What is XBoard/WinBoard?
XBoard and WinBoard are graphical user interfaces for chess. XBoard runs on Unix systems, WinBoard on 32-bit Windows systems. Both programs display a chessboard on the screen, accept moves made with the mouse, and load and save games in Portable Game Notation (PGN). They serve as a front-end for many different chess services. The WinBoard distribution includes a port of GNU Chess. XBoard and WinBoard are free software.
