Nr. 4293 (Zipf): „Die Schlüssel mit demselben Turm starten die einheitlichen Lösungen, welche zusammen einen Zyklus bilden: Jeder Mattzug erscheint als Drohung im nächsten Teilproblem wieder“ (K. Keller, Ulm). in der Fachsprache ist dies ein „Pseudo – Le Grand – Zyklus“ (M. Schreckenbach, Dresden) – ein Zyklus von Droh- und Mattzügen auf unterschiedliche schwarze Paraden. Ergänzt wird alles durch zyklische Verführungen mit unterschiedlichen Widerlegungen: a) 1.Td8/Te8? Le1/Ld2! mit der Lösung 1.T8h3! (droht 2.Lc2 (A) matt) Td4 2.Sg3 (B) matt; b) 1.Te8/T8h3?

A complete undoing of the Indian theme with a waiting move, followed by its "redoing" - the whole serving as a tempo manoeuvre. [Problemist]
Henrik Juel: Popeye 4.61 cannot check, because its ReversBauer is just a pawn moving opposite to an ordinary pawn, while the combination does not exist
But this would seem to be a cook:

Alfred Pfeiffer: The Reversible Pawn cannot move to its first rank. Therefore its promotion rank is the 8th rank only. (2019-10-16)

Henrik Juel: Part a) is badly cooked, e.g., 1.La6-b5 Ka3-b3 2.Ka5-a6 Sb2-a4 3.Lc3-a5 Sa4*c5#
Part b) is C+ by Popeye 4.61 (2019-10-17)
Alfred Pfeiffer: I assume, that only the moves have to be within the cells, but for the mates you have to consider the whole board. (On a6 the bK has the flight Ka7) (2019-10-17)
Henrik Juel: If Alfred's assumption is correct, a) is also C+ by Popeye 4.61, as all the 'cooks' end with sK on a6 or b6 (2019-10-17)
A.Buchanan: I.e. it’s a conditional rather than fairy problem (2019-10-18)
Mario Richter: It seems to be usus in the PDB to use the genre "Fairies" in cases where the problem contains some deviation from orthodox rules (eg. fairy conditions, fairy pieces, or, as here, a non-8x8-board [that keyword is still missing here]). My impression is that the keyword "conditional problem" is mainly used for problems that were called "Wettspiele" in the middle-ages (the idea beeing that some kind of games at odds is played, the odds being that the stronger side declares how and where to mate the opponent king before the game starts).
So in contrast to Andrew I wouldn't use this keyword here.
Since "Letter problem" is a well-established term in problem chess, I suggest to replace the keyword "Symbol problem" by "Letter problem".

Regarding the cook, my thoughts were similiar to that of Alfred, but my conclusion was a little bit different: perhaps a little roof on the left segment on a6 and/or b6 is missing? Would adding it suffice? (2019-10-18)
A.Buchanan: Hi Mario: I don’t feel particularly strongly here, but based on what Alfred said, it’s not a non-standard board: the mate in a) must allow for bK exiting the zone. So it’s just the moves are constrained - to my mind this is consistent with the usage of conditional problem in Victorian times. It’s not like maximummer where the nature of mate is affected by the condition, hence fairy. I am in Dubai airport for short stopover but I will doublecheck the positions later (2019-10-18)
A.Buchanan: I'm reminded of monochromatic chess. As an autodidact, Smullyan invented mono independently from everyone else, and in his version, check is not affected by the mono constraint. In a sense, his mono problems are just conditional not fairy: the players are just choosing moves which abide by the condition, under regular rules. But does it make sense to divide up the mono problems into fairy and conditional in this way? What about mono problems (by Smullyan and others) which don't involve the area of disagreement at all? All are mono obviously, but should they all be classed as fairy?
So here a) is like a Smullyan mono problem while b) is like a mono which is neutral on this issue. I think "conditional problem" usage in PDB is broader than just "Wettspiele". We should just classify it as 5x3 but how to denote that it doesn't have to be fairy?
Thanks all (2019-10-19)
