What is XChess?
XChess is an older chessboard program that is no longer supported. XChess was written for X version 10, and you may or may not be able to build and run it on an X11 system. XChess has only one significant feature that is not present in XBoard: Two humans can play chess using XChess on different machines, without using the Internet Chess Server as an intermediary. This feature is of interest only if you don’t have network connectivity to the Internet Chess Server. Note: There actually have been several different programs called “XChess” in circulation at various times. The above describes one that was associated with GNU Chess.
