ChessCafe Powerbook/Turbo Endgame Installation

  1. 1. ChessCafe Powerbook/Turbo Endgame Installation CHESSCAFE POWERBOOK/TURBO ENDGAME INSTALLATION INSTRUCTIONS by Steve Lopez The Fritz chessplaying program has two peripheral items which can be purchased separately: the Fritz Powerbook and the Fritz Endgame Turbo 2. Note that the Fritz9 program is complete without these additional purchases, but both of these items add to the functionality or strength of Fritz. This article will provide a brief description for both of these products as well as installation instructions for both. WHAT IS FRITZ POWERBOOK? The Fritz Powerbook (available only on DVD) is a larger, more comprehensive opening book than the one which comes with the Fritz9 program. The "stock" Fritz9 opening book is specially tuned to maximize the strengths and avoid the weaknesses of the Fritz chessplaying engine: the program will generally tend to favor open games (at which computers excel) while avoiding closed positions (in which long-range planning is crucial, and at which computer programs have historically been weaker). The opening book which comes with Fritz9 is particularly useful for players playing computer vs. computer games and matches. The Fritz Powerbook is a much more vast opening book which pays no regard to which openings are "good" for computers to play and which are "bad"; the Powerbook covers the complete range of chess openings regardless of the open or closed characteristics of any specific opening. Consequently over the long haul use of the Powerbook will actually tend to make the program play a bit less successfully, especially in computer vs. computer contests, because the program will often play closed games. Why, then, would anyone want an opening book which tends to lessen the overall success rating of the program? Because humans like variety. The Powerbook isn't intended for use by those who are primarily pitting their Fritz engine against other chessplaying programs; Powerbook is designed for use by humans who are using Fritz to improve their playing skills and increase their own chess knowledge. Using the Powerbook will cause Fritz to play a much greater variety of openings, just as you'd see when playing against a broader range of human opponents. The Powerbook DVD actually contains two separate opening books: the full Powerbook and a second book (the "Strong" book) which is a smaller subset of the opening contained in the Powerbook proper. This second opening book contains only openings which have appeared in top-level professional chess tournaments while omitting openings such as unsound gambits file:///C|/unzipped/tb_inst/tb_inst.htm (1 of 6) [12/11/2005 11:14:50 PM]
  2. 2. ChessCafe Powerbook/Turbo Endgame Installation and other side lines which seldom appear in professional tournament play. POWERBOOK TECHNICAL CONSIDERATIONS Fritz Powerbook can be used directly from the Powerbook DVD itself. This, obviously, means that the Powerbook DVD will need to be in your computer's DVD drive instead of the Fritz9 DVD, and some Fritz features which you may not have copied to your hard drive during installation (such as the Talk files) won't be available while the Powerbook DVD is in use. Also note that the "learning" functions in Fritz (in which it will tend to favor openings at which it's been previously successful while avoiding ones at which it's previously fared poorly) won't be functional while using Powerbook directly from the DVD; these functions rely on an opening's probabilities of appearance being altered from game to game, and this information can't be written to a file located on a DVD. Consequently you may wish to copy/install the Powerbook to your hard drive, both to be able to use other Fritz functions such as the Talk feature as well as enable the Fritz program's ability to alter the probabilities of a particular opening being played. Please be aware that installing the Powerbook to your hard drive will require a fairly large amount of disk space. Installing the full Powerbook will require 1.67 GB of disk space, while installing the smaller Strong book will require a mere 67.3 MB of drive space. INSTALLING THE POWERBOOK/STRONG OPENING BOOKS Installing these opening books is best (and most easily) accomplished from within the Fritz9 program itself; note that there is no "installation wizard" program on the Powerbook DVD. To install either of these two opening books from the Powerbook DVD, please follow these instructions: 1. Insert the Powerbook DVD in your computer's DVD drive and then start the Fritz9 program. 2. In Fritz9's "splash screen" select "Play Fritz". 3. When the main chessboard screen appears, go to the File menu, select "Open", and then "Openings book" from the submenu. 4. The standard Windows File Select dialogue will appear; use this to navigate to your DVD drive. 5. When you reach your DVD drive, you'll see two opening books listed: Power2005.ctg and Strong2005.ctg -- select one of these opening books by single-clicking on it, and then click the "Open" button. The dialogue will disappear. It may appear that nothing has happened, but in reality the opening book you've selected has now been loaded. 6. To copy your selected opening book to the hard drive, go to the Edit menu, select "Openings book", and then the command "Copy tree to hard disk" from the submenu. 7. The Windows File Select dialogue will again appear and allow you to select a folder into which to store the opening book. You may use the default folder (which will be determined by your selection for same when you installed the Fritz9 program) or else navigate to another folder into which you want to copy the opening book. After you've selected a folder, click the "Save" button to start the process of physically copying the opening book to your hard drive. 