131 <h3><a name="tag-A.1">[A.1] What are XBoard and WinBoard?</a></h3>
133 <p>XBoard and WinBoard are graphical user interfaces for chess.
134 XBoard runs with the X Window System on Unix systems (including
135 GNU/Linux); see topic <a href="#tag-B.1">[B.1]</a>. WinBoard runs
136 on true 32-bit Microsoft Windows operating systems, such as Windows
137 95, 98, NT, 2000, ME, XP, Vista, and should continue to work on future
138 32-bit Windows systems. It does not work on Windows CE (also known
139 as Pocket PC), nor does it work on 16-bit Windows systems such as
140 Windows 3.1. See topic <a href="#tag-B.2">[B.2]</a>.</p>
143 <h3><a name="tag-A.2">[A.2] Where can I get chess information and chess

149 This page page is currently a very bad place to get the latest released
150 versions of XBoard and WinBoard and the most up-to-date version of this

175 <p>Like other GNU software, you can get XBoard, and WinBoard by anonymous FTP from
176 <a href="ftp://ftp.gnu.org/pub/gnu/">ftp://ftp.gnu.org/pub/gnu/</a>
177 and its many mirror sites. Look in the subdirectories xboard, and winboard.
178 The .tar.gz suffix on the files there indicates they were packed with tar
179 and compressed with gzip. The .exe or .zip suffixes indicate files that
180 were packed and compressed with zip.</p>

239 This forum also constains a section dedicated to propose and discuss
240 new features for WinBoard / XBoard or WinBoard protocol,
242 and offers downloads of pre-installed packages of WinBoard
243 bundled with other software,
244 useful for conducting computer-computer tournaments.</p>
246 <p>If you are developing a
247 chess engine that works with XBoard or WinBoard (or an alternative
248 GUI that works with such engines), see the Chess Engines mailing
250 <a href="http://groups.yahoo.com/group/chess-engines"

