History
Krzysztof kuhy Rudnicki 275399a72c Fix test discovery and coverage for python_pkg modules 
- Update pytest testpaths: PYTHON -> python_pkg (PYTHON was empty)
- Add missing __init__.py to: stockfish_analysis, screen_locker, extract_links
- Now coverage correctly reports 0% for untested modules:
  - screen_locker/screen_lock.py (279 stmts, 0% coverage)
  - stockfish_analysis/analyze_chess_game.py (327 stmts, 0% coverage)

Chess move analysis with Stockfish

This utility parses a PGN (or a log that contains a PGN section) and evaluates each move with a local Stockfish engine, printing a per-move quality rating.

Install

Install python dependencies:

pip install -r PYTHON/stockfish_analysis/requirements.txt

Ensure Stockfish is installed and available in your PATH (or provide the path via --engine). On Linux, you can typically install with your package manager or download a binary.

Run

From the repo root:

python3 PYTHON/analyze_chess_game.py lichess_bot_game_8GSdY3Ci.log

Options:

  • --engine /path/to/stockfish to specify a custom engine path
  • --time 0.2 seconds per evaluation (default)
  • --depth 12 fixed depth instead of time

The script prints a table with, for each ply:

  • side to move, SAN move, eval before/after from mover's POV, delta, classification, and Stockfish best move suggestion.
