Mario Richter: Does Henrik's answer show that the problem is cooked? (2022-09-12)
Henrik Juel: Yes, Mario (2022-09-12)
A.Buchanan: Could it be that bRb6 is meant to be on a6? (2022-09-13)
A.Buchanan: The point being that with bRa6, 1. d8=sL? La5! (not Lc7/Lb6 2. Sd7#/Te6#) So bishop promotion becomes a thematic try. (2022-09-13)
Mario Richter: I have access to the original issue of 'Shakhmatna Misl', so I can confirm that the black rooks are on a7 and b6. I checked some of the following issues to see, if there was a mentioning a of the cook and/or a correction, but without success.
Changing the cook 1. d8=sL! into a try would be nice, but I think the purpose of black Tb6 is to prevent the defense 1. ... Db3!, so unless I'm missing something, Andrew's suggestion doesn't work. (2022-09-13)
A.Buchanan: Thanks Mario - I didn't check enough. If further one swaps bQb8 with bRa7, and pushes wK to h2 further out of harms way, then I think the =S solution & =L try are sound: 1r6/q2Pp1P1/r4k1N/2N3R1/5p1P/8/4R2K/8 (2022-09-13)
James Malcom: Nice find, Mario; sweet fix, Andrew. (2022-09-14)
A.Buchanan: Thanks James. r7/q2Pp1P1/r4k1N/2N3R1/7P/8/8/4RK2 further saves a pawn and has better positions for the remote units. I suggest attribution is MM correction HJ,MR,AB. (2022-09-15)
A.Buchanan: Alternatively r7/q2Pp1P1/r4k1N/2N3R1/5p1K/8/8/4R3 economizes a wP rather than a bP. I don't know which version my esteemed co-creators would prefer to record this momentous achievement for posterity. I don't see a way to reach Meredith (2022-09-17)

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
And Michael saw the trick (2022-09-12)
