Author's note: I felt an obligation to the honour of my home town to fix P1359502. I also wanted to make the problem a bit easier. Any moves beyond three seemed non-thematic, as well as rendering the problem harder to solve. Removing wK gives a hint of the funny business afoot. Also Popeye does not handle Rex Multiplex currently. Use of "a)" & "b)" in solution does not indicate twins but fakes PDB into showing the full solution.
Henrik Juel: Good attempt, Andrew
But there is no mate after 1... Kd7
Maybe adding wSf8 would help
Popeye does not do Rex Multiplex, and I believe it ignores
k and p in "cond prom k r b s p" (2019-01-15)
Henrik Juel: Sorry, I used 1.a8=K
Very good, Andrew (2019-01-15)
A.Buchanan: Thanks Henrik. Popeye does accept both k and p in cond prom. For p, it just shifts the pawn to the 8th rank without promotion. (2019-01-15)
