Chess480. Fischer Random Chess with orthodox castling rules. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]

Because there is no standard numbering system for Fischer Random Chess (Chess960), it would be hard for me to make a rule to explain which are duplicates due to being mirrors. It's likely that any system for generating all 960 positions would probably start mirroring at 480... so 480 and 481 would likely be mirrored positions.
