Maybe the protocol >that is used there to support this variation is not so bad to adopt also in >winboard. Arena supports FRC as good as possible. But there are different cominations to handle: FRC-aware/conventional with UCI/Winboard playing normal/fischerandom. Because of differences between UCI and Winboard in encoding castlings, (Winboard overmore encodes differently depending on FRC or not) the GUI has to perform very unecessary translations between move encodings. It would be completly sufficient to support the compatible FEN extension FRC-FEN (see: [http://www.rescon.de/Compu/fullchess5_e.html]) and forget then unnecessary "variant" specifications like NORMAL/NOCASTLE/FISCHERANDOM, and encode castlings always using O-O or O-O-O. Regards, Reinhard.
