How to Expand an Opening Book in Fritz Using PGN Files

 

A practical guide to growing your opening database with real games

---

Introduction

An opening book is one of the most powerful tools inside Fritz. It allows the engine to play strong, theory-based moves instantly in the opening phase, instead of calculating everything from scratch.

If you’ve downloaded PGN game collections from websites (which is exactly the right place to start), you can use them to expand and strengthen your Fritz opening book, making it richer, deeper, and more up to date with modern theory.

This guide walks you through the full process—step by step.

---

Step 1: Get High-Quality PGN Files

Yes, you start exactly where you suspected: PGN databases.

Good sources include:

• Online chess game repositories

• Tournament databases

• Engine vs engine tournaments

• Your own played or analyzed games

💡 Tip:
The quality of the opening book depends on the quality of the games. Prefer:

• Grandmaster games

• Engine tournament games

• Recent games (last 5–10 years)

---

Step 2: Import the PGN into Fritz / ChessBase

Fritz works hand in hand with ChessBase.

1. Open Fritz

2. Go to File → Open → Database

3. Open (or create) a database where you’ll store the PGN games

4. Import the PGN:

   • File → Import → PGN

   • Select your PGN file

   • Let Fritz convert it into a ChessBase database

Once imported, you should see all games listed and playable.

---

Step 3: Create or Select an Opening Book

Now comes the key part.

1. Go to Tools → Opening Book → Create New Book
   (or load an existing .ctg book)

2. Give the book a name (example: My_Expanded_Openings.ctg)

3. Choose a location (default ChessBase Books folder is recommended)

This .ctg file is your actual opening book.

---

Step 4: Add Games to the Opening Book

This is where your PGN games become opening knowledge.

1. Open the database containing your imported games

2. Select the games you want to include:

   • Ctrl+A to select all

   • Or manually select only high-quality games

3. Go to:
   Tools → Opening Book → Add Games to Book

4. Choose your .ctg opening book

5. Let Fritz process the games

Depending on the size of the PGN, this may take a few seconds or several minutes.

---

Step 5: Adjust Book Settings (Very Important)

After adding games, you should fine-tune how Fritz uses them.

Open Opening Book Settings and adjust:

• Minimum Games (e.g. 2–5)

• Weight by Elo (recommended ON)

• Ignore short draws (strongly recommended)

• Prefer main lines (optional, style-dependent)

💡 This step prevents weak or dubious lines from polluting your book.

---

Step 6: Test the Expanded Opening Book

Now test your work.

• Start a new game with Fritz

• Make sure your custom opening book is selected

• Observe:

  • Does Fritz play deeper theory?

  • Does it stay “in book” longer?

  • Are opening choices more varied?

You can also:

• Enter Analysis Mode

• Navigate opening positions manually

• See statistics: win rates, draws, popularity

---

Step 7: Keep Improving the Book Over Time

An opening book is never finished.

Best practices:

• Periodically add newer games

• Remove outdated or refuted lines

• Maintain separate books for:

  • Classical chess

  • Blitz / Rapid

  • Chess960

Many advanced users keep multiple opening books depending on purpose.

---

Common Mistakes to Avoid

🚫 Adding low-quality blitz games
🚫 Mixing engine test games with human games randomly
🚫 Forgetting to weight games by Elo
🚫 Overloading the book with too many weak sidelines

A smaller, cleaner book often plays stronger than a massive messy one.

---

Final Thoughts

Expanding an opening book in Fritz is not just technical—it’s strategic.

You are shaping:

• What Fritz plays automatically

• How it understands modern theory

• Which positions it reaches most often

With well-chosen PGN files, your opening book becomes a silent coach, guiding every game before calculation even begins.

How to Add a New Opening Line to the Opening Tree in Fritz

 

When the opening tree stops and your moves are not there yet

---

The Core Problem (What’s Really Happening)

In Fritz, the Opening Tree is not magical.
It only shows moves that already exist in its underlying database or opening book.

So when:

• You reach move X

• And the Opening Tree suddenly stops

• And your desired continuation does not appear

👉 It means that line does not exist yet in the tree.

The good news?
You can manually inject that line and force Fritz / ChessBase to learn it.

---

Important Distinction (Tree vs Book)

Before we proceed, clarity matters:

• Opening Tree → statistical view (games-based)

• Opening Book (.ctg) → move-selection engine logic

To make a move appear in the Opening Tree, it must exist in at least one stored game.

