I used this project mainly to get a bit deeper into the basic concepts of Python. Right now it is a pretty basic chess engine implementing the majority of the games' rules. It comes with a pygame based GUI and without any computer opponents.

The following projects were a) a massive inspiration for the basic class layout and b) got me a headstart on the use of pygame, so check them out:

b) https://github.com/mikolaj-skrzypczak/chess-engine

To play a game of chess, just run test.py in the root folder.

Open points that I will maybe work on in the future:

• Threefold/fivefold repetition and fifty-move rule/seventy-five-move rule for draws
• Pawn promotion: User interface for choosing the desired piece
• Undo moves
• PGN support
• Online GUI
• Computer/AI opponents
• Some refactoring