253 or the <a href="http://www.talkchess.com/forum">CCC forum</a>.</p>
256 <p>Any time you want to report a possible bug in XBoard or WinBoard,
257 we need to know exactly what you did, and exactly what error (or
258 other) messages you got.</p>
260 <p>If you are using Unix, run the "script" program, run XBoard with
261 the -debug flag (if you get as far as running it), do whatever is
262 necessary to reproduce the problem, type "exit" to the shell, and mail
263 us the resulting typescript file. We also need to know what
264 hardware/operating system combination you are using. The command
265 "uname -a" will usually tell you this; include its output in your
268 <p>If you are using MS Windows, run WinBoard with the -debug flag, and
269 send us a copy of the WinBoard.debug file. If you aren't sure how to
270 add command-line flags to WinBoard, you can hit Ctrl+Alt+F12 to create
271 a WinBoard.debug file after WinBoard starts, but that is not as good,
272 because a few messages that would have been printed at the start are
275 <p>Either way, please send us the exact text of the commands you typed
276 and the output you got, not just your recollection of approximately
277 what they were. The messages may seem meaningless to you, but they
278 are very meaningful to us and essential for diagnosing problems.</p>
281 <h3><a name="tag-A.6">[A.6] What are the future plans for XBoard and
284 <p>Our plans are always in flux. As with most free software projects,
285 the next release will happen when it happens -- or it may never
286 happen. This has always been the policy for XBoard/WinBoard.
287 Releases have never been promised in specific time frames.</p>
289 <p>Starting in November 2003, several new developers have joined the
290 project, and work is now hosted at <a
291 href="https://savannah.gnu.org/projects/xboard/"
292 >https://savannah.gnu.org/projects/xboard/</a>. Lots of work is just
293 getting underway, but nothing is far along yet.</p>
295 <p>Here is a partial list of items that have a nonzero probability of
296 happening in finite time.</p>
299 <li>Small bug fixes. Occasionally someone sends us a fix, or reports
300 a small bug very clearly so that we're able to fix it in a few minutes
303 <li>Protocol version 3. The members of the chess engine authors'
304 mailing list discussed a set of proposed features for the next version
305 of the XBoard/WinBoard chess engine communication protocol.
306 The WinBoard 4.3 fork has taken the protocol in a different direction,
307 though, extending version 2 with new features as they were needed,
308 rather than upgrading to a new protocol in a single sweep.
309 It does not seem likely that there will be a v3 protocol in the
313 <li>Contributed features. Several people have mailed me code to add
314 various features. Most of this code is available on the
315 XBoard/WinBoard extensions page
316 at <a href="http://www.tim-mann.org/extensions.html">
317 http://www.tim-mann.org/extensions.html</a>,
318 but it is not in any official releases yet. We are in the process of
319 getting folks to formally assign the copyrights on their contributions
320 to the Free Software Foundation so that we can include it in official
321 releases in the future.</li>
323 <li>Internationalization. Several people have expressed interest in
324 internationalizing XBoard/WinBoard. Version 4.4 implements
325 internationalization in its XBoard branch, and includes (partial)
326 Turkish and German translations. For WinBoard a suitable way for
327 internationalization still has to be found, as all menu strings there
328 are not in the C code, but in a Windows resource file. In any case, we
329 will need more translators, to update the existing translations (for
330 version 4.2.7) to the current version, and to provide translaions for
331 oter languages. Watch for news on the xboard-devel mailing list on
332 our Savannah pages.</li>
337 <H2><a name="tag-B">[B] XBoard and WinBoard</a></H2>
339 <h3><a name="tag-B.1">[B.1] What is XBoard?</a></h3>
341 <p>XBoard is a graphical user interface for chess. It displays a
342 chessboard on the screen, accepts moves made with the mouse, and loads
343 and saves games in Portable Game Notation (PGN). XBoard is free software.
344 It serves as a front-end for many different chess services, including:</p>
346 <p><strong>Chess engines</strong> that will run on your machine and
347 play a game against you or help you analyze, such as GNU Chess and
348 Crafty (topic <a href="#tag-D.3">[D.3]</a> below).</p>
350 <p><strong>Chess servers</strong> on the Internet, where you can
351 connect to play chess with people from all over the world, watch other
352 users play, or just hang out and chat.</p>
354 <p><strong>Correspondence chess</strong> played by electronic
355 mail. The cmail program (topic <a href="#tag-B.6">[B.6]</a> below)
356 automates the tasks of parsing email from your opponent, playing his
357 moves out on your board, and mailing your reply move after you've
360 <p><strong>The Web</strong> and your own saved games. You can use
361 XBoard as a helper application to view PGN games in your
362 Web browser, or to load and save your own PGN files.</p>
364 <p>XBoard runs under Unix or Unix-compatible systems. It requires the
365 X Window System, version X11R4 or later. There are also ports of
366 XBoard to 32-bit Microsoft Windows and to
367 the Amiga. See topics <a href="#tag-B.2">[B.2]</a> and <a
368 HREF="#tag-B.3">[B.3]</a> respectively.</p>
371 <h3><a name="tag-B.2">[B.2] Is there an XBoard for Microsoft Windows? What is WinBoard? How do I install WinBoard?</a></h3>
373 <p>WinBoard is a port of XBoard to 32-bit Microsoft Windows systems, such
374 as Windows 95, 98, NT, 2000, ME, and XP. It uses the same back end
375 chess code as XBoard, but the front end graphics code is a complete
376 rewrite. WinBoard is free software.</p>
378 <p>The WinBoard distribution includes a sample Chess engine.</p>
380 <p>The WinBoard distribution also includes the ICC timestamp and FICS
381 timeseal programs (topic <a href="#tag-B.12">[B.12]</a>).</p>
383 <p>cmail (topic <a href="#tag-B.6">[B.6]</a>) has not been ported to
384 Windows. All the other XBoard functions are included in WinBoard.
385 The International Email Chess Group web site at <a
386 href="http://www.iecg.org/" >http://www.iecg.org/</a> recommends
387 ECTool (<a href="http://www.ectool.nu/" >http://www.ectool.nu/</a>)
388 for playing correspondence chess under Windows.</p>
390 <p>You install WinBoard as follows. Download the WinBoard package to
391 your PC (see topic <a href="#tag-A.2">[A.2]</a>). It will be a file
392 with a name like winboard-4_0_0.exe. Double-click on this file
393 in the Explorer or File Manager to run it. Follow the on-screen
397 <h3><a name="tag-B.3">[B.3] Is there an XBoard for the Amiga? What is AmyBoard?</a></h3>
399 <p>AmyBoard is a port of XBoard to the Amiga, by Jochen Wiedmann.
400 The distribution includes a port of GNU Chess.
401 AmyBoard is free software.</p>
403 <p>The current version of AmyBoard is 330.5 (based on XBoard 3.3.0).
404 No one is currently maintaining it.</p>
406 <p>System requirements:</p>
409 <li>An Amiga (obviously :-), running OS 2.04 or later, 2Mb RAM or more.</li>
410 <li>MUI 2.0 or later.</li>
411 <li>Workbench or another screen with no less than 640x400 pixels (adjustable
412 with the MUI-Prefs); this restriction is just because we don't have
413 bitmaps with less than 40x40 pixels per square. If someone contributes
414 bitmaps with 20x20 or 20x25, they will work with any Hires mode.</li>
417 <p>If you would like to use an ICS, you need an Internet connection via either</p>
420 <li>a telnet-like program, or</li>
421 <li>a terminal program reading from stdin and writing to stdout.</li>
424 <p>AmyBoard is available in the Internet Chess Library (topic <a href="#tag-A.2">[A.2]</a>).</p>
427 <h3><a name="tag-B.4">[B.4] Is there an XBoard for the Macintosh?</a></h3>
429 <p>Note: I am not a Mac user and have not tried this myself, so I cannot
430 answer questions about it. </p>
432 <p>Because MacOS X has a Unix base, XBoard will compile and run on it.
433 You do need an X11 (X Window System) server and client libraries. I'm
434 told that these come standard with MacOS X 10.3 and later. Once you
435 install the X11 package, XBoard is reported to compile and run without
438 <p>You can avoid having to compile XBoard (and GNU Chess) yourself by
439 using the Fink sofware packaging system. See

