Scid vs. PC

Chess Database


Shane's Chess Information Database is a powerful Chess Toolkit, with which one can create huge databases, run chess engines, and play casual games against the computer or online with the Free Internet Chess Server. It was originally written by Shane Hudson , and has received strong contribution from Pascal Georges and others.

Scid vs. PC began with bug-fixes for the computer-versus-player features of Scid (hence the name), but has evolved into a solid alternative with many new features and interfaces. The project is authored by Stevenaaus and numerous contributors (thanks).

4. Installation

Linux , FreeBSD

Scid vs. PC requires Wish (Tcl/Tk) 8.5 or later (though 8.5.10 has nasty bugs and should be avoided), and a C++ compiler .
Example packages required include "tcl, tk, tcl-devel, tk-devel" and "gcc-c++ , libstdc++"; but of course will vary with your distribution.

Extra chess pieces (such as Berlin) are now enabled by default for Wish 8.6, but 8.5 requires installing TkImg. Sound support requires Snack.
If your distro does not provide these packages ("tkimg", "tcl-snack"), you can install from source using these links (both of which have fixes applied).
TkImg, Snack.

Then, installing from source:

tar -xzf scid_vs_pc-4.13.tgz
cd scid_vs_pc-4.13
sudo make install

It is also possible to install Scid vs. PC into /usr, instead of the normal /usr/local. This allows for parallel installation with mainline Scid, and is done by: ./configure BINDIR=/usr/bin/ SHAREDIR=/usr/share/scid/

Debian / Mint / Ubuntu users may be interested in this link.


Windows installation simply requires downloading the executable, and following the prompts.

The configuration files, including the chess engine list, are stored in the Scid vs PC\bin\config directory, and may be copied over from old versions to make upgrading easier. On Windows 7, these files are mirrored in C:\Users\[USERNAME]\AppData\Local\VirtualStore\Program Files\Scid vs PC

Mac OS X

The ScidvsMac-4.13 app in the downloads section should include everything you need. Simply drag and drop the App into /Applications (or similar).

Note: Users upgrading may have to remove (or edit) $HOME/.scidvspc/config/engines.dat

To compile from source - once you have XCode installed - please read ScidvsMac-HowTo.rtfd in the source tarball.

OS X's Cocoa port of Wish is broken, with little chance of repair. Scid vs PC ships with a custom 32bit Carbon build of Wish.

5. News

April, 2013

Finally have a docked windows feature. It's a damn complicated thing, but i am fond of it.

September, 2012

I've been messing with OS X and noticed an issue with the 4.8 build - which was made on Snow Leopard. Luckily i've kepy my OS X 10.5 around, and have made a new build with it (which also includes PPC support). Macs are lovely things .... when they work.

March, 2012

Big effort by Gregor to write Drag and Drop support for Scidb and ScidvsPC ! Thanks. FICS is looking great too.

February 14, 2012

4.7 is out and includes tree bar-graphs, and the ability to observe multiple games in FICS.

September 29, 2011

Jiri Pavlovsky has made a windows installer. It's a nice piece of software :) Big thank-you. And we now have undo and redo features.

July 8, 2011

Thanks to Gilles for the web page restructure and OS X testing. Gregor Cramer has contributed a PGN figurine feature.

April 19, 2011

A belated thanks to Lee from Sourceforge for this article.

December 10, 2010

July 3, 2010

For the tenth release I've adopted verison number 4.0 . It includes a new Computer Tournament feature (thanks to some UCI snippets from Fulvio) and the Gamelist Widget is finally up-to-speed for large databases.

April 19, 2010

Release includes a Fics accept/decline offers widget.

December 20, 2009

Thanks to Dorothy for making me a Mac DMG package with this release ,

August 16, 2009

With I've fixed Phalanx's illegal castling. There is also changes to the Setup board and Toolbar configuration widgets.

July 17, 2009 - New Gamelist widget, and re-fashioned main buttons. Project's looking quite solid :->

June 23, 2009

The monkey on my back has really been having a good time. This release includes changes to the Gameinfo, Comment Editor, and Board Style widgets, some new chess pieces, colour schemes and tiles. Thanks to Michal and Alex for feedback.

June 4, 2009

Well, the html is up, and i've got a couple of files in the downloads section. My project is fairly modest fork of Scid ... just rewriting Tk widgets when i get the urge.

6. Miscellaneous

6.1 docked windows

Docked Windows allows one to arrange many of Scid's sub-windows as tiles and tabs in a single toplevel. Rearranging of windows takes a little practice, but there are two methods. Grabbing the windows tab , one can drag and drop them over other window's tabs. Alternatively, right-clicking on the tab displays a menu from where one can dislodge them relative to the current window. Right-clicking the main board shows a menu for hiding various parts of the window.

There are a few associated options for this feature in Options->Windows. Deselecting "Dock Windows" will prompt one to exit and when restarted, the docked windows feature will be disabled.

However, it does have a few issues:

  • Tcl/Tk 8.6.0 may have bugs.
  • Key bindings (especially menus) can be hit and miss.
  • Windows undocked from within docking mode can have glitches. Mainly: drag and drop game copies in the switcher don't work.
  • OS X support is not good.

In the event of problems, start the program with the "-nodock" command-line option to disable docking.

6.2 how to play

Playing against the Computer

The main Computer vs. Player feature is accessed from Play->Computer. Here you'll find options to play against Phalanx (a flexible computer opponent whose skill you can select), or any installed UCI engine.

