If you’ve had experience using any version of Fritz Powerbook (updated annually for many years now), you already know that it’s a valuable research tool; you can step through a “tree” of opening variations and see a statistical breakdown for all of the millions of positions which are in that tree. You likely also know that using Fritz Powerbook as an alternative opening book for any of the Fritz “family” of chessplaying programs (Fritz, Rybka, etc.) provides the chess engine with a much broader range of openings than the default book which comes with the program.
What some users don’t know is that it’s advantageous to access Powerbook from your hard drive rather than directly from the DVD. You can add manually add opening lines to Powerbook if you choose, and Fritz’ “learning” functions will cause your chess engines to prefer or avoid particular opening variations based on the engines’ past performance in the games they’ve played on your computer.
So how do you get the Powerbook’s files (yes, plural) from the DVD to your computer’s hard drive?
We’ll look at two methods, using ChessBase 11 (the easier of the two) and Fritz12.
The (hopefully obvious) first step is to put the Fritz Powerbook 2011 DVD into your computer’s DVD drive.
Then launch ChessBase 11 (we’ll consider Fritz12 in a moment). In the initial screen (the “database desktop”) click on the plus sign to the left of “Computer” in the lefthand pane in the display:
You’ll see a listing for all of the drives on your computer. One of them will display the entry “Power 2011” followed by the drive letter of your DVD drive. Click the plus sign immediately to the left of it, which will expand the display to show the folders on the Powerbook DVD. Single-click on the folder called “Data”:
You’ll see the upper right-hand (database) display change to show you the contents of the “Data” folder:
We’re interested in copying the Powerbook 2011 to the hard drive. Right-click on the Powerbook 2011 icon and select “Install database” from the popup menu:
The following dialogue will appear:
Click “OK” and ChessBase 11 will copy the Powerbook files to your hard drive. When it’s finished, you can click on the “My Databases” entry in the lefthand pane and see that Powerbook 2011 has been copied to the hard disk and its icon now appears on your database desktop:
Now what do you say we try this in Fritz12? First, of course, put the Powerbook 2011 DVD in your computer’s DVD drive. Then launch Fritz12 and click the “Play Fritz” command to go to the main chessboard screen. Click the button for the Application Menu (in the upper lefthand corner of the screen) to get a dropdown menu. Select “Open” and then “Openings book” from the submenu:
Select your DVD drive from the pulldown menu, then double-click on the “Data” folder to see its contents. You’ll find an entry for “Powerbook 2011”; double-click on it to open it.
After a few moments you’ll see the Notation pane change to show you the book display for Powerbook 2011 (showing a list of opening moves). You’ll then go to the Analysis menu and select the “Copy tree to hard disk” command as shown below:
A new dialogue appears which allows you to select a folder to copy it into. Just go ahead and use the default, unless you have a specific reason for doing otherwise. After you’ve selected a folder (or decided that the default selection is acceptable), click “OK” – Fritz12 will then copy the Powerbook files to the hard drive.
In the next blog post we’ll look at an analytical use for Powerbook 2011.
Have fun! – Steve