---

Method 1: The Correct & Clean Way (Recommended)

Add the Missing Line by Creating a Game Manually

This is the proper way ChessBase was designed to work.

---

Step 1: Create a New Game with the Missing Line

1. Open Fritz

2. Click New Game

3. Play the opening manually:

   • Enter all moves up to and beyond where the tree stops

   • Include the new move you want to appear

💡 You only need one game for the line to exist.

---

Step 2: Save the Game into a Database

1. When done, click Save Game

2. Save it into:

   • Your main opening database, or

   • A dedicated “Opening Experiments” database

Name it clearly (example):

Experimental Line – Najdorf h4 novelty

---

Step 3: Rebuild the Opening Tree

1. Open the database containing the new game

2. Go to Tools → Opening Tree

3. Let Fritz recalculate the tree

✅ The new move now appears as a legal branch.

Even with 1 game, the tree will show:

• Move

• Game count = 1

• Statistics (basic)

---

Method 2: Use a Mini PGN Injection (Fast & Efficient)

If you prefer speed:

1. Create a PGN file with:

   • Exactly one game

   • Only the opening line (can end early)

2. Import that PGN into your database

3. Refresh the Opening Tree

This is how many advanced users force theoretical novelties into the tree.

---

Method 3: Strengthening the Line (So It Doesn’t Look Weak)

A single game works—but looks thin.

To make the line look serious:

• Duplicate the game

• Slightly alter move orders (transpositions)

• Save multiple versions

This increases:

• Game count

• Statistical weight

• Tree credibility

---

Method 4: Add the Line to the Opening Book (Optional but Powerful)

If you want Fritz to play the line automatically:

1. Load your .ctg book

2. Use Add Games to Book

3. Select your injected games

4. Rebuild the book

Now:

• Tree shows the line

• Engine actively plays it

---

Why Fritz Doesn’t Allow “Manual Tree Editing”

You might ask:

“Why can’t I just right-click and add a move?”

Because:

• The Opening Tree is derived, not editable

• It reflects games, not opinions

ChessBase enforces this to prevent:

• Fake statistics

• Artificial theory pollution

Ironically, this makes your method more powerful, because:

One game = one new universe

---

Common Mistakes to Avoid

🚫 Waiting for online databases to update
🚫 Thinking the engine will invent tree moves
🚫 Adding the move only in analysis (analysis ≠ tree)
🚫 Forgetting to save the game

---

Mental Model (Think Like This)

• Tree = memory

• Game = neuron

• Saving a game = learning

No game → no memory → no branch.

---

Final Thoughts

If an opening line does not exist, Fritz is not blocking you.
It’s asking you to create theory.

Every novelty—human or engine—starts with one saved game.

That’s how:

• New openings are born

• Private repertoires are built

• Engines are guided into unexplored territory

How a Million Miles of Undersea Cables Power the Internet — and Now AI

 

Beneath the calm surface of the oceans lies one of the most critical—and least visible—infrastructures of modern civilization. Stretching across the seabed is a vast web of over one million miles of undersea fiber-optic cables, quietly carrying the lifeblood of the digital world. These subsea cables transmit more than 95% of all international data, making them the true backbone of the internet—and increasingly, of artificial intelligence.

The Hidden Highways of Global Data

While satellites often get the spotlight, they handle only a small fraction of global data traffic. Subsea fiber-optic cables, by contrast, move information at near light speed with far greater capacity and reliability.

Through these cables flow:

• Emails and instant messages

• Video calls and streaming services

• International banking and financial transactions

• Military, diplomatic, and government communications

Every cloud service, search query, and global collaboration depends on these underwater connections. Without them, the modern internet would simply collapse.

Why AI Is Changing Everything

Artificial intelligence has dramatically increased the demand for bandwidth, speed, and low latency. Training large AI models and running real-time AI services require enormous data transfers between global data centers.

This is why major tech companies—such as Google, Amazon, Meta, and Microsoft—are investing billions of dollars into building and owning subsea cable networks.

These cables are no longer just about connecting people; they are about connecting machines to machines, enabling:

• Faster AI training across continents

• Real-time AI inference and cloud computing

• Synchronization between massive data centers

• Scalable global AI services

In short, AI runs on cables.

