[Retros] The paradigmic divide on (retro) Rules and Conventions

[Guus Rol]

Hi Andrew,

Set-approaches simplify "retro-analytic reasoning". To find out if move
X is legal or not legal in some diagram or during a solution, all you do is
look in the DGC-set for any game where move X is played at that point. The
convention makes further reductions and the FIDE law rounds it off. That is
of course the theory. In practice, solvers will still have to do their
retro-analytic labour to get to the same outcome.

In the 19th century, applications in physics did not require Einsteins
"relativity theory" but after Einstein developed it a lot of physics did.
As soon as workable laws and principles have been established, the
technicians will start building machines and other stuff. It is true that
most of the retro domain is currently filled by purely retro-analytic
problems but I hope to increase the retro-active share by delivering sound
and expandable concepts for it. Note, that I spent the past years by
developing and publishing (some, not many) very good examples of my theory
in PB as a preamble to its presentation. I have good grounds for believing
that retro-activity is a fruitful subject for composition also in the fairy
domain.

Regarding the mate/e.p. issue, lets skip the diagram since it is trivial to
explain:."White is mated in the diagram unless he can play e.p. which is a
right that cannot be proved". What I recall - I do have problems mining my
data resources for reference - is that you consider this situation
"indeterminate" under the current laws and conventions. If not, please give
me you actual viewpoint and explanation. If I am wrong, I of course retract
all the comparative statements I made about it.
In general I will validate my theories on a conceptual level and do not
mind breaking any and all chess laws in that process including King
captures. I will argue that Bishops move over the full diagonals on a 9 by
9 chess board even when only a picture with 8 diagonal crosses is shown in
a FIDE law book. When laws are applied to areas  they were not designed
for, it is wiser to follow their concepts than to implement them literally.

Best wishes, Guus Rol.
