However: that´s not a ´presupposition for´ but simply a ´conclusion from´ his next statements. 2)"The extension will cause errors": Absolutely correct! If any of the existing chess-GUIs (not being prepared for FRC/Chess960) will receive a "KQkq" castling from a FEN, it will assume kings on e-file and rooks on a/h-file. But in X-FEN even with this "KQkq" the kings and rook could be located almost ´anywhere´ - so what do you think the GUI will do, when getting any castling move (O-O, O-O-O) during the game replay, without even finding both pieces on their original places?? In the best case th GUI will simply produce nonsense, in the worst case it may even crash - both of course are "errors", as mentioned in the above statement! 3)"Similiar looking FEN positions will have a different meaning": Of course this is also only related to castling rights. In X-FEN really _every_ of the 960 starting positions has the _same_ castling tag "KQkq", although they have indeed a _completely_different_ meaning (i.e. other positions of king and rooks, and therefore also an other move sequence). 4)"Chess960 finally is not compatible to traditional Chess": Again absolutely correct! Chess960 is a superset of classical chess, and the big majority (942/960) of the starting positions are definitely _contradicting_ the classical chess rules (with regard to castling)! Would you call this ´compatible´?? (If ´yes´, you´ll certainly be the only one) Well, that´s now really my last statement about this annoying X-FEN disussion, but of course feel free to continue your boring campaign to persuade (or even try to force) people to use this crazy X-FEN format by spamming almost every chess forum in this wide world with your X-FEN ´informations´(?). But wait another half year - then you´ll get answers like this: "What the hell is X-FEN?" ;-) (oder auf gut Deutsch: "Welche Hahn wird dann noch nach X-FEN krähen?") Franz.
