♟️ Comment utiliser notre moteur ♟️

Si vous voulez lancer le moteur sans interface, il suffit de lancer "un_contre_un.py".

Pour lancer le moteur avec une interface, ce sera le programme "uci.py" qui va lancer le moteur, il suffit de mettre dans "IDU3.bat" les lignes suivantes:

• @echo off
• python uci.py %*
• pause

⚠ ATTENTION ⚠

Il faut au préalable avoir installé la bibliothèque chess.py.

PolyChess

PolyChess (named polychess as Git repository) is a Chess engine written in Python and used as practicals for a course on project management at the engineering school Polytech Annecy-Chambéry.

The aim of this repository is not to provide any complete Chess engine since students have to do it based on python-chess. As a consequence, persons interested in this project should check the different forks.

The required features for PolyChess are:

• PolyChess is able to play against a user, or to play against itself (through UCI and Winboard on Windows, or Arena on Mac)
• The games played are stored in PGN format in a directory games, the PGN headers have to be filled
• PolyChess can render the board either in text (on the console) or in SVG (thanks to python-chess, in Jupyter Notebooks)
• PolyChess has an opening book (first as a Polyglot book, then using your own format)
• PolyChess is able to play on Lichess (and eventually FICS)
• PolyChess is modular, it is then easy to isolate a feature and to modify it
• PolyChess has an AI (easy to modify) that could play for the engine
• It is possible to enter a FEN position and obtain an evaluation from PolyChess

Milestones for the project

Milestone 1:

PolyChess is able to play against user or another engine through UCI, has an opening book and an AI

Milestone 2:

PolyChess plays on Lichess (and FICS)

Milestone 3:

Board representation and legal moves are no longer provided by python-chess but are students' responsibilities
