong> on the Internet, where you can
+connect to play chess with people from all over the world, watch other
+users play, or just hang out and chat.
+
+<p><strong>Correspondence chess</strong> played by electronic
+mail. The cmail program (topic <A HREF="#[B.6]">[B.6]</A> below)
+automates the tasks of parsing email from your opponent, playing his
+moves out on your board, and mailing your reply move after you've
+chosen it.
+
+<p><strong>The Web</strong> and your own saved games. You can use
+XBoard as a helper application to view PGN games in your
+Web browser, or to load and save your own PGN files.
+
+<P>XBoard runs under Unix or Unix-compatible systems. It requires the
+X Window System, version X11R4 or later. There are also ports of
+XBoard to 32-bit Microsoft Windows and to
+the Amiga. See topics <A HREF="#[B.2]">[B.2]</A> and <A
+HREF="#[B.3]">[B.3]</A> respectively.
+
+<HR>
+<H3><A NAME="[B.2]">[B.2] Is there an XBoard for Microsoft Windows? What is WinBoard? How do I install WinBoard?</A></H3>
+
+WinBoard is a port of XBoard to 32-bit Microsoft Windows systems, such
+as Windows 95, 98, NT, 2000, ME, and XP. It uses the same back end
+chess code as XBoard, but the front end graphics code is a complete
+rewrite. WinBoard is free software.
+
+<P>The WinBoard distribution includes a port of GNU Chess to Win32.
+The GNU Chess port is distributed in executable form, with instructions for
+rebuilding it from the standard GNU Chess sources (available separately). You
+should have at least 16 to 24 MB of memory to run GNU Chess with WinBoard.
+
+<P>The WinBoard distribution also includes the ICC timestamp and FICS
+timeseal programs (topic <A HREF="#[B.12]">[B.12]</A>).
+
+<P>cmail (topic <A HREF="#[B.6]">[B.6]</A>) has not been ported to
+Windows. All the other XBoard functions are included in WinBoard.
+The International Email Chess Group web site at <a
+href="http://www.iecg.org/" >http://www.iecg.org/</a> recommends
+ECTool (<a href="http://www.ectool.nu/" >http://www.ectool.nu/</a>)
+for playing correspondence chess under Windows.
+
+<p>You install WinBoard as follows. Download the WinBoard package to
+your PC (see topic <A HREF="#[A.2]">[A.2]</A>). It will be a file
+with a name like winboard-4_0_0.exe. Double-click on this file
+in the Explorer or File Manager to run it. Follow the on-screen
+prompts.
+
+<HR>
+<H3><A NAME="[B.3]">[B.3] Is there an XBoard for the Amiga? What is AmyBoard?</A></H3>
+
+AmyBoard is a port of XBoard to the Amiga, by Jochen Wiedmann.
+The distribution includes a port of GNU Chess.
+AmyBoard is free software.
+
+<p>The current version of AmyBoard is 330.5 (based on XBoard 3.3.0).
+No one is currently maintaining it.
+
+<P>System requirements:
+
+<UL>
+<LI>An Amiga (obviously :-), running OS 2.04 or later, 2Mb RAM or more.</LI>
+<LI>MUI 2.0 or later.</LI>
+<LI>Workbench or another screen with no less than 640x400 pixels (adjustable
+ with the MUI-Prefs); this restriction is just because we don't have
+ bitmaps with less than 40x40 pixels per square. If someone contributes
+ bitmaps with 20x20 or 20x25, they will work with any Hires mode.</LI>
+</UL>
+<P>
+If you would like to use an ICS, you need an Internet connection via either
+
+<UL>
+<LI>a telnet-like program, or</LI>
+<LI>a terminal program reading from stdin and writing to stdout.</LI>
+</UL>
+<P>
+AmyBoard is available in the Internet Chess Library (topic <A HREF="#[A.2]">[A.2]</A>).
+
+<HR>
+<H3><A NAME="[B.4]">[B.4] Is there an XBoard for the Macintosh?</A></H3>
+
+Because MacOS X has a Unix base, XBoard will compile and run on it.
+You do need an X11 (X Window System) server and client libraries.
+These do not come with Mac OS, but both free and commercial versions
+are available. Once you install the X11 package, XBoard is reported
+to compile and run without changes. I am not a Mac user and have not
+tried this myself, so I cannot answer questions about it.
+
+Version 4.2.6 and earlier of XBoard come with an old copy of the
+config.sub utility that does not recognize Mac OS X, so to build
+XBoard, you'll have to tell the configure program what OS you are
+running. Follow the instructions in topic <A HREF="#[B.7]">[B.7]</A>
+of this FAQ, but add the argument <tt>--host=powerpc-apple-bsd</tt> to
+the end of the "configure" command line.
+
+There is no version of XBoard or WinBoard that runs with the native
+(non-X11) Mac graphical interface, and none that runs on MacOS 9 or
+earlier.
+
+
+<HR>
+<H3><A NAME="[B.5]">[B.5] Does XBoard run on VMS?</A></H3>
+
+No. This port would probably be a lot easier than the Win32 and Amiga
+ports were, because VMS has the X Window system (under the name
+DECwindows) and is now POSIX compliant. However, I don't know enough
+about VMS to do the port myself, and I don't have time. If you do,
+give it a try! Send mail to me,
+tim<a name="nospam2">@</a>tim-mann.org (Tim Mann), if you're
+working on this.
+
+<HR>
+<H3><A NAME="[B.6]">[B.6] What is cmail?</A></H3>
+
+cmail is a program that helps you play and keep track of electronic mail
+correspondence chess games using XBoard. It is distributed with XBoard and
+has its own manual page. cmail is free software. It was written by
+Even Welsh. cmail has not been ported to Windows; sorry.
+
+<HR>
+<H3><A NAME="[B.7]">[B.7] How do I build XBoard? Do I need gcc?</A></H3>
+
+The first step to building XBoard is to get the distribution file. See topic
+<A HREF="#[A.2]">[A.2]</A> for places you can ftp the software from.
+
+<P>Next, decide what directory tree you are going to install XBoard
+in. The default is /usr/local, but you probably don't have write
+access to that directory unless you are a system administrator. If
+you do, type the following to install it there:
+
+<p><PRE>
+ gzip -cd xboard-*.tar.gz | tar -xvf -
+ cd xboard-*/
+ ./configure
+ make
+ su
+ make install
+</PRE>

