Henrik Juel: What is the joke, James?
Natch 3.1 found no solution (2020-08-26)
James Malcom: The solution has now been added in, Henrik.

This PG has two purposes.
1) It is another exploration of what themes be realized with the dummy pawn involves.
2) It is also to push the boundaries of how long a dummy pawn PG can be made. (2020-08-27)
Henrik Juel: Thanks, James
Apparently you also extended the proof game; the one I tested was in 10.5
The solution shows the Schnoebelen theme, by the way (2020-08-27)
Henrik Juel: You forgot to remove wPf2 from the diagram position (2020-08-27)
James Malcom: Removed, and yes I did manage to find a way to extend it by a ply, in theme for its purpose. The version is also C+. (2020-08-27)
A.Buchanan: I think sLb1 is kind of anti-Belfort Any way to replace it with a Phoenix/Prenix knight? (2020-08-27)
Henrik Juel: Strictly speaking, this is not Belfort, which requires two units to stand away
As Andrew suggests, if sLb1 were a black knight, we would have Belfort (2020-08-27)
A.Buchanan: It's limiting to just talk about Belfort Theme - one historical tourney which had a fiddly constraint about the number of pieces exhibiting the property. Want really to talk more generally about Belfort *Effect*, which is a property of a single unit (2022-01-26)

James Malcom: The point of this PG was to make a true Belfort, after the lone bishop in P1379376 was pointed out to not be a true Belfort. (2020-10-28)
A.Buchanan: Belfort is not in the Encyclopedia! (2020-10-30)
Henrik Juel: For some reason, the diagram is completely wrong
The animation works fine, though (2020-10-28, hidden)
James Malcom: Thanks for fixing the diagram, Mario. (2020-10-28, hidden)
A.Buchanan: A lone bishop can be a Belfort piece. A random tourney at Belfort a long time ago sloppily said that one needed two Belfort units with no other constraints (e.g. avoiding pieces on the wrong piece squares, which is utterly essential for the theme). We can tidy up the definition properly and I think that one Belfort piece could be enough. Why stick with the chaos of the past? (2020-10-29, hidden)
A.Buchanan: I think the notion of a Belfort piece is the foundation idea. Then the question of whether a composition is a Belfort is derived from that, and should include other criteria as well. The original tourney succeeded in launching this idea, but we are surely allowed to clean up the position definition. I will check in the Encyclopedia (2020-10-30, hidden) more ...
