Chess Championship 2024 in Python with Chessnut

Chessnut is a lightweight Python package designed to model a chessboard, handle moves, and track the game’s state. Unlike full-fledged chess engines, Chessnut doesn’t include AI for playing games or a graphical interface (GUI). Instead, it focuses on simplicity and utility, making it an excellent tool for studying chess mechanics or integrating with other chess-related applications.

What Is Chessnut?

Chessnut is a minimalistic package for chess enthusiasts and developers who need a straightforward way to:

• Generate a list of legal moves for a given board position.
