Organizing Engine Tournaments in ChessBase/Fritz

 Chess engines have unique playing styles, which can lead to surprising results when they face each other. For example, Engine A might easily beat Engine B but struggle against Engine C, even if Engine C loses to Engine B. To truly measure a chess engine's strength, it's essential for each engine to play against a diverse range of opponents. The best way to achieve this is through Round-Robin tournaments.

Setting Up an Engine Tournament

ChessBase and Fritz offer easy, automated setup for engine tournaments. Here’s how you can configure it:

1. Engine – Tournament Menu
   Access the Engine – Tournament menu to invite engines to compete. You’ll specify key settings here, including opening books and time control. You can even pause the tournament if you need to use your computer and resume it later.

2. Choose a Tournament Name
   Name your tournament (with a .cbtourn extension) to create a record of participating engines, settings, and results.

Tournament Configuration Options

• Engines and Opening Books
  Choose from installed engines and assign each an opening book. You can set specific options for each engine, like book depth, hash table size, and move preferences.

  • Unify Book: All engines use the same opening book.
  • Unify Hash: All engines share the same hash table size, creating a level playing field.

• Time Controls
  Select either:

  • Blitz for fast-paced games, or
  • Long Game for classical, tournament-style time controls.
  • Permanent Brain: Allows engines to think on the opponent's turn, boosting their strength but using more processor time.

• Tournament Types

  • Round-Robin: Each engine plays multiple games against every other engine based on the number of cycles specified.
  • Run the Gauntlet: The first engine faces every other engine a set number of times, ideal for testing individual engines.
  • Knockout: Engines compete in pairs, with the winners advancing to the next round.
  • Swiss System: Engines with similar scores face each other each round, providing competitive pairings and requiring fewer rounds.

• Database and Output Options

  • Opening Database: Choose a database to control the selection of openings. Alternate colors can be set to ensure color variation in every game.
  • Game Storage: All tournament games are automatically saved in the tournament database located under c:\My Documents\ChessBase\CompBase\EngTourn unless specified otherwise.

With these settings, you can create a tailored engine tournament, allowing each chess engine to showcase its strengths and weaknesses. Whether you prefer a Round-Robin for complete analysis or a Swiss format for quicker results, ChessBase/Fritz provides a versatile platform for exploring engine capabilities. Enjoy watching your engines battle it out on the board!
