But 'x' would not be acceptable, as it would make the SAN notation ambiguous: the is also used as a capture indicator.
This is an excellent point. ChessV doesn't use SAN at all and I'm not really familiar with it so this didn't occur to me. Probably best that I change the extra files to 'y' and 'z'.