8. You'll see a status bar appear which will show the installation's progress. This will take several minutes, especially for the larger Powerbook proper. The program will inform you when the installation is complete. 9. At this point I strongly urge you to exit the Fritz program. The location of the Powerbook isn't written to Fritz9's .ini file until the program is exited by the user; exiting the program at this point will ensure that the book's location will be properly remembered by the program. (In the event of a program crash or power outage before the Fritz9 program is exited normally at this point, the program won't know the location of your opening book the next time you start the program). 10. Restart the Fritz9 program, and the Powerbook or Strong book will be automatically loaded by default. DATABASE INSTALLATION file:///C|/unzipped/tb_inst/tb_inst.htm (2 of 6) [12/11/2005 11:14:50 PM]
  3. 3. ChessCafe Powerbook/Turbo Endgame Installation The Powerbook DVD also contains two databases containing the games from which the Powerbook and Strong books were derived. These databases, while not neccesary for the proper functioning of the opening books, are an interesting source of chess knowledge for you the user, and can also be installed to your hard drive or accessed directly from the DVD. If you wish to install one of these databases to your hard drive, please be aware again of the space considerations: the Powerbook database will require 206 MB of disk storage space, while the Strong database will need about 21 MB of free space on your hard drive. Note that the Strong database is a subset of the full Powerbook database; if you choose to install the Powerbook database, you won't need to install the Strong database -- the games are already contained in the larger Powerbook library of games. To install a database to your hard drive, please follow these instructions: 1. Insert the Powerbook DVD in your computer's DVD drive and then start the Fritz9 program. 2. In Fritz9's "splash screen" select "Play Fritz". 3. When the main chessboard screen appears, hit the F12 key on your keyboard to open the database window. 4. Go to the File menu, select "Open", and then "Database" from the submenu. 5. The standard Windows File Select dialogue will appear; use this to navigate to your DVD drive. 6. When you reach your DVD drive, you'll see two databases listed in the dialogue: Power2005.cbh and Strong2005.cbh -- select one of these databases by single-clicking on it, and then click the "Open" button. The dialogue will disappear and you'll see the game list for your selected database appear on the screen. 7. To copy your selected database to the hard drive, go to the Tools menu, select "Database", and then the command "Install to hard disk". 8. You'll see the following dialogue appear: You may copy the database to the default folder shown in this dialogue or else click the "Browse" button to again display the Windows File Select dialogue, which will allow you to navigate to any folder on any drive. After you've made a folder selection, click "OK" in the above dialogue to start the installation process (which will take just a few minutes). WHAT IS FRITZ ENDGAME TURBO 2? Computer chess programs have historically been weak endgame players. This is because the proper play of most endgames requires a fairly deep "lookahead" which is outside the search horizon of most chess engines. In order to provide perfect file:///C|/unzipped/tb_inst/tb_inst.htm (3 of 6) [12/11/2005 11:14:50 PM]
  4. 4. ChessCafe Powerbook/Turbo Endgame Installation endgame knowledge for the use of chess programs, a series of specialized databases called endgame tablebases was developed. The use of these tablebases greatly increases the playing strength of chess programs such as Fritz9 by giving them access to knowledge of how to play simple endgames. Tablebases are simply collections of board positions, organized by the material on the board (for example, the four piece tablebase of K+Q vs. K+R contains all possible board position combinations of these four pieces). These positions are threaded together in a logical manner, somewhat analogous to an opening tree. A computer chess program considering a particular board position of just these four pieces (you by now may have discerned that the term "piece" here includes Kings and pawns -- any piece of wood on the chessboard qualifies as a "piece" as far as tablebases are concerned) will be able to see the concrete consequences of any potential legal move (be it win, loss, or draw) as well as every exact move order leading to all of those outcomes. And chess engines can switch between tablebases when required. For example, let's say that a chess engine is consulting a database for a five-piece ending and comes across a position in which one of the pieces is captured; our five-piece ending has just become a four-piece endgame. The engine is able to switch to the proper four-piece tablebase (assuming it's available) and connect that information to that which was taken from the five-piece tablebase, thus extending its knowledge out to the game's conclusion. Futhermore the engine is able to use this information is its middlegame analysis. Let's consider a situation in which a chess engine is analyzing a late middlegame with eight pieces of wood on the board; three of them are exchanged off in one variation that the engine is considering. This has now become a five-piece ending, and the engine will be able to instantly access the information from the relevant five-piece tablebase and this extend its analysis of the late middlegame position to include all of the possible game outcomes in the variation