+
+The only way for two humans on different machines to play chess in
+real time using XBoard/WinBoard is to use an Internet Chess Server
+as an intermediary. That is, each player runs his own copy of XBoard
+or WinBoard, both of them log into an ICS, and they play a game there.
+Two copies of XBoard/WinBoard cannot communicate with each other
+directly.
+
+<P>Instructions on how to get started with Internet chess are included
+with the XBoard and WinBoard distributions. The network addresses
+included in the distribution may not always be current. The oldest
+and largest ICS is the Internet Chess Club at chessclub.com, which now
+has a fee for registered use, but still allows free unregistered use.
+There are also many newer sites with no fees, using the Free Internet
+Chess Server implementation (FICS). The most active FICS site is
+freechess.org. On these and most other chess servers,
+the port number to use is 5000.
+
+<P>If you don't have network connectivity to any ICS site, you
+can run your own server using a version of the FICS code, but this

+
+Zippy is an interface that lets a compatible chess engine (such as GNU

+XBoard and WinBoard distributions. It is implemented as a small
+amount of additional code within XBoard or WinBoard.
+For documentation, see the file

+You'll also find a "biography" of Zippy and pointers to the original
+Zippy the Pinhead comic strips on my Web page.
+Please read zippy.README carefully before you ask me any questions about Zippy.
+
+<p>Using a computer to choose your moves on a chess server is
+considered cheating unless your account is on the computer (C) list.
+Read "help computer" on your favorite server for details on their

+
+This is a non-trivial task. XBoard and WinBoard were not designed

+written to work with an existing version of GNU Chess that expects to
+be talking to a person. Your program has to emulate GNU Chess's

