ExaChess is a powerful chess-database program for the Macintosh with many features. Use it to manage a database of hundreds of thousands of master games, as a chessboard to play through games, as a tool to record and annotate your own games, to play games against the computer, or to play perfect endgames.
ExaChess Lite is a freeware version of ExaChess which provides most of the features of ExaChess in a version suitable for maintaining a personal games collection.
ExaChess 1.1 is an upgrade of ExaChess 1.0 which adds several major features and numerous minor feature tweaks and bug fixes. If you are a user of ExaChess 1.0 or ExaChess Lite 1.0, see the file 'Release Notes 1.1' for information on what's changed and how to upgrade to 1.1.
To order ExaChess 1.1, see the section How to order ExaChess 1.1 at the end of this file.

How to install ExaChess
The ExaChess application needs two folders alongside it: ExaChess Games and ExaChess Tools. The first of these holds databases (in ExaChess, ChessBase, NICBase, Text, PGN or EPD format) and individual game files.
To install your own databases, drag them to the ExaChess Games folder to supplement the ones supplied. You can create subfolders (one level only) within the ExaChess Games folder; these show as hierarchical menus in the ExaChess Games menu.
The Tools folder contains the Help file, the Opening Key file(s), and the external chess engines such as ZZZZZZ. Leave these files in the Tools folder.
On-line help
ExaChess has comprehensive on-line help available; choose Help from the Windows or Help (Balloon) menu. Balloon help is available for menu items and toolbar icons; turn it on using the Help menu. The Help file is an eDOC™ self-running application that can be printed to give a high quality User's Guide for ExaChess.
The Databases
ExaChess Lite and ExaChess come with 7 and 9 sample databases in the ExaChess Games folder respectively. The three Linares databases are found in the Linares subfolder:
Famous games (ExaChess format)
— a collection of 44 famous or spectacular games across the ages.
King's Indian Samisch (ExaChess format)
— 240 games featuring the King's Indian Samisch variation. This database has an Opening Tree index for demonstrating the Show Opening Tree feature: Open this database or select it in the All Databases window, then open a new game and select Show Opening Tree.
Linares93.cbf (ChessBase™ format, macified)
— 91 games by super-Grandmasters from the 1993 Linares tournament.
Linares94.g30 (NICBase format, macified)
— 106 games by super-Grandmasters from the 1994 Linares tournament.
Linares95.pgn (PGN format)
— 91 games by super-Grandmasters from the 1995 Linares tournament.
Max endgames (ExaChess format — ExaChess (Pro) only)
— 102 games generated by computer of the longest winning lines for various 5-piece endgames, from KNN v KQ (won in 1 move) to KQP-KQ (118 moves). The games come from Ken Thompson’s endgame CD-ROMs.
Win At Chess 250 (ExaChess format)
— 250 problems with solutions taken from the book Win At Chess.
WorldCh (ExaChess format — ExaChess (Pro) only)
— All 905 games played in World championship matches from Steinitz-Zuckertort 1886 to Karpov-Kamsky 1996.
~Bratko-Kopec.epd (EPD format)
— 24 problems with solutions, devised by D. Kopec and I. Bratko, "The Bratko-Kopec Experiment: A Comparison of Human and Computer Performance in Chess", 1982, and now a common computer test.
ExaChess (Pro) optionally comes with 5 additional databases on Disks 2 to 6. These provide a starter database of around 70,000 games, and are installed simply by copying them into the ExaChess Games folder. The databases take up approximately 7 MB and will need a further 7 MB when fully indexed. To squeeze more games onto the disks, the databases are provided unindexed. To build their indexes: install the databases, choose All Databases from the Windows menu, select the databases from the database list in the window, and choose Rebuild Index from the Database menu. You may wish to do this as an overnight job if you have a slower Mac. The databases are all in ExaChess format and are:
Pre-1950 games
1950-79 games
1980-89 games
1990-93 games
1994-96 games
Tools
The ExaChess Tools folder contains several files used by ExaChess Lite and ExaChess:
ExaChess Help
— This is the help file for ExaChess. It is a comprehensive User Guide to ExaChess in the form of a self-reading eDOC™ document. Print it out to produce a printed manual.