449 <h3><a name="tag-B.5">[B.5] Does XBoard run on VMS?</a></h3>
451 <p>No. This port would probably be a lot easier than the Win32 and Amiga
452 ports were, because VMS has the X Window system (under the name
453 DECwindows) and is now POSIX compliant. If you are working on this,
454 send mail to bug-xboard<a name="nospam02">@</a>gnu.org to let us know.</p>
458 <h3><a name="tag-B.6">[B.6] What is cmail?</a></h3>
460 <p>cmail is a program that helps you play and keep track of electronic mail
461 correspondence chess games using XBoard. It is distributed with XBoard and
462 has its own manual page. cmail is free software. It was written by
463 Even Welsh. cmail has not been ported to Windows; sorry.</p>
466 <h3><a name="tag-B.7">[B.7] How do I build XBoard? Do I need gcc?</a></h3>
468 <p>The first step to building XBoard is to get the distribution file. See topic
469 <a href="#tag-A.2">[A.2]</a> for places you can ftp the software from.</p>
471 <p>Next, decide what directory tree you are going to install XBoard
472 in. The default is /usr/local, but you probably don't have write
473 access to that directory unless you are a system administrator. If
474 you do, type the following to install it there:</p>
477 gzip -cd xboard-*.tar.gz | tar -xvf -
485 <p>If you want to install xboard in your personal home directory ($HOME/bin),
489 gzip -cd xboard-*.tar.gz | tar -xvf -
491 ./configure --prefix=$HOME
496 <p>If the first step above fails because you don't have gzip, see
497 topic <a href="#tag-A.2">[A.2]</a>, and ask a local Unix expert if you
498 need more help. If you have any problems with the last two steps,
499 read the READ_ME and INSTALL files in the xboard-*/ directory. You
500 will also find this FAQ there.</p>
502 <p>You don't need to have gcc to build XBoard. Almost any Unix C
503 compiler should do.</p>

509 <p>The only way for two humans on different machines to play chess in
510 real time using XBoard/WinBoard is to use an Internet Chess Server
511 as an intermediary. That is, each player runs his own copy of XBoard

517 with the XBoard and WinBoard distributions. The network addresses
518 included in the distribution may not always be current. The oldest
519 and largest ICS is the Internet Chess Club at chessclub.com, which now
520 has a fee for registered use, but still allows free unregistered use.
521 There are also many newer sites with no fees, using the Free Internet
522 Chess Server implementation (FICS). The most active FICS site is
523 freechess.org. On these and most other chess servers,
524 the port number to use is 5000.</p>
526 <p>If you don't have network connectivity to any ICS site, you
527 can run your own server using a version of the FICS code, but this
528 is not easy. See <a href="http://www.tim-mann.org/ics.html#ownics"

547 not even with the Win32s compatibility package. The main problem is
548 that Win32s does not have threads or real concurrent processes. A

700 <p>Zippy is an interface that lets a compatible chess engine (such as GNU
701 Chess or Crafty) act as a computer
702 player on an Internet Chess Server. Zippy is included in both the
703 XBoard and WinBoard distributions. It is implemented as a small
704 amount of additional code within XBoard or WinBoard.
705 For documentation, see the file
706 zippy.README, included in both distributions or available
707 from my chess Web page,
709 "http://www.tim-mann.org/chess.html"
710 >http://www.tim-mann/chess.html</a>.
711 The version of zippy.README on my Web page is often more up-to-date
712 than those in the XBoard/WinBoard distributions.
713 You'll also find a "biography" of Zippy and pointers to the original
714 Zippy the Pinhead comic strips on my Web page.
715 Please read zippy.README carefully before you ask me any questions about Zippy.</p>
717 <p>Using a computer to choose your moves on a chess server is
718 considered cheating unless your account is on the computer (C) list.
719 Read "help computer" on your favorite server for details on their
720 policy. Most of the servers have plenty of computers running now, so they
721 will not be excited about having you run a new one unless you have
722 written your own chess engine. They don't really need yet another

729 <p>This is a non-trivial task. XBoard and WinBoard were not designed
730 with a clean interface for talking to chess programs; they were
731 written to work with an existing version of GNU Chess that expects to
732 be talking to a person. Your program has to emulate GNU Chess's
733 rather idiosyncratic command structure to work with XBoard and

