I admit that while I do regularly play chess, I'm not super well versed in either FEN nor Chess960. That said, I've been trying to figure out why you would need a different notation for Chess960 for half an hour now, and I just can't figure it out. All explanations I'm seeing just make some vague mention about ambiguity in the regular notation for Chess960, but I, personally, can't think of a situation in which the regular notation is insufficient.
The KQkq still unambiguously mark which player can castle to which side, and once either a rook or King move for the first time, you just remove the corresponding letter(s). What am I missing?