Playing on the Internet

Playing on the Internet is done via the the Play->Internet menu item. I recommend visiting the Fics website to create a user account, but it is also possible to play anonymously. To start a game, press the Login as Guest button, then watch the available games as they are announced in the console. Enter play [game number] to accept a game challenge.

There is more information about the Fics and Computer Game features in the online documentation.

6.3 todo

  • Openseal is an open source version of FICS Timeseal. It needs some rewriting to work with Scid, though it is a small program.
  • FICS could be adapted to work with the ICC. The work involves analysing the differences in the strings used by the two programs. (for example, for FICS we have this line to ackowledge successful log-in if {string match "*Starting FICS session*" $line]} { The two servers do have many similarities i think, and examining xboard's "backend.c" (or some other client) for "FICS" particularities
  • Translation updates
  • The TCL sound package, Snack, needs a maintainer.
  • There was a lot of work done to implement Fischer Chess (Chess 960), but they never fixed all the bugs, and the web site is now gone. The latest code is in ScidvsPC's source patches/chess960.patch
  • The Tree code works reasonably well, but i have never found the time to overhaul the Slow/Fast/Slow modes. These were (for a long time) negelected when Fulvio wrote the interuptible tree code. Scid now has the Modes removed, so doing this in ScidvsPC probably wouldnt be terribly hard to do.
  • There are two engine types - UCI and XBoard. Pascal's UCI code is in some ways inferior to Shane's Xboard code. Though this is mostly mitigated by the speed of modern processors, it'd be nice to make use of the UCI ponder feature in analysis mode (Comp mode already does so).
  • I've never had a chance to verify/update the Novag Citrine drivers and interface due to lack of hardware.
  • Our Windows port needs a little overhaul to properly use Users home directory to store all the various data. I will get around to doing it one day though.
  • A lot of people use chessbase books (.ctg). Scid can only read polyglot opening books, but inlining this projects work may not be too hard.

6.4 known issues

  • Tcl/Tk-8.5.10 is buggy.
  • OS X docked mode has some issues due to it's poor Tcl/Tk.
  • Focus Issues. Kde users can allow Tcl apps to properly raise themselves by configuring desktop > window behavior > advanced > focus stealing prevention set to "none"

6.5 bugs

  • See the known issues about Tcl/Tk (above).
  • Importing huge PGN archives can sometimes fail. The command line utility pgnscid is a more reliable way to create large databases from pgn. Typing "pgnscid somefile.pgn" creates a new database "somefile.si4".
  • Using the '+' operator and clicking on 'Find' in the gamelist widget can be very slow. The code needs to be moved from gamelist.tcl to tkscid.cpp.
  • Windows only:
    • Using "ALT+F"... etc key bindings to access the menus is badly broke. This is a Tcl/Tk issue.
    • Window focus/raise issues, another Tcl/Tk issue.

6.6 thanks

Thanks to Shane Hudson and the authors of Tcl/Tk. To Gregor Cramer for new features and technical support. for their great hosting, Jiri Pavlovsky for the windows installer. Thanks to Pascal Georges for his many technical contributions to mainline Scid, and also Fulvio, Gerd and the language translators. To Gilles, Dorothy and Steve for OS X support, to Michal Rudolf for early encouragement, and H.G.Muller for technical feedback.

6.7 scid's history

Scid is a huge project, with an interesting history. Originally authored by Shane Hudson from New Zealand, it combined the power of Tk's GUI and the speed of C, to produce a free Chess Database application with Opening Reports, Tree Analysis, and Tablebase support. It gained quite some attention, as it was arguably the first project of it's kind; but after writing over a hundred thousand lines of code, in 2004 development stopped and Shane never contributed to Scid again.

Two new versions of Scid appeared around 2006. The first was ChessDB authored by Dr. David Kirby. With some good documentation and the ability to automatically download games from several web portals, it became popular. But at the same time Pascal Georges from France was making strong technical improvements to Scid. Frustrated with Scid's dormancy, and because of disagreements with ChessDB's author, Pascal released his own tree, Scid-pg, which included UCI support and numerous Player versus Computer features.

But subtley, and with some controversy, he began to adopt the name Scid as his own. Some people objected, especially Dr. Kirby, with whom a flame war began, but Pascal's efforts to gain ownership of the Sourceforge Scid project eventually succeeded.

Under Pascal, and with the help of numerous contributors, Scid again strode forward. Pascal wrote a Tree Mask feature, and in 2009 he upgraded the database format to si4, all the time making speed and technical improvements to the neglect of the interface. In 2010, Pascal ceased contributing at all, and shortly after Scid 4.3 was released. Since then, Scid has had widespread technical changes by Fulvio Benini, who is a long-standing contributor.

Currently there exist several Scid related projects.

Chessx was originally by Michal Rudolf (a longtime Scid contributor from Germany) and named Newscid. Now led by Jens Nissen, with a 1.0 release, it is an attractive Chess GUI but with a small feature set and without si4 support.

Scid vs. PC was started in 2009 by Steven Atkinson from Australia. Forked from Scid-3.6.26, it began as an effort to tidy Shane's frenetic code base and improve the user interface, and has since matured into a capable Scid successor.

The Android program, Scid on the Go, supports the si4 database format, and is the only mobile Scid related project.

Another project nearing a 1.0 release is Scidb by Gregor Cramer from Germany. It is an ambitious chess database program inspired by Scid, with heavy utilization of C++ classes and customized Tk widgets. It also supports Chessbase databases and many chess variants.