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

792 How can I use XBoard or WinBoard to talk
793 to an Internet Chess Server through a firewall or proxy?
796 <p>There is no single answer to this question, because there are many
797 different kinds of firewalls in use. They work in various different
798 ways and have various different security policies. This answer can
799 only provide hints.</p>
801 <p>Note that you can't access Internet Chess Servers through a Web proxy,
802 because they are not a Web service. You talk to them through a raw
803 TCP connection, not an HTTP connection. If you can only access the
804 Web through a proxy, there may be a firewall that stops you from
805 making direct TCP connections, but there may also be a way through it.
806 Read on for hints, and contact your local system administrator if you
807 need more information about your local configuration.</p>
809 <p>A helpful user mailed me the following explanation of how to use
810 WinBoard with WinGate:</p>
812 "I have managed to setup WinBoard though my WinGate proxy. I have the
813 Office version. What I needed to do was to setup the TCP/IP
814 connection to add the User/Host name and my provider service name for
815 the DNS, but I had to leave the HOST IP address blank. I have not
816 played with all the variations, so it may be just that I have the DNS
819 <p>I hope this helps, though I don't find it very clear. I don't have
820 a copy of WinGate myself and can't help if you have questions about it.</p>
822 <p>If you are using some other non-SOCKS firewall, read the FIREWALLS section
823 in your XBoard or WinBoard documentation (man page, info document, or
824 Help file). If you can telnet to a chess server in some way, then you
825 can almost certainly connect to it with xboard/WinBoard, though in
826 some cases you may not be able to run timestamp or timeseal. The
827 timestamp and timeseal protocols require a clean, 8-bit wide TCP
828 connection from your machine to the ICS, which some firewalls do not
831 <p>If you have a SOCKS firewall and are using <strong>XBoard</strong>,
832 you should be able to SOCKSify xboard and use it. See <a
833 href="http://www.socks.nec.com/">http://www.socks.nec.com/</a> for
834 information about SOCKS and socksification. However, if you do this,
835 you can't use timestamp or timeseal; what you really need is a
836 socksified version of timestamp or timeseal. This is hard because the
837 source code for timestamp and timeseal is proprietary; the folks
838 running the chess servers don't give it out because that would make it
839 too easy to cheat. On some versions of Unix, you may be able to
840 socksify a program that you don't have the source code to by running
841 it with an appropriate dynamic library; see <a
842 href="http://www.socks.nec.com/">http://www.socks.nec.com/</a>. For
843 others, you might be able to get a pre-built socksified version from
844 the chess server administrators. For timeseal versions, see <a
845 href="ftp://ftp.freechess.org/pub/chess/timeseal/"
846 >ftp://ftp.freechess.org/pub/chess/timeseal/</a>. For timestamp
847 versions, the directory would be <a
848 href="ftp://ftp.chessclub.com/pub/icc/timestamp/"
849 >ftp://ftp.chessclub.com/pub/icc/timestamp/</a>, but at this writing
850 there don't seem to be any socksified timestamps there. Once you have
851 a socksified timestamp or timeseal, simply run it with a normal,
852 non-socksified xboard in place of the standard timestamp or timeseal.</p>
854 <p>If you have a SOCKS firewall and you are using
855 <strong>WinBoard</strong>, we now know how to make this configuration
856 work, complete with timestamp or timeseal!</p>
858 <p>Start by getting SocksCap32. This software is freely available
859 from <a href="http://www.socks.nec.com/">http://www.socks.nec.com/</a>.
860 Install it on your machine, read the documentation, and learn to use
861 it. You may find it useful with many other programs besides WinBoard.</p>
863 <p>Next, <strong>don't</strong> socksify WinBoard. Socksifying
864 WinBoard itself doesn't let you use it with timestamp or timeseal.
865 For some reason I don't understand -- something strange that
866 SocksCap32 does -- the socksified WinBoard runs but does nothing, and
867 timestamp/timeseal runs all by itself in its own window.</p>
869 <p>Instead, use the following workaround. Follow the instructions
870 exactly; don't try to skip steps or simplify things.</p>
872 <p>First, make SocksCap32 application profiles for timestamp and
873 timeseal. Use the following command lines in the SocksCap32
874 profiles. Name the first profile "timestamp" and the second
878 "c:\program files\winboard\timestamp.exe" chessclub.com 5000 -p 5000
879 "c:\program files\winboard\timeseal.exe" freechess.org 5000 -p 5000
882 <p>Second, run timestamp or timeseal by itself, socksified, using its
883 profile. This will open an unneeded, black window that will not
884 respond to typing. Minimize it to the task bar and ignore it. It will
885 go away when you exit from WinBoard.</p>
887 <p>Next, run WinBoard using the following command line. Make a shortcut
888 or type this command into an MS-DOS Prompt box. Don't run WinBoard
889 itself socksified, just run it directly.</p>
892 "c:\program files\winboard.exe" /ics /icshost=localhost /icsport=5000
895 <p>After you get this working, you can try getting the timestamp window to
896 auto-minimize by starting it from a shortcut instead of from the
897 SocksCap32 control window. As it says in the SocksCap32 help file, put
898 the following in the Target field of a shortcut's Properties page:</p>
901 "c:\program files\sockscap32\sc32.exe" timestamp
904 <p>Then select "Run: Minimized" on the same page. Do the same for timeseal.</p>
906 <p>Another method that can work is to use a .bat file to start both
907 timestamp and WinBoard. It would look something like this:</p>
912 REM -- Start timestamp under SocksCap32 and use WinBoard to connect to it.
913 REM -- The string "timestamp" refers to a SocksCap32 profile for timestamp.
914 REM -- Do not change it to the filename of the timestamp program!
916 start /minimized "c:\program files\sockscap32\sc32.exe" timestamp
917 cd "c:\program files\winboard"
918 winboard /ics /icshost=localhost /icsport=5000
921 <p>This workaround has a problem if you want to run two copies of
922 WinBoard at once, talking to the same chess server twice (for
923 bughouse) or to two different chess servers. If you need to do that,
924 you will need to run a separate copy of timestamp with <i>a different
925 port number</i> for each connection. You'll need to make a second set of
926 profile entries with a different value after the -p flag (say, 5001)
927 and you'll need to change the WinBoard command line /icsport=5000 for
928 the second WinBoard to match.</p>

