Hi Reinhard, As I can see it, both X-Fen and Shredder Fen have their advantages. X-Fen: + Compatible with existing chess960 software + Represents classical chess fen in the correct way - By looking at the fen, it is difficult to tell whether it is for Chess960 or Shuffle chess - Old Gui's will take chess 960 fen as shuffle chess, some might even become confused. 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 Pallav