involving the removal of those three pieces from the board. Fritz Endgame Turbo 2 is a five DVD set which includes all of these three-, four-, and five-piece tablebases, as well as a number of six-piece endings. Using the Fritz Endgame Turbo 2 will allow the Fritz9 program (as well as other ChessBase engines) to play perfect endgames. TECHNICAL CONSIDERATIONS The downside to endgame tablebases is that they are enormously consumptive of drive space. Each of the five DVDs in the Turbo Endgame set requires 4.7 GB of hard drive space to hold the data; installing all five DVDs to a hard drive will require almost 24 GB of disk space. If you intend to install any of the data to your hard disk, please be certain to check the space on your hard drive to be sure you have enough. It's certainly possible to access the smaller tablebases directly from DVD #1 (which contains all of the three-piece and four- piece tablebases, as well as the most commonly played five-piece endgames), but be aware that Fritz9 won't be able to use information from its own DVD (such as the Talk files) if this method is being used. INSTALLATION This article won't cover the myriad combinations of installation methods and possibilities for Turbo Endgame in detail; instead we'll concentrate on how to set up your Fritz9 program to use them (which will be covered later). The pamphlet which accompanies Turbo Endgame is quite clear in its descriptions of the recommended installation methods and/or partial installation combinations which the user can do. We will, however, discuss some general points which are relevant to the installation of the endgame tablebases. The tablebases are most easily installed by using the Setup.exe program which comes on each DVD. You can also manually copy just the endgames you desire by using My Computer or Windows Explorer. In either case, it's crucial that you know file:///C|/unzipped/tb_inst/tb_inst.htm (4 of 6) [12/11/2005 11:14:50 PM]
  5. 5. ChessCafe Powerbook/Turbo Endgame Installation what folder(s) you've installed or copied the tablebases into -- you must know this information later when you're setting up your Fritz9 program to use the tablebases. It's possible to use tablebases which are stored in up to four separate folder and/or drive locations; this is useful for people with partitioned hard drives (in which no single partition can hold all of the tablebase data) or users who wish to install four of the five DVDs to their hard drive and intend to access the fifth DVD directly from the DVD drive. This will be examined in more detail in the next section. If you can't install the entire set of five DVDs due to limited disk space, just install DVD #1 in its entirety (so that you'll have the basic endgames described under "Technical Considerations" above). It does you no good to start installing six-piece endings if your chess program won't be able to access the tablebases for the other endings that the six-piecers can simplify to. In a nutshell -- if you can't install all of the tablebases and wish to install only a partial set manually, begin by installing the three-piece endings, then work up to the four-piece endings, followed by whichever five-piece endings you want (or have room for). The pamphlet in the Turbo Endgame package provides additional information on the five-piece endings located on Disks #2, #3, and #5. SETTING UP FRITZ9 TO USE THE TABLEBASES This last step will require that you know the location (or locations, if you've manually copied the tablebase files into several drives/folders) of your tablebase files (see "Installation" above). In this final step of the process, we're going to point your Fritz9 program to these locations. 1. Start the Fritz9 program. 2. In Fritz9's "splash screen" select "Play Fritz". 3. When the main chessboard screen appears, go to the Tools menu and select "Options". When a dialogue box appears, click the "Tablebases" tab to get the following dialogue: file:///C|/unzipped/tb_inst/tb_inst.htm (5 of 6) [12/11/2005 11:14:50 PM]
  6. 6. ChessCafe Powerbook/Turbo Endgame Installation You'll notice four entries for "Path". These boxes allow you to select up to four folders on any drive (or even a complete drive itself, if you've chosen to run just DVD #1 direct from the disk). 4. Click the "Browse" button to the right of "Path 1". The "Browse for folder" dialogue will appear; use it to navigate to the main folder (or drive) in which your tablebases are stored. You just click the "plus signs" next to drive or folder names to expand the view until you see your main tablebase location displayed. Highlight it and then click the "OK" button. (In the illustration above, you'll see that my tablebase files are stored in the folder tbases on my C: drive). 5. If you've stored the tablebases in more than one folder, repeat the process as necessary for "Path 2", "Path 3", and "Path 4". Note that a particular location needs to be provided just once; in the illustration above, all of my tablebases are stored in C:tbases, so Paths 2 through 4 are left blank. 6. After you've designated all of your tablebase folder locations (up to a maximum of four), click "OK" to close this dialogue. Although the process of installing tablebases might appear complex, it's really quite simple for most users. If you don't have the required drive space for all five DVDs, simply install DVD #1 and then copy any other desired five-piece endings from DVDs 2, 3, & 5 manually into that same folder into which you installed DVD #1. Then just point Fritz9 to that folder using the last set of instructions I've provided. For additional options, please be sure to consult the pamphlet included with the Turbo Endgame DVD set. © 2005, Steven A. Lopez. All rights reserved.