985 Can I get Zippy to automatically reconnect to ICS when its connection
988 <p>There isn't a perfect solution to this problem yet, but a pretty
989 good one is to write a shell script (for xboard) or .bat script (for
990 WinBoard) that automatically restarts the program whenever it exits.
991 Use the -xexit flag so that you don't get a popup dialog that must be
992 dismissed with the OK button before the program will exit. The gap in
993 this solution is that your connection to ICS can sometimes get into a
994 state where the program does not notice that the connection is broken
995 until the next time it tries to send a command. Perhaps some future
996 version of xboard/WinBoard will have an option to send a harmless
997 command every five minutes or so.</p>
999 <p>Anyway, here is a sample Windows .bat file that restarts WinBoard each
1000 time it exits. Thanks to Jason Williamson. It assumes that you have put
1001 your computer account's name and password in a file named logon.ini.</p>
1006 REM -- Start WinBoard in Zippy mode, and restart it each time it exits.
1007 REM -- Add or change parameters as needed for your application.
1010 start /w winboard /zp /ics /icslogon logon.ini /xexit /xautoraise
1011 REM -- The next line is to have a short delay setup for 139 seconds.
1012 REM -- Leave it out if it doesn't work on the version of Windows you use.
1013 TYPE NUL | CHOICE.COM /N /CY /TY,99 >NUL
1017 <p>Here is a Unix shell script to do the same thing for xboard.
1018 It's a bit more elaborate. It is based on the script I use for the
1019 original Zippy. It logs all ICS output to a file named zippy.out,
1020 and it lets you type commands to Zippy by running "cat > zippy.fifo".</p>

1056 The chess engines are too strong and always beat me. How can I adjust
1057 the difficulty level to make them weaker?</a></h3>
1059 <p>The best way is to get a weaker chess engine.
1060 On the <a href="http://www.open-aurec.com/chesswar">ChessWar</a> website
1061 you will find a rating list of virtually all engines that are able to
1062 play under XBoard/WinBoard, from super-humanly strong to ridculously weak.
1063 Most of them can be downloaded for free from the internet.</p>
1065 <p>A way to get that effect is to limit the time the engine can use for
1066 deciding on its move. The time-odds options or menu items in the
1067 time-control dialog) can be used to this end. This is only of limited
1068 help, as engines do not weeken that much at faster time-control,
1069 and there is a practical limit to how fast you can order the engine
1070 to go. Also feel free to use Retract Move if
1071 you make a blunder. </p>
1073 <p>Many chess coaches will let you switch sides after
1074 they get a stronger position so that you can get experience playing
1075 positions where you are winning. You can try this with XBoard/WinBoard
1076 by using the Machine White or Machine Black menu command to make the
1077 machine take over your position.</p>
1079 <p>The -depth command-line option to XBoard/WinBoard can also be used to
1080 weaken the engine (see the man page or Help file). It's a bit of a
1081 nuisance to set command line options in Windows, but see topic <a
1082 href="#tag-C.7">[C.7]</a> for instructions.</p>
1084 <p>Other ways of weakening engines are engine-specific. Many of them
1085 let you adjust various parameters, and if you choose bad settings, the
1086 engine will play more poorly. Consult whatever documentation came with
1087 the engine you are using.</p>

