It displays a chessboard on the screen, accepts moves made with the mouse, and loads and saves games in Portable Game Notation (PGN). It serves as a front-end for many different chess services, including:</p> <ul> <li> Chess engines that will run on your machine and play a game against you or help you analyze, such as GNU Chess, Crafty, or many others.</li> <li>Chess servers 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.</li> <li>Correspondence chess played by electronic mail. The CMail program 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.</li> </ul> <p>XBoard runs on Unix and Unix-like systems that use the X Window System. </p> <div class="examples"> <div class="left"> <img src="whats_new/SpartanGTK.png" alt=" [XBoard - chess variant] " /> <p><i>XBoard GTK build, playing some Chess variant</i></p> </div> <div class="right"> <img src="whats_new/4.4.0/marble.png" alt=" [WinBoard - marble board] " /> <p><i>WinBoard, configured with marble board</i></p> </div> </div> <h3>More...</h3> <ul class="columns"> <li><a href="#tag-A1">WinBoard</a> (MS Windows port)</li> <li><a href="#download">Downloading</a></li> <li><a href="#tag-A4">Documentation</a></li> <li><a href="user_guide/UserGuide.html">On-line User Guide</a></li> <li><a href="#tag-A5">More Screenshots</a></li> <li><a href="whats_new/4.9.0/index.html">What's New in 4.9.0?</a> (stable)</li> <li><a href="whats_new/4.8.0/index.html">What's New in 4.8.0?</a></li> <li><a href="whats_new/4.7.3/index.html">What's New in 4.7.3?</a></li> <li><a href="whats_new/4.7.2/index.html">What's New in 4.7.2?</a></li> <li><a href="whats_new/4.7.1/index.html">What's New in 4.7.1?</a></li> <li><a href="whats_new/4.7.0/index.html">What's New in 4.7.0?</a></li> <li><a href="whats_new/4.6.2/index.html">What's New in 4.6.2?</a></li> <li><a href="whats_new/4.6.1/index.html">What's New in 4.6.1?</a> (faulty)</li> <li><a href="whats_new/4.6.0/index.html">What's New in 4.6.0?</a></li> <li><a href="whats_new/4.5.3/index.html">What's New in 4.5.3?</a></li> <li><a href="whats_new/4.5.2/index.html">What's New in 4.5.2?</a></li> <li><a href="whats_new/4.5.1/index.html">What's New in 4.5.1?</a></li> <li><a href="whats_new/4.5.0/index.html">What's New in 4.5.0?</a></li> <li><a href="whats_new/4.4.0/index.html">What's New in 4.4.x?</a></li> <li><a href="#tag-A3">How can you help us?</a></li> <li><a href="FAQ.html">Frequently Asked Questions</a></li> </ul> <div style="clear:right"></div> <h3 id="tag-A1">WinBoard</h3> <p>The project also includes a port to Microsoft Windows systems called WinBoard.</p> <p>You can find the downloads for binaries and preconfigured installer packages of WinBoard at <a href="http://hgm.nubati.net/downloads.html">HGM's download page</a>.

If you want to <a href="#tag-A3">help us</a> test, or just want to use the new features, you might prefer to use those over the stable version. </p> <p>At the <a href="https://download.opensuse.org/repositories/home:/apersaud:/xboard/"> Open Build Server</a> we provide packages that can be installed in parallel to the normal xboard version. To do this the programs are renamed to xboardnext (latest from the v4.9.x branch in Git) and xboardgit (latest version from the master branch in Git). Packages are available for: Debian 6.0, Fedora 17/18, RedHat RHEL 6, openSUSE 12.1/12.2/12.3/Tumbleweed/Factory, CentOS 6, Arch, Ubuntu 10.04/12.04/12.10. These packages are generated automatically and are for testing purposes only. Please let us know if you have any problems related to XBoard or package dependencies.</p> <p> Windows builds of development versions can often be found at <a href="http://hgm.nubati.net/">HGM's web page</a>.</p> <p>Furthermore we provide development versions (tagged commits in Git):</p> <ul> <li>a snapshot of the master branch: <a href="https://alpha.gnu.org/gnu/xboard/">master-20140119</a>;</li> <li>no developer release at the moment.</li> </ul> <h5>How to build the development version</h5> <dl> <dt>Git version</dt> <dd> <p>The <a href="https://git.savannah.gnu.org/cgit/xboard.git">Git repository</a> is on Savannah.

