GUI created for the project chess_pos_db. It requires chess_pos_db.exe to be present in the same directory. A chess_pos_db.exe process is spawned by the gui (previously ensuring that it's not already present by killing all of its instances) and a TCP connection in made through which the requests are made.

• Chess board display

  • draggable pieces
  • move history
  • easy way to set a position from FEN
  • easy way to set whole move history from PGN
  • board flipping, resetting
  • copy FEN
  • board and piece themes

• Excel-like data display

  • (Automatic) querying of position data from a loaded database

  • empirical WDL, perf%, draw%, human%

  • average elo difference between players for each position (if available) and adjusted performance based on expected performance

  • Filtering of queried data:

    • by game level (human, engine, server) (based on partitioned PGNs during the database creation)
    • continuations and/or transpositions

  • Evaluation data (cp and perf%) provided by (https://chessdb.cn/queryc_en/), building up on a massive effort by Bojun Guo (noobpwnftw)

  • Display for the data about the first game with the given position.

  • Statistically sound move quality calculation

    • based on empirical performance, confidence (based on frequency), expected performance based on elo differences, and engine evaluation from chessdb.cn.
    • configurable weights
    • optional normalization

• A tool for dumping all FENs for all positions with at least a given number of instances into an EPD file.

• Configurable local engine analysis.

• User friendly GUIs for creation and management of position databases (with chess_pos_db backend).

• Chess DOT Net
• chess_pos_db binaries

Put the compiled artifacts and the assets folder (or unzip the released binaries) into a directory with chess_pos_db.exe.