+The source code for WinBoard is available from the author's Web page,
+<A HREF=
+"http://www.tim-mann.org/chess.html"
+>http://www.tim-mann.org/chess.html</A>.
+
+<p>WinBoard is currently developed using Microsoft Visual C++ 5.0.
+You can build the program from the MSVC++ GUI by opening the project
+file (winboard.dsp) and telling MSVC++ to build the project. You can
+also build it from the the command line by using the nmake program
+supplied with MSVC++.
+
+<p>To build WinBoard with the free Cygwin tools, available from <a
+href= "http://www.cygwin.com/" >http://www.cygwin.com/</a>), use the
+command "make -f cygwin.mak". WinBoard 4.2.5 was successfully
+compiled with the net release of Cygwin as downloaded on 20-March-2001
+(cygwin1.dll 1.1.8, gcc 2.95.2-6, binutils 20001221-1, flex 2.5.4-1),
+but exhibits a command-line parsing bug; see item 511 in the ToDo file
+that comes with WinBoard. WinBoard 4.1.0 does not compile with
+Cygwin. WinBoard 4.0.7 is known to compile with Cygwin BL20.1.
+
+<p>To build WinBoard with Borland C++ 4.5, use "borland.mak", supplied
+with the WinBoard sources, as the Makefile. Support for Borland C++
+was contributed by Don Fong and has not been tested by the author of WinBoard.
+
+<p>WinBoard is a Win32 application, so you definitely need a compiler
+and tool set that supports Win32. In particular, older versions of
+DJGPP can build only 32-bit MSDOS programs; that is, programs that use
+a DOS extender to get a 32-bit address space and do not make any
+Windows calls. The latest versions of DJGPP are said to be able to
+build Win32 programs when used with the proper extension package(s),
+but this is not known to work with WinBoard. Use Cygwin instead.

+How can I use XBoard or WinBoard to talk
+to an Internet Chess Server through a firewall or proxy?
+</A></H3>
+
+<p>There is no single answer to this question, because there are many
+different kinds of firewalls in use. They work in various different
+ways and have various different security policies. This answer can
+only provide hints.
+
+<p>Note that you can't access Internet Chess Servers through a Web proxy,
+because they are not a Web service. You talk to them through a raw
+TCP connection, not an HTTP connection. If you can only access the
+Web through a proxy, there may be a firewall that stops you from
+making direct TCP connections, but there may also be a way through it.
+Read on for hints, and contact your local system administrator if you
+need more information about your local configuration.
+
+<p>A helpful user mailed me the following explanation of how to use
+WinBoard with WinGate:
+<blockquote>
+"I have managed to setup WinBoard though my WinGate proxy. I have the
+Office version. What I needed to do was to setup the TCP/IP
+connection to add the User/Host name and my provider service name for
+the DNS, but I had to leave the HOST IP address blank. I have not
+played with all the variations, so it may be just that I have the DNS
+lookup enabled."
+</blockquote>
+I hope this helps, though I don't find it very clear. I don't have
+a copy of WinGate myself and can't help if you have questions about it.
+
+<p>If you are using some other non-SOCKS firewall, read the FIREWALLS section
+in your XBoard or WinBoard documentation (man page, info document, or
+Help file). If you can telnet to a chess server in some way, then you
+can almost certainly connect to it with xboard/WinBoard, though in
+some cases you may not be able to run timestamp or timeseal. The
+timestamp and timeseal protocols require a clean, 8-bit wide TCP
+connection from your machine to the ICS, which some firewalls do not
+provide.
+
+<p>If you have a SOCKS firewall and are using <strong>XBoard</strong>,
+you should be able to SOCKSify xboard and use it. See <a
+href="http://www.socks.nec.com/">http://www.socks.nec.com/</a> for
+information about SOCKS and socksification. However, if you do this,
+you can't use timestamp or timeseal; what you really need is a
+socksified version of timestamp or timeseal. This is hard because the
+source code for timestamp and timeseal is proprietary; the folks
+running the chess servers don't give it out because that would make it
+too easy to cheat. On some versions of Unix, you may be able to
+socksify a program that you don't have the source code to by running
+it with an appropriate dynamic library; see <a
+href="http://www.socks.nec.com/">http://www.socks.nec.com/</a>. For
+others, you might be able to get a pre-built socksified version from
+the chess server administrators. For timeseal versions, see <a
+href="ftp://ftp.freechess.org/pub/chess/timeseal/"
+>ftp://ftp.freechess.org/pub/chess/timeseal/</a>. For timestamp
+versions, the directory would be <a
+href="ftp://ftp.chessclub.com/pub/icc/timestamp/"
+>ftp://ftp.chessclub.com/pub/icc/timestamp/</a>, but at this writing
+there don't seem to be any socksified timestamps there. Once you have
+a socksified timestamp or timeseal, simply run it with a normal,
+non-socksified xboard in place of the standard timestamp or timeseal.
+
+<p>If you have a SOCKS firewall and you are using
+<strong>WinBoard</strong>, we now know how to make this configuration
+work, complete with timestamp or timeseal!
+
+<p>Start by getting SocksCap32. This software is freely available
+from <a href="http://www.socks.nec.com/">http://www.socks.nec.com/</a>.
+Install it on your machine, read the documentation, and learn to use
+it. You may find it useful with many other programs besides WinBoard.
+
+<p>Next, <strong>don't</strong> socksify WinBoard. Socksifying
+WinBoard itself doesn't let you use it with timestamp or timeseal.
+For some reason I don't understand -- something strange that
+SocksCap32 does -- the socksified WinBoard runs but does nothing, and
+timestamp/timeseal runs all by itself in its own window.
+
+<p>Instead, use the following workaround. Follow the instructions
+exactly; don't try to skip steps or simplify things.
+
+<p>First, make SocksCap32 application profiles for timestamp and
+timeseal. Use the following command lines in the SocksCap32
+profiles. Name the first profile "timestamp" and the second
+"timeseal".
+
+<p><pre>
+ "c:\program files\winboard\timestamp.exe" chessclub.com 5000 -p 5000
+ "c:\program files\winboard\timeseal.exe" freechess.org 5000 -p 5000
+</pre>
+
+<p>Second, run timestamp or timeseal by itself, socksified, using its
+profile. This will open an unneeded, black window that will not
+respond to typing. Minimize it to the task bar and ignore it. It will
+go away when you exit from WinBoard.
+
+<p>Next, run WinBoard using the following command line. Make a shortcut
+or type this command into an MS-DOS Prompt box. Don't run WinBoard
+itself socksified, just run it directly.
+
+<p><pre>
+ "c:\program files\winboard.exe" /ics /icshost=localhost /icsport=5000
+</pre>
+
+<p>After you get this working, you can try getting the timestamp window to
+auto-minimize by starting it from a shortcut instead of from the
+SocksCap32 control window. As it says in the SocksCap32 help file, put
+the following in the Target field of a shortcut's Properties page:
+
+<p><pre>
+ "c:\program files\sockscap32\sc32.exe" timestamp
+</pre>
+
+Then select "Run: Minimized" on the same page. Do the same for timeseal.
+
+<p>Another method that can work is to use a .bat file to start both
+timestamp and WinBoard. It would look something like this:
+
+<p><pre>
+ REM --
+ REM -- icc.bat
+ REM -- Start timestamp under SocksCap32 and use WinBoard to connect to it.
+ REM -- The string "timestamp" refers to a SocksCap32 profile for timestamp.
+ REM -- Do not change it to the filename of the timestamp program!
+ REM --
+ start /minimized "c:\program files\sockscap32\sc32.exe" timestamp
+ cd "c:\program files\winboard"
+ winboard /ics /icshost=localhost /icsport=5000
+</pre>
+
+<p>This workaround has a problem if you want to run two copies of
+WinBoard at once, talking to the same chess server twice (for
+bughouse) or to two different chess servers. If you need to do that,
+you will need to run a separate copy of timestamp with <i>a different
+port number</i> for each connection. You'll need to make a second set of
+profile entries with a different value after the -p flag (say, 5001)
+and you'll need to change the WinBoard command line /icsport=5000 for
+the second WinBoard to match.