Format.rtf (ExaChess (Pro) only)
— This file is a Rich Text Format (RTF) definition of the format used by ExaChess when it exports one or more games in RTF format for print publication.
Opening Key
— This file is used to classify openings and supply opening names. ExaChess (Pro) comes with the additional files Opening Extn and Opening Names which contain transposition lines and the definitions of the opening names. Put an alias of Opening Names into the ExaChess Games folder for easy access to these definitions.
ZZZZZZ
— This is a chess playing program by Gijbert Wiesenekker (wiesenecker@sara.nl), modified to handle the Apple Event suite used by ExaChess for communicating with external chess engines. ZZZZZZ has a simple text-based user interface, but can be controlled by ExaChess so that you need never use the text interface. The file ZZZZZZ.ReadMe contains more information about ZZZZZZ, and the files zzbook.w and zzbook.b contain its opening book. See the on-line help under Computer Play for information on how to drive ZZZZZZ or any other chess engine from within ExaChess. ZZZZZZ is set to make its moves within 15 seconds. ExaChess will launch or quit it as required. It is a fat binary.
Utilities (ExaChess (Pro) only)
— The Utilities folder contains two utilities that may be useful. CBSplitter can be used to split a very large ChessBase™ database into smaller chunks more easily handled by ExaChess. ExaResForkKiller can be used to remove the resource fork (the index) of ExaChess databases, as described under Recovery in the on-line help.
Chess Fonts
ExaChess (but not ExaChess Lite) supports publication of chess games including annotations, diagrams, and figurines, as RTF files for import into page layout or word processing programs. To include diagrams or figurines in printed diagrams, you need a Postscript or TrueType chess font. ExaChess does not include such a chess font; you need to obtain one from a third party.
Several vendors sell high quality chess fonts suitable for use with ExaChess. The fonts sold by Alpine Electronics are highly recommended:
Alpine Electronics sells a variety of TrueType and PostScript chess fonts for both Windows or Macintosh computers. They can be used to create chess diagrams with six different borders and algebraic figurine notation with the complete set of Informant and New-In-Chess annotation symbols. There are three main styles or font families -- Linares, Hastings and Zurich. Each font family also includes rotated pieces for chess variants and one style of checker pieces.
Each chess font family (Linares, Hastings or Zurich) includes many different keymap versions (over one megabyte of chess fonts) in both TrueType and PostScript formats and a nice 14 page User's Guide. The cost for one font family is $29, two font families cost $49 and all three are $59 postpaid (airmail shipping to non-US addresses is extra). All of the fonts have a 30-day unconditional money back guarantee.
Linares is an American style chess font. Many chess books have been published with the Linares fonts. Hastings is a font based on an older ornate chess font (the brick work on the rooks is visible for example). Several chess books have been published with the Hastings fonts. Zurich is European style chess font similar to the font used by New-In-Chess or the British Chess Magazine.
If you want to order the fonts, specify Windows or Macintosh and send a check or MasterCard/Visa number, expiration date and name as it appears on the card to: Alpine Electronics, 526 West 7th St., Powell, WY 82435, USA. For overseas orders add $3 for airmail postage for each font and send either a check drawn from a US bank or an international money order or a MasterCard/Visa number, expiration date and name as it appears on the card.

Compatibility Issues
• Some users have had trouble opening PGN databases with ExaChess. This is invariably due to those users having used Netscape to download the PGN databases. There is a bug in Netscape (version 1.1N at least) which causes it to save text files with Unix-style line endings (linefeeds) rather than Mac line endings (returns). You can see the linefeed characters with most text editors, where they show as boxes. If you convert the text file to a true Mac text file, ExaChess will handle it correctly.
• ExaChess may crash when used with SuperBoomerang 3 or Shortcut. The problems occur when ExaChess uses the System 7 routine ‘StandardGetFile’. You can avoid these problems by leaving the checkbox ‘Use StandardGetFile’ unchecked in ExaChess’s General Preferences.
• There have been reports of crashes with type 28 errors or corrupted preferences on the original 68000 Macs (SE, Classic) often when opening text or PGN games. ExaChess handles System 6, non-color Macs, and 68000 Macs, but perhaps not the combination of all three.
• Database files whose name begins with a period can cause crashes. Do not use filenames starting with a period.