From Public Infrastructure to Corporate Control

Historically, undersea cables were built by telecom consortia. Today, Big Tech is becoming the dominant force behind new cable projects. By controlling the physical infrastructure, companies gain:

• Lower operational costs

• Greater security and redundancy

• Faster global data access

• Strategic independence from traditional carriers

This shift raises important questions about digital sovereignty, data control, and who truly governs the global flow of information.

Fragile Yet Essential

Despite their importance, undersea cables are surprisingly vulnerable. They can be damaged by:

• Earthquakes and underwater landslides

• Ship anchors and fishing equipment

• Deliberate sabotage or geopolitical conflict

A single cable failure can disrupt internet access for entire countries. As AI and cloud dependency grow, protecting this infrastructure becomes a matter of economic and national security.

The Physical Backbone of the Digital Age

The internet is often described as “wireless” or “cloud-based,” but the reality is far more physical. AI may feel abstract and invisible, yet it depends entirely on glass fibers thinner than a human hair, laid across the ocean floor.

As artificial intelligence reshapes economies, warfare, healthcare, and culture, one truth becomes clear:

The future of AI doesn’t just live in code—it runs through the oceans.

---

Final Thought

Undersea cables are the silent giants of the digital world. They powered the first wave of globalization through the internet—and now they are fueling the next era, where AI becomes the dominant force shaping humanity. The question is no longer whether these cables matter, but who controls them—and to what end.

World’s Best Chess Stars Land in Doha for a Rapid and Blitz Showdown

 

Doha is officially in full chess mode. The world’s elite have gathered in the Qatari capital for the FIDE World Rapid and Blitz Chess Championships 2025, running through December 30 at the Qatar University Sports and Events Complex.

As the chess calendar races toward its finale, Doha has become the global epicenter for speed chess—where instinct, precision, and nerves of steel decide champions in seconds.

---

Carlsen Leads a Stacked Lineup

At the center of attention stands Magnus Carlsen, the world number one and top seed in both the Open Rapid and Open Blitz events.

With five World Rapid titles and eight World Blitz crowns, the Norwegian legend once again arrives as the man everyone wants to dethrone. In speed chess, Carlsen’s ability to thrive under pressure makes him uniquely dangerous.

Sharing the spotlight are:

• Gukesh Dommaraju, the reigning world champion

• Volodar Murzin, current World Rapid champion

• Ian Nepomniachtchi, world number two

Fan favorites like Fabiano Caruana, Anish Giri, Wesley So, Levon Aronian, and Alexander Grischuk round out a field that reads like a hall of fame.

---

Young Stars Ready to Shake Things Up

This year’s championship isn’t just about established legends. A new generation is arriving with speed, fearlessness, and nothing to lose.

Rising stars include:

• Arjun Erigaisi

• R Praggnanandhaa

• Nodirbek Abdusattorov

• Vincent Keymer

• Yagiz Kaan Erdogmus

• Ediz Gurel

In rapid and blitz formats, youth can be a weapon—and every round brings the possibility of a major upset.

---

Women’s Championship Delivers Elite Competition

The Women’s Championship features 130 players, led by world number one and reigning women’s blitz champion Ju Wenjun.

Challenging her are some of the strongest names in women’s chess:

• Tan Zhongyi

• Alexandra Goryachkina

• Koneru Humpy

• Kateryna Lagno

• Bibisara Assaubayeva

• Anna Muzychuk and Maria Muzychuk

With depth, experience, and explosive talent, the women’s event promises drama until the final move.

---

Big Stakes, Bigger Prizes

Doha is making history as the only city to host the World Rapid and Blitz Championships twice, having previously done so in 2016.

The financial stakes are equally historic:

• Over €1 million total prize fund

• €700,000 for Open events

• €300,000 for Women’s competitions

Champions will earn:

• €70,000 each for Open Rapid and Open Blitz

• €40,000 each for Women’s Rapid and Blitz

In speed chess, every second can now be worth thousands.

---

How the Tournament Will Play Out

Rapid Format

• Open: 13 rounds

• Women: 11 rounds

• Time control: 15 minutes + 10 seconds per move

Blitz Format

• Swiss phase: 19 rounds (Open), 15 rounds (Women)

• Top four advance to knockout semi-finals

• Pure adrenaline from start to finish

---

Final Thought

With legends defending their legacy, young stars hunting glory, and life-changing prize money on the line, Doha is delivering a fitting climax to the chess year.

Speed chess strips the game to its essence—intuition, courage, and control under chaos. And in Doha, the world’s best are proving that even at lightning pace, chess remains a battle of minds.
