TC Chess is a classic chess game with difficulty settings. For the hardcore chess enthusiast, there is a difficult setting which uses a very advanced virtual intelligence engine. In difficult mode, you would swear you were playing a thoughtful human opponent, and the play is much slower, but very challenging. In easy mode, the play is much faster, as the VI engine is relaxed, but it is still challenging for the casual player. Do not overwrite any newer files that already exist on your system during setup if prompted. Also ignore the "sysinfo.ocx" file in use message during setup if encountered, the game will run fine. Obviously if the file is in use, you already have it.
