Winboard serves as a front-end for many different chess engines.

• WinBoard displays the chess board on the screen, accepts moves made with the mouse, and loads and saves game files in standard chess notation.
• You can play a game against an engine, set up arbitrary positions, force variations, or watch a game between two engines.
• Winboard has an extensive help file.
