Step-by-Step Guide to Add a New Opening Book in ChessBase

1. Get the Opening Book File

ChessBase opening books come in different formats, but the most common format is the .ctg extension. These opening books contain a collection of opening lines with moves, statistics, and evaluations.

• Where to Find Opening Books:
  • You can download opening books from various websites, such as ChessBase, Lichess, or community-driven repositories.
  • You can also create your own opening book from games or databases (see Step 6 for more on this).

2. Save the Opening Book in the Correct Folder

Once you have the .ctg file (or any associated book files), you need to save it in the correct folder.

• By default, ChessBase stores opening books in a specific directory. You can choose any location, but it's often easiest to place it in the default book directory for easier access.

  Default Directory Path:

  Documents\ChessBase\Books
  

  Place your .ctg file in this folder, or you can create a new folder for organization if desired.

3. Open ChessBase

Once your file is stored in the correct location, open ChessBase on your computer.

4. Load the Opening Book in ChessBase

Now, it’s time to load the book within the ChessBase interface.

1. Click on the 'Open' Button (or go to File > Open in the menu bar).
2. Select 'Openings Book'.
   • In the dialog box that appears, navigate to the folder where you saved the .ctg file.
   • Select the opening book file and click Open.

5. Activate the Opening Book

Once you have loaded the opening book, you can activate it to use in your games or preparation.

1. Open the Board Window where you play or analyze games.
2. Go to the 'Book' Tab at the bottom right of the board window.
3. You should now see the loaded opening book with moves and evaluations based on the opening positions in the file.

6. Create Your Own Opening Book (Optional)

If you want to create your own custom opening book from a collection of games, follow these steps:

1. Create a New Opening Book:
   • Open ChessBase, and from the File menu, select New > Opening Book.
   • Choose where to save your new .ctg file and give it a name.
2. Add Games to Your Opening Book:
   • Open a database with the games you'd like to include.
   • Select the games you want to use (you can use Ctrl+click to select multiple games).
   • Right-click and choose Add to Book.
3. Configure the Book Settings:
   • Once the book is created, you can configure its options, including weighting certain lines, marking favorite lines, and adjusting frequency.

Additional Tips

• Multiple Files: Opening books may come with .ctg, .cto, and .ctb files. Make sure all related files are in the same folder for the book to work properly.

• Improving Opening Knowledge: Once the book is loaded, you can right-click on moves to add personal comments, evaluations, or additional variations.

• Updating a Book: If you want to update an existing book with new games, simply add those games to the database, and then import them into the opening book using the Add to Book feature.

• Book Settings: You can adjust the behavior of the book (how often a move is selected, how much priority is given to certain lines) by right-clicking within the book pane and selecting Properties.