These tarballs are different from the ones that you can download from the <a href="https://ftp.gnu.org/gnu/xboard/">GNU server</a>, and you will need to run <kbd>./autogen.sh</kbd> on them as described below.</p> <p> If you want to get a copy of the repository, you can clone it using the following command:</p> <pre class="emph-box">git clone https://git.savannah.gnu.org/r/xboard.git</pre> <p>For more information on how to use Git, please visit the <a href="https://git-scm.com/">Git home page</a>.</p> <p> After cloning the Git repository or downloading and unpacking a snapshot tarball from the Git repository, run <kbd>./autogen.sh</kbd>, <kbd>./configure</kbd>, and then <kbd>make</kbd> and <kbd>make install</kbd>.</p> </dd> <dt>Tarballs from the download server</dt> <dd> <p> Unpack the tarball and do <kbd>./configure</kbd> followed by <kbd>make</kbd> and <kbd>make install</kbd>.</p> </dd> </dl> <h4>Archive</h4> <p>You can also find an archive of old versions on <a href="https://ftp.gnu.org/old-gnu/xboard/">the FTP server</a>.</p> <h3 id="tag-A4">Documentation</h3> <p>The official <a href="manual/">manual page for XBoard</a> is available online, as is <a href="/manual/">documentation for most GNU software</a>. This discusses every feature XBoard has in detail. You may also find this information on your local system by running <kbd>info xboard</kbd> or <kbd>man xboard</kbd>, or by looking at <code>/usr/doc/xboard/</code>, <code>/usr/local/doc/xboard/</code>, or similar directories on your system.</p> <p>There now also exists an <a href="user_guide/UserGuide.html">XBoard User Guide</a>, which only presents the main features in a more pedestrian way. This would be an excellent starting point if you are a novice XBoard user. If you have prior experience with XBoard, but just want to know what new features have been added since the version you were used to, the pages in the <a href="whats_new/index.html">What's New</a> section would be the place to go. </p> <p>A description of the <a href="engine-intf.html">Chess Engine Communication Protocol</a> used by XBoard to communicate with Chess Engines is also available.</p> <h3 id="tag-A5">Screenshots</h3> <p>These are screenshots taken from version 4.4.0 (click to enlarge).</p> </div> <div class="screenshots"> <a href="graphics/xboard-4.4.0.png"><img src="graphics/xboard-4.4.0.png" alt=" [screenshot normal game] " /></a> <a href="graphics/xboard-4.4.0-variant.png"><img src="graphics/xboard-4.4.0-variant.png" alt=" [screenshot bughouse game] " /></a> <a href="graphics/xboard-4.4.0-XQ.png"><img src="graphics/xboard-4.4.0-XQ.png" alt=" [screenshot xiangqi game] " /></a> <a href="graphics/xboard-4.4.0-showgi.png"><img src="graphics/xboard-4.4.0-showgi.png" alt=" [screenshot shogi game] " /></a> <a href="graphics/xboard-4.4.0-petite.png"><img src="graphics/xboard-4.4.0-petite.png" alt=" [screenshot auxiliary windows " /></a> </div> <div class="limited-width"> <h3 id="tag-A3">Help needed</h3> <p>It would be great if people would like to help in the developing process We can use all kinds of help, from people who just use the software and have a feature request (send them to developer mailing list), to people who can update/check the documentation and especially people who test development versions (send problems to the developer mailing list). Have a look at the following list in case you are interested:</p> <h4>Admin</h4> <p>A new project admin is needed. The person would manage the Savannah pages, membership to Savannah/Git access, do releases, and manage the email list, etc. The job could also be split among several people.