1105 <h3><a name="tag-B.26">[B.26]
1106 How can I get rid of these silly logos that this new WinBoard displays above the board?</a></h3>
1108 <p>WinBoard 4.4.0 has an option /autoLogo, which makes is search for bitmap files to display as logo,
1109 in the engine directory or in the folder "logos".
1110 If you see logos without having asked for them, the settings in your winboard.ini file probably contains the line</p>
1111 <pre>/autoLogo=true</pre>
1112 <p>Just change that to /autoLogo=false.
1113 You can also achieve that by starting WinBoard through the startup dialog (from the start menu),
1114 and then tick "additional options" at the bottom,
1115 and type /autoLogo=false in the edit field, before pressing OK.
1116 If you then later select "Save Settings Now" from the Option menu,
1117 or when "Save Settings on Exit" is on, and you close WinBoard,
1118 this will automatically end up in your settings field.
1120 When /autoLogo=false, logos will only be displayed if you explicitly ask for them,
1121 by running WinBoard with the option /firstLogo=FILENAME.bmp or /secondLogo=FILENAME.bmp.
1122 (Which will not be stored in the winboard.ini,
1123 but might of course be hidden somewhere in a settings file mentioned on the command line as @SETTINGSFILE.ini.)
1127 <h3><a name="tag-B.27">[B.27]
1128 How can I install logos for other engines, Internet Chess Servers or Human users?</a></h3>
1130 <p>With the option /autoLogo=true, (which is remembered in your settings file),
1131 WinBoard automatically looks into the engine folder
1132 (specified by the /fd="..." or /sd="..." option), for a file called "logo.bmp".
1133 If it is found, it is used as a logo for the engine when it plays.
1134 So all you have to do is put a logo.bmp file there.
1135 Popular logo formats are 100x50 and 130x65; many engine logos are available from
1136 <a href="http://www.geocities.com/davedahlem/my_logos.html">David Dahlem</a> or
1137 <a href="http://kirill-kryukov.com/chess/discussion-board/viewtopic.php?t=545&f=7">Graham Banks</a>
1139 It is possible to overrule the /autoLogo by explicitly using a /firstLogo="FILENAME.bmp"
1140 or /secondLogo="FILENAME.bmp" with the engine on the engine line in the startup dialog.
1141 This is useful for engines that run with an adapter like Polyglot,
1142 when you have only one polyglot on your system, used by many engines.
1143 E.g. for Fruit the engine line to be typed in or selected from the combo box is
1145 "polyglot fruit.ini" /firstLogo="D:\Engines\Fruit\logo.bmp" /fd="D:\Engines\Polyglot"
1147 This prevents WinBoard looking for the logo in the Polyglot folder.
1149 For Internet Chess Servers and Human users the logos should be in the "logos"
1150 sub-folder of the folder where WinBoard is installed.
1151 With /autoLogo=true, WinBoard would look for a logo file in that folder with
1152 the same name as the ICS, suffixed with .bmp (e.g. freechess.org.bmp)
1153 or the Human username
1154 (specified by the /userName="..." option or taken from the system),
1155 suffixed by .bmp, e.g. administrator.bmp)

1183 <p>If you have the Xaw header files installed in a different place
1184 than the other X11 headers, you may need to configure XBoard with an
1185 extra flag to help it find them. For example, if yours are in
1186 /foo/bar/X11/Xaw, try this:</p>
1190 (setenv CFLAGS -I/foo/bar ; configure)

1196 <h3><a name="tag-C.2">[C.2] Configuring or building XBoard fails due to
1197 missing header files, missing libraries, or undefined symbols.
1200 <p>Perhaps you have the X server and client programs installed on your
1201 machine, but not the X header files and link-time libraries. If so,
1202 you can run existing X programs, but you cannot compile a new X
1203 program from source code. In this case the XBoard configure script
1204 will fail and will tell you to look at this question in the FAQ. Many
1205 GNU/Linux distributions put the headers and libraries in a separate
1206 package, which you might not have installed. If you are using RedHat,
1207 install the XFree86-devel package. If you are using some other
1208 kind of Unix, ask your system administrator where to find the X header
1209 files and link-time libraries. If this is not your problem, read on.</p>
1211 <p>The configure script for XBoard looks for X libraries and header
1212 files in some common places. Sometimes it fails: If yours are
1213 installed in an odd place, it may not find them at all. If you have
1214 more than one version of X installed on your system, it may find the
1215 "wrong" one, or occasionally it may find libraries from one version
1216 and incompatible header files from another. You can work around these
1217 problems by telling the configure script where the files are. For
1221 configure --x-includes=/odd/place/include \
1222 --x-libraries=/odd/place/lib
1225 <p>The directory named in the argument to --x-includes must have a

