RexChess is a classic chess program released for DOS in 1989, developed by computer chess pioneers Larry Kaufman and Don Dailey. Recognized for its strong playing engine during the late 80s, it provides a challenging match for chess enthusiasts alongside a straightforward, no-nonsense interface.
How to play
Matches follow standard chess rules. As a DOS application, you control the game using your keyboard to navigate menus and input your moves. If you want to play in full-screen mode, press Right Alt + Enter.
Tips
- Take advantage of the engine’s built-in difficulty settings if the default level is too challenging; reducing the computer’s thinking time will make it easier to beat.
- Since matches can run long, use the emulator’s save state feature to pause and resume your game at any time.
