This is a Chess game with a custom Negamax AI. It is coded using the MonoGame framework and it targets Windows.
There is nothing fancy about the UI. This is meant to be an excercise in creating a strong AI that can play a game as complicated as chess. That's all! There are way better implementations out there (like Stockfish), but I'm doing this as a hobby because I'm interested in AI.