+WinBoard) that automatically restarts the program whenever it exits.
+Use the -xexit flag so that you don't get a popup dialog that must be
+dismissed with the OK button before the program will exit. The gap in
+this solution is that your connection to ICS can sometimes get into a
+state where the program does not notice that the connection is broken
+until the next time it tries to send a command. Perhaps some future
+version of xboard/WinBoard will have an option to send a harmless
+command every five minutes or so.
+
+<p>Anyway, here is a sample Windows .bat file that restarts WinBoard each
+time it exits. Thanks to Jason Williamson. It assumes that you have put
+your computer account's name and password in a file named logon.ini.

+
+Perhaps you have the X server and client programs installed on your
+machine, but not the X header files and link-time libraries. If so,
+you can run existing X programs, but you cannot compile a new X
+program from source code. In this case the XBoard configure script
+will fail and will tell you to look at this question in the FAQ. Many
+GNU/Linux distributions put the headers and libraries in a separate
+package, which you might not have installed. If you are using RedHat,
+install the XFree86-devel package. If you are using some other
+kind of Unix, ask your system administrator where to find the X header
+files and link-time libraries. If this is not your problem, read on.
+
+<p>The configure script for XBoard looks for X libraries and header
+files in some common places. Sometimes it fails: If yours are
+installed in an odd place, it may not find them at all. If you have
+more than one version of X installed on your system, it may find the
+"wrong" one, or occasionally it may find libraries from one version
+and incompatible header files from another. You can work around these
+problems by telling the configure script where the files are. For
+example:
+
+<p><PRE>
+ configure --x-includes=/odd/place/include \
+ --x-libraries=/odd/place/lib
+</PRE>
+
+<P>The directory named in the argument to --x-includes must have a
+subdirectory "X11" that contains the actual .h files. That is, if
+your X.h file has full pathname /odd/place/X11R6/include/X11/X.h, then
+you must give the argument --x-includes=/odd/place/X11R6/include.
+
+<P>Some linkers have bugs that cause bogus error messages when you try
+to link X programs. The configure script includes a workaround for a
+bug of this kind that exists in some SunOS 4.x.x installations. See
+the FAQ on comp.windows.x for more information about problems of this
+kind.
+
+<P>If all else fails, check whether anyone else at your site has been able to

