2) 1. exd3ep a8=S 2. d4 Sxb6#
Cook: e.p. not justified as R: 0.e3xd4 possible
VL: Unjustified ep-capture because of –e3xd4. For correction it suffices e.g. to add bSe3.
This is possibly a unique 2-move helpmate with ep-key and 2 solutions of the type 1.2.1.1 (at least so currently in the PDB).
Publi?ation details. H551 in the Helpmate section of the July issue, with no preview. Here is the text of the solution published in the Nov.-77 issue: “…White may have just played P(e3)xd4. Very few solvers have spotted this. Full marks for claim of no solution with correct reasoning but, in fairness, one mark for composer's intention. White cannot have just played K(a5)a6 in reply to Pxb6+ as too many captures by Black are required.” (2023-12-01)
A.Buchanan: Yes Valery you are right this must be cooked. However, I'm not a fan of +bSe3 because it spoils one of the model mates. Separately, I mildly prefer bPf7 to bPe6. (2023-12-03)
VL: I do prefer bPf7, as well. I don't see any way to save at least one of the properties Kindergarten Problem and Model mate (2) after fixing (what for these keywords have been added just now?). Besides, Andrew, please, refine the specification ((full) number and publication month 07-08). (2023-12-03)
A.Buchanan: Ok have added the publication details. The keywords are useful to indicate the aim, even though the problem is cooked. I guess there is a way to keep the model mates but it’s very clunky and probably +bSe3 is better (2023-12-03)

A.Buchanan: Hi Gunter thanks for your scholarship. The specified syntax for PDB is to separate phases by commas. If something only occurs in 1 phase I guess it would be e.g. "L,". It is not a good idea to have multiple occurrences of the same keyword within a problem, because that makes counting & quality-checking more difficult, and is fiendishly difficult to track. Thanks for your understanding. If you have different opinions, please express them here, in German or English. (2022-08-01)

Gunter Jordan: Lieber Yuri, wie mir die Autoren mitteilten, kannten sie die von dir angegebene Stellung (und noch weitere Versionen), doch entschieden sie sich bewusst für ihre Diagrammposition, weil darin Weiß nicht nur drei Anfangszüge hat, wovon sogar zwei lösen, sondern eine größere Auswahl in einer viel freieren Stellung.