</p> <h4>Translators </h4> <p>We added support for different languages to XBoard and need people to translate it. The translation is handled by <a href="https://translationproject.org/html/welcome.html">the translation project</a>. You can check on the <a href="https://translationproject.org/domain/xboard.html">current status</a> and how to <a href="https://translationproject.org/html/translators.html"> join the translation project</a>. </p> <h4>Testers </h4> <p> We are always looking for people who are willing to test the latest new features and give us feedback or new ideas. If you are interested, please send an email to our list at <<a href="mailto:xboard-devel@gnu.org">xboard-devel@gnu.org</a>> or just try out the program and reports bugs either to the email list or to the bug tracker (see <a href="#download">below</a> for links).</p> <h4>GTK developer needed</h4> <p> We are also working on merging WinBoard and XBoard back into one version using a cross platform GTK-front end. This will help us clean up the code and make things like internationalization easier. We made some progress, if you know want to help out there are still lots of things waiting to be done. Email the <a href="mailto:xboard-devel@gnu.org">mailing list</a> for more information. There is already some unmerged code to port to GTK3.</p> <h4>Update the help files</h4> <p>The help files for Xboard and WinBoard could be merged into one document.</p> <h4>Update the webpage</h4> <p>The content of the webpage could be updated with screenshots from the latest version. We also have a new tutorial that could be integrated.</p> <h3>Links</h3> <ul> <li> XBoard/WinBoard <ul> <li> <a href="http://www.tim-mann.org/chess.html">Tim's original pages</a> are still available.</li> <li> XBoard can also run engines that use the UCI protocol, with the aid of the <a href="https://github.com/flok99/polyglot">Polyglot protocol adapter</a>.</li> </ul> </li> <li> Incomplete list of computer engines that work with XBoard <ul> <li><a href="/software/chess/">GNU chess</a></li> <li><a href="https://home.hccnet.nl/h.g.muller/CVfairy.html">Fairy-Max</a></li> <li><a href="http://wbec-ridderkerk.nl/html/lastupdates.htm">A list with lots of engines</a></li> <li><a href="https://home.hccnet.nl/h.g.muller/XQ.html">List of Xiangqi engines</a></li> <li> other popular engines are crafty, phalanx, fruit, toga2, glaurung, ... </li> </ul> </li> <li> Chess server you can connect to using XBoard <ul> <li> <a href="https://www.freechess.org">Free Internet Chess Server (FICS)</a></li> <li> <a href="https://www.chessclub.com/">The Internet Chess Club</a> </li> <li> <a href="http://hgm.nubati.net/VICS/">The Variant ICS</a> </li> </ul> </li> <li> Other interfaces <ul> <li> <a href="https://www.bergo.eng.br/eboard/">eboard</a> </li> </ul> </li> </ul> <h3>Frequently Asked Question (FAQ)</h3> <p>If you have any questions, please check out our <a href="FAQ.html">FAQ</a>.</p> <h3>Mailing Lists</h3> <p>XBoard has two mailing lists:</p> <ul> <li><<a href="mailto:xboard-devel@gnu.org">xboard-devel@gnu.org</a>> (<a href="https://lists.gnu.org/mailman/listinfo/xboard-devel">web interface</a>) for discussing most aspects of XBoard, including development and enhancement requests;</li> <li><<a href="mailto:bug-xboard@gnu.org">bug-xboard@gnu.org</a>> (<a href="https://lists.gnu.org/mailman/listinfo/bug-xboard">web interface</a>) for reporting bugs.</li> </ul> <p>Announcements about XBoard and most other GNU software are made on <<a href="mailto:info-gnu@gnu.org">info-gnu@gnu.org</a>>.</p> <p>To subscribe to these or any GNU mailing lists, please send an empty mail with a <i>Subject:</i> header of just "subscribe" to the relevant <i>-request</i> list.
