Fritz Powerbook 2026 – ChessBase Opening Book

Fritz Powerbook 2026: study chess openings with millions of positions

Fritz Powerbook 2026 is a powerful opening analysis and preparation tool developed by ChessBase. Its huge opening tree contains around 25 million positions generated from approximately 1.7 million high-level tournament games.

For each position you can consult valuable information for building and improving your repertoire, including the moves played, the average rating of the players who used them, success rates and performance statistics.

Discover what is really played in each position

Fritz Powerbook 2026 allows you to quickly investigate which moves have been played from a particular position and which ones have achieved the best results.

• Check the most frequently played moves.
• Compare success percentages.
• Analyse the average Elo of the players.
• Find less common variations.
• Discover new ideas for your repertoire.
• See which lines are used by strong players.

This makes Fritz Powerbook especially useful for tournament players, coaches and chess enthusiasts who want to study opening theory in greater depth.

Three opening books included

The 2026 edition includes three different opening books:

• Fritz Powerbook 2026: the main opening tree based on millions of positions.
• StrongBook 2026: a specialised selection based on games played by very strong players.
• CorrBook 2026: based on correspondence chess games, which are particularly useful for discovering deeply analysed theoretical ideas.

The database is also enhanced with approximately 100,000 of the best games from the Correspondence Database 2026, increasing the theoretical value of the included variations.

StrongBook: games by Grandmasters

Fritz Powerbook 2026 also includes a smaller but highly selective book based on games played by Grandmasters rated 2550 Elo or higher over the last 100 years.

This content is especially useful for studying the lines used by elite players and for seeing which variations have performed best in high-level practice.

In addition to consulting the statistics of each position, you can use Fritz Powerbook to discover new lines and practise them directly against Fritz, making it especially useful for incorporating new variations into your opening repertoire.
