The Chess Computer for nerds, by nerds.
Picture by Picture#
ACID Chess is a chess computer written in Python, which can be used with any? board. By filming the board, the contour of the board is recognized, and the positions of the individual pieces can be determined.
Two Neural Networks were trained for the board and squares recognition.

added support to play on Lichess
You can play against an engine, Stockfish or Maia are available, or play a game against another human. In both variants, a PGN is generated, which you can load later in the analysis board at Lichess, or so, for analysis.

I want to play against ACID!#
We have tested ACID Chess with four different boards and were able to complete games without significant flaws. There will be problems on unknown boards, but every tester makes ACID Chess better!
Regardless of the chosen installation method: ACID Chess saves images of data that cannot be classified sufficiently.