1227 your X.h file has full pathname /odd/place/X11R6/include/X11/X.h, then
1228 you must give the argument --x-includes=/odd/place/X11R6/include.</p>
1230 <p>Some linkers have bugs that cause bogus error messages when you try
1231 to link X programs. The configure script includes a workaround for a

1243 <hr /><h3><a name="tag-C.3">[C.3] I have problems using WinBoard on ICS
1244 with a modem. I'm not running SLIP or PPP, but just dialing in to an
1245 ordinary login account ("shell account").</a></h3>
1247 <p>Here are solutions to some common problems in this area.</p>
1249 <p>Some people want to connect to ICS through HyperTerminal or some other
1250 terminal program first, then run WinBoard. This is not how it works.
1251 WinBoard wants to talk directly with your modem, acting as a terminal program
1252 itself. Start out with the modem "on hook" (not making a call).</p>
1254 <p>Run WinBoard with a command line like this (adding more options if desired):</p>
1257 WinBoard /ics /icscom com1
1260 <p>Use com2, com3, or com4 in place of com1 if your modem is connected to one of those ports.</p>
1262 <p>After you start WinBoard, you may need to change some of the options in the
1263 Communications dialog (on the Options menu). The dialog has the usual options
1264 for talking to modems: bits per second, bits per byte, parity, number of stop
1265 bits. You will probably want to use Save Settings Now when you're done.</p>
1267 <p>Next, type dialing commands to your modem in the text window that WinBoard
1268 creates. You may need to turn off Local Line Editing on the Options menu
1269 while you are typing commands to your modem. Turn it back on when you're
1270 done. See the WinBoard Help file for instructions if you see your typing
1271 echoed an extra time after you hit Enter.</p>

1275 I have problems using WinBoard on ICS with Windows 95 and SLIP
1276 or PPP. When trying to start up, it gets the error "Address family
1277 not supported by protocol family" (or some equally strange message).
1280 <p>WinBoard is a 32-bit application, but some Winsock (TCP/IP) implementations
1281 support only 16-bit applications. You get a strange looking error message
1282 if you try to use a 32-bit application because
1283 there is no standard Winsock error code number
1284 for "32-bit application not supported."</p>
1286 <p>Microsoft TCP/IP works with both 16-bit and
1287 32-bit applications, supports SLIP, PPP, Ethernet, etc., and is included
1288 with Windows 95 and later Windows systems.
1289 If possible, I recommend that you uninstall
1290 whatever Winsock you are using and install Microsoft TCP/IP instead.

1296 <p>Trumpet Winsock 2.1 (and earlier) supports only 16-bit
1297 applications, and hence does not work with WinBoard. But there is a
1298 beta-test release available that does support 32-bit applications.
1299 I have not tried it with WinBoard, but it

1303 >http://www.trumpet.com.au/wsk/winsock.htm</a>
1304 for more information.</p>
1306 <p>The 16-bit versions of America On-Line's software do not support
1307 32-bit Winsock applications. Get the 32-bit version. At one time the
1308 32-bit version was called "AOL for Windows 95," but I imagine that has
1309 changed. Hopefully the current versions are all 32-bit.</p>
1311 <p>A few versions of Winsock may have bugs that prevent
1312 Windows timestamp/timeseal from working with them. I'm not sure if
1313 such bugs exist in any versions that actually have 32-bit support,
1314 so this point might be moot. Again, Microsoft TCP/IP is known to work.</p>

1485 and the ICS host name (for example,

1493 gnome-terminal, all of which seem to work fine. In fact, current
1494 versions of kterm and konsole seem to work fine too, so if you are

