[Retros] « Straight Line » Chess

[Éric Angelini]

Hello Retro-fans,
I’ve posted (in French) a new (?) variant here
(on my personal blog — with some diagrams),
a month ago:

https://cinquantesignes.blogspot.com/2021/03/echecs-ld-ligne-droite.html

In short:
« SL Chess » (Straight Line)
A chess unit U leaving its starting square S
in order to occupy the square E determines
automatically a straight line SE which this
piece must not leave in the future.

The White’s pawn that plays e2-e4, for
instance, will never capture in the future,
as it is assigned to the column « e »; it will
only be captured, stay on e4 or advance —
and promote perhaps on e8 (the promoted
piece will determine a new SL after its first
move — if it moves).

If Black, after White’s move e2-e4, replies
with the curious move Kb8-a6, this Knight
will oscillate forever between the squares
b8 and a6.

Diagrams #2 to #8 on my page successively
illustrate:
a Black King in check,
a checkmated Black King,
a capture,
a castling by White,
a forbidden prise en passant by Black,
a legal position (two Kings on adjacent squares)
an illegal position (two Kings on adjacent squares).

I hope this is not old hat on this forum — and
that this variant will inspire a few members,
especially in the Retro genre.
