Project Invincible

ject Invincible is an open source chess game that allows you to test your skill against a friend or its own powerful AI. With 3D graphics, the perspective of which you can change using your keyboard, and controls just as easy as playing in real life, the only challenge with this program will be your opponent. You can adjust the program's artificial intelligence to be weaker so that players with little experience can practice without getting too frustrated. It's an excellent way to train and improve your game.