1731 get the error message "Failed to start first chess program fairymax
1732 on localhost: fairymax: No such file or directory."</p>
1734 <p>If you have GNU Chess 5, the command should be "gnuchess xboard"
1735 instead. To make XBoard use this command, give the -fcp parameter
1739 xboard -fcp "gnuchess xboard"
1742 If you instaled GNU Chess as a package, the operating system usually
1743 knows where to find it, and GNU Chess knwos where to find its data
1744 files, such as the opening book.
1745 If GNU Chess is installed in a non-compliant way, e.g. together
1746 with its book file in a user directory, you must use:
1749 xboard -fd <I>gnuchess_directory</I> -fcp "./gnuchess xboard"
1752 <p>Here <I>gnuchess_directory</I> is the directory where you installed
1753 GNU Chess 5 and its book.
1754 In all cases you can add more xboard options at the end of the command
1757 <p>If you want to use GNU Chess 4, the command should be "gnuchessx"
1758 instead. To make XBoard use this command, give the -fcp parameter
1762 xboard -fcp "gnuchessx"
1765 <p>The same applies for non-compliant installs as for GNU Chess 5:
1766 the install directory has to be given with the -fd argument. </p>
1769 <h3><a name="tag-D.7">[D.7] How do I use GNU Chess with WinBoard?</a></h3>
1771 <p>Well, why would you want to? If you want a strong free engine,
1772 use Crafty, Glaurung, Fruit or Toga.
1773 If you wnt an engine that plays many variants, use Fairy-Max,
1775 But the procedure to install and run those is not any different than
1778 <p>If you want to use a WinBoard-compatible chess engine that is not
1779 automatically installed with the download,
1780 you will have to download it yourself.
1781 Most chess engines are downloaded as a compressed archive (e.g. a .zip file),
1782 and on downloadig it, the decompression software on your Windows system
1783 is automatically invoked when you seected "Open" in the download dialog.
1784 You can then click "extract all files", and you are prompted for a place
1785 to put the unpacked stuff.
1786 The place it proposes is usually no good, so browse to the folder
1787 in which you installed the winBoard download
1788 (where you see the Fairy-Max and WinBoard folders).
1790 When the archiv contained a single folder, (with files in it),
1792 If the archive contained a lot of small files, first create a folder,
1793 and browse there, before you unpack.
1794 (To get all the files in a single place, not mixed with others,
1795 so you can easily delete it again.)
1796 Say you unpacked in a folder named "NewEngine", which now sits
1797 next to your "WinBoard" folder amongst the chess files on your system.
1798 Say there is a file "Engine.exe" in this "NewEngine" folder.
1800 Then to run the engine with WinBoard,
1801 you have to enter the command:
1804 winboard /fcp="Engine.exe" /fd="..\NewEngine"
1807 Sometimes engines need parameters on their command line,
1808 e.g. to set the hash-table size, or tell them they have to
1810 These should then go within the quotes around the Engine.exe file name,
1811 directly behind it, and separated from it (and each other) by spaces.
1812 See any README files that come with the engine to learn how
1813 exactly the engine has to be invoked.

1819 you don't need to be a super GM to still have a chance to beat it.

1821 such as Capablanca or Gothic Chess, Knightmate, etc.
1822 Dedicated versions of it are available to play Shatranj and Xiangqi
1827 <h3><a name="tag-D.9">[D.9] What is UCI? What is Polyglot?</a></h3>
1829 <p>UCI, or Universal Chess Interface, is a standard for communication
1830 between chess engines and its Graphical User Interface, that was
1831 created as an alternative to the way XBoard / WinBoard does it.
1832 (The latter way having become known as
1833 "<a href="#tag-B.17">WinBoard protocol</a>").
1834 XBoard / WinBoard do not understand a word of UCI,
1835 so UCI engines cannnot be run directly as engine under them.
1837 Polyglot is an adapter that translates WB protocol to UCI.
1838 It bhaves like it is a WB engine, but, without XBoard / WinBoard
1839 knowing about this, it consults an UCI engine for getting the moves.
1840 With the aid of Polyglot, any UCI engine can be run under WinBoard.
1841 Polyglot is available as a Debian package for Linux, and is included
1842 in the WinBoard installation.
1843 Polyglot is open source software released under the GPL.
1847 <h3><a name="tag-D.10">[D.10] How can I run a UCI engine under XBoard / WinBoard?</a></h3>
1849 <p>First you have to download and install the UCI engine.
1850 This is similar to installing WinBoard engines,
1851 see <a href="#tag-D.7">D.7</a>.
1852 Furthermore, you have to make sure that
1853 <a href="#tag-D.9">Polyglot</a> is nstalled on
1854 your system, in a place where XBoard / WinBoard can find it.
1855 There are then two ways to run the UCI engine:
1857 In the first method, the only thing you have to do is add an extra
1858 option to the command that invokes XBoard / WinBoard,
1859 to tell it that the engine is UCI:
1862 xboard -fcp "fruit" -fUCI
1864 winboard /fcp="Fruit_21.exe" /fd="..\Fruit" /fUCI
1867 The second method is more complicated, but also more versatile.
1868 UCI engines accept many settings from their GUI than XBoard / WinBoard
1869 usually send to a WB engine.
1870 Polyglot can provide such settings from a file dedicated to that engine,
1871 usully referred to as a "polyglot.ini" file (although the actual name
1873 If the engine you downloaded comes with a polyglot.ini file for it,
1874 you can force Polyglot to use this file with engine settings
1875 by invoking it explicitly from XBoard / WinBoard:
1878 xboard -fcp "polyglot INIFILE"
1880 winboard /fcp="polyglot INIFILE" /fd="POLYGLOTDIR"
1883 INIFILE is the name of the polyglot.ini file (possibly a path name,
1884 such as "PG\fruit.ini", while POLYGLOTDIR should be the directory
1885 (path) name were the Polyglot executable is located.
1886 The directory and name of the actual engine are described in the
1887 polygot.ini file, and XBoard / WinBoard need not be aware of them.
1889 If you don't have a polyglot.ini file for the engine, you would