+Why do my ICS

+Why do I sometimes lose time off my clock after I make my move?
+</a></h3>
+
+If you are playing with the ICS incremental clock, both you and your
+opponent get a set amount of extra time after each move.
+
+<p>If your or your opponent has netlag, your opponent might appear to
+get extra time, especially if your opponent is using timestamp or
+timeseal. The ICS charges each player who is using timestamp or
+timeseal only for the time between when the player received his
+opponent's move and the time he sent his own move. Thus delays in
+network transmission do not count against either player. But WinBoard
+counts down the display of your opponent's clock on your screen under
+the assumption that there is no netlag. When his move comes in, if
+there was netlag, the ICS may not have really charged him for that
+much time, and WinBoard corrects the clock to what the ICS says it
+should read.
+
+<p>If you are not using timestamp or timeseal, you may appear to lose
+time off your clock at some point after you make your move. In this
+case, the ICS charges you for the time between when it sent you your
+opponent's move and the time it received your move. Thus delays in
+network transmission count against you. WinBoard stops counting down
+the display of your clock on your screen (and starts your opponent's)
+when you make your move. When the ICS echoes your move back to you, it
+may have charged you for more time than that, and WinBoard corrects
+the clocks to what the ICS says they should read.

+<p>See "help lag" and "help timestamp" or "help timeseal" on your ICS for

+<p>First, you need to get Crafty and install it as a command-line
+application on your machine. See topic <A HREF="#[D.3]">[D.3]</A>.
+
+<p>To use Crafty with XBoard, give the -fcp
+parameter like this:
+
+<p><PRE>
+ xboard -fcp "./crafty" -fd <I>crafty_directory</I>
+</PRE>
+
+Here <I>crafty_directory</I> is the directory where you installed Crafty.
+You can add more xboard options at the end of the command line.
+
+<p>Crafty 15.14 or later is required to work properly with XBoard
+4.0.0 or later. We generally recommend using the latest versions of
+both XBoard and Crafty.

+<H3><A NAME="[D.5]">[D.5] How do I use Crafty with WinBoard?</A></H3>
+
+<p>First, you need to get Crafty and install it as a command-line
+application on your machine. See topic <A HREF="#[D.3]">[D.3]</A>.
+It is best to use the latest version of Crafty with the latest version
+of WinBoard to make sure all features are compatible and function
+correctly. You can install Crafty in any directory you like.
+
+<p>You also need to get WinBoard and install it in the normal way
+using its built-in installer. You can do that either before or after
+you install Crafty.
+
+<p>After both Crafty and WinBoard are installed separately, follow the
+directions in the WinBoard Help file (included with WinBoard) for
+connecting new chess engines to WinBoard.
+
+<p>If you want to have Crafty act as an automated computer player on a
+chess server, see topic <A HREF="#[B.16]">[B.16]</A>. Before you try
+to get that working, be sure you can play against Crafty locally,
+first without WinBoard, then with it. Also be sure you can use
+WinBoard to play on the chess server yourself, without having Crafty
+connected to it. You have to crawl before you can walk!

+<H3><A NAME="[D.6]">[D.6] How do I use GNU Chess 5 with XBoard?</A></H3>
+
+<p>By default, XBoard still tries to use GNU Chess 4 by running the
+command "gnuchessx". That's why if you don't have GNU Chess 4, you
+get the error message "Failed to start first chess program gnuchessx
+on localhost: gnuchessx: No such file or directory."
+
+<p>If you have GNU Chess 5, the command should be "gnuchess xboard"
+instead. To make XBoard use this command, give the -fcp parameter
+like this:
+
+<p><PRE>
+ xboard -fd <I>gnuchess_directory</I> -fcp "./gnuchess xboard"
+</PRE>
+
+Here <I>gnuchess_directory</I> is the directory where you installed
+GNU Chess 5 and its book. You can add more xboard options at the
+end of the command line.
