Correct key by Popeye 4.61, but damaged by mate duals (2017-12-17)
SP: Anticipated by W. Linss, 395 Münchner Neueste Nachrichten 28/i/1895
(entry in the 2nd MNN tourney of 1893). The original composer avoided
the dual after the S underpromotion by using Pg4/Kh5 instead of Kg5.
His problem is quoted in Th. of PPromotion as well as contemporary
sources. (2022-12-12)

Henrik Juel: A joke problem, I see... (2022-09-12)
Mario Richter: Sorry, Henrik, I thought you've learned from the past that I sometimes can't resist to present a little trap. I was sure you would detect that popeye finds no solution to this seemingy simple position, but I expected that you - knowing me - would conclude that there must be something more about it (even more, since I presented it at Weekend). So I hope you can forgive me my little joke ... :-) (2022-09-12)
Henrik Juel: No problem, Mario
