One dimensional Chess Variants. A page detailing some one dimensional chess variants.

`That is an idea. Make a variant mapping 2D to 1D but remove and ignore the separators. And then change other rules if needed, including board setup, if that would improve the game.`

```'knight must
jump over at least one separator when moving' - it's not only separator limitation of FIDE chess on 1D board. Knight must jump over exactly 1 sparator to leap 10 squares and over exactly 2 to leap 17 squares. Bishop is (9) and (7) rider, but with each of it's leaps it must jump over exactly 1 separator. Rook can't cross separators when moves as rook, but it can move freely as (8) rider.
And here are rules for new game: what if separators are ignored?! :D```

Now that I've had more time, I've found it. It's EEEEEEEEEEEEEEEEEEEEEEEX! Chess.

This was done once, although offhand I can remember neither the name nor the inventor.

`Of course, another one dimensional chess is simply the mapping from the 2D board of FIDE chess to a 1D board. You need to add separators and a rule that a knight must jump over at least one separator when moving.`
