Part 7: Practical Tips for Humans Using the Book

Even if you are a human (not an engine), you can learn from this book. Here is how:

  1. Study in Analysis Mode: Load the CTG in Fritz, play a move as White, and see the colored lines (Green = good, Red = bad). Study why the book rejects certain natural moves.
  2. Use the “Handicap” Feature: Lower your engine strength and play against the Hiarcs 15q book. You will quickly learn which openings you are weak in.
  3. Export to PGN: You can export the entire CTG tree to a PGN file. Open that in ChessBase or SCID and memorize the top 3 moves for your favorite repertoire.

Using this violates copyright law. | | Malware | Popular repacks (from Pirate Bay, RuTracker, etc.) often contain trojans, keyloggers, or cryptominers. The .exe repack installer may be malicious. | | Book Integrity | The repacker may have modified the book’s evaluation scores or inserted dubious lines. You cannot trust that it matches genuine Hiarcs quality. | | No Updates | Official Hiarcs book updates require a license. A repack will never receive legitimate patches or support. |

Part 6: How to Combine Hiarcs 15Q with a Modern Engine

The magic happens when you pair the Hiarcs 15Q CTG book with a modern engine. Here is the ultimate workflow:

  1. Book Phase (Moves 1–15): Let the CTG book control the engine. Set your GUI to "Auto-Play book moves."
  2. Transition Phase (Moves 16–25): Use a hybrid. Set your engine (Stockfish 16 or Dragon 3.2) to a low depth (e.g., Depth 20) just to avoid book traps.
  3. Pure Engine Phase (Move 26+): Unleash full power. Let the engine calculate at Depth 35+.

Because the Hiarcs 15Q repack includes the CTG format, you can program this sequence automatically in Fritz via "Time Control" settings.
