Chess960 is not starting from the scratch. There has been live before. So for me it is far more relevant that e.g. Shredder could also import X-FEN and Pseudo-FRC games and positions than to care too much for programs not related to Chess960 at all. Such programs will never come in contact to Chess960 games and positions without the errornous intension of a user. >Shredder Fen: >+ By looking at fen, you can tell instantly it is chess 960 >+ Old chess GUI's will reject the fen immediately, and thus will not get >confused. For example, Fritz 8 will (hopefully :) ) reject the Shredder fen >immediately, while it will wrongly think that a X-Fen fen is shuffle chess fen. >- Classical chess position is represented in 2 different ways. >- Incompatible with existing chess960 software What is about existing Online Servers, Game Databases with recorded FRC games? Your sorrows are first targeting chess engines, which are incompatible anyway !? Nevertheless it would be good to see thoughts of others. Because it could make sense to find a better compromise than to have a solution established fast but with additional problems created. Reinhard.
