Net Versus was a series of games in Japan that basically allowed you to play various table type games over the net.  This particular one allows you to play chess.  The interface on these games is a right pain in the arse at first resulting in some confusion on how to actually get in to the game part.  Thankfully these games are playable off line as well as on line meaning that you can always have a two player game even if you have no internet connection.

Net Versus is the only chess game for the Dreamcast so there's not exactly much competition for it to go up against.
