C+ Euclide 1.11 in 44 Std. 07 Min. (2023-01-10)
A.Buchanan: This is a cool problem with tempo loss for both players (bK9 & wPf2). Noam likes to end proof games with checkmate, and in this case I guess it serves to eliminate shorter solutions which would otherwise save half a move. Checking 16.5 is sufficient for soundness. Thanks for taking the time to test. (2023-01-11)
A.Buchanan: Bit baffled how there can be 64 solutions in 18.0 moves since White just moved. 18.5 maybe? (2023-01-11)
ras@bsiag.com: Quickly checked because 45h seemed a lot for only 17.5 moves and only a few captures: Stelvio 0.98 is done in 210 seconds. (2023-01-11)
ras@bsiag.com: Well, Stelvio treats shorter solutions of same parity as cooks, so any shorter solution in 16.5, 15.5 etc would have been found by checking for 17.5. But anyhow, quickly checking 16.5 is done in a few seconds, finding no solution (of course). (2023-01-12)

1. d7! and e.g. d3 2. d8=L b5 3. a8=S gxf5 4. g8=D h2 5. h8=T h1=D 6. Txh1 dxc2 7. De6+ Lxe6#
Author's Note: Black can play d3, b5, gxf5, and h2 in any order, with corresponding White promotions as replies, giving all 24 permutations of White AUW (LSDT, LDST, etc.). If Black plays g5 instead of gxf5, then White replies fxg5 instead of promoting to D. A white pawn added at g5 would eliminate this pesky variation, but the white pawns are all used up!

SCHRECKE: Unlösbar, eventuell fehlt ein wBf4. (2020-10-28)
A.Buchanan: Mark Kirtley wrote to me: George found the original issue of the U.S. Problem Bulletin, showed me, and yes, there is a wPf4 in the original. George and I couldn't remember why we also had a wPa2, but a new computer test (Gustav) showed us the reason: it guards against a major dual Rh1-a1 in some variations.
There is still a minor dual in some variations (of varying length) if the bP promotes to a Q at h1, for then wRh8-h6+, bQh1xh6, and wQe6+ and bQxe6#. (2020-11-11)
A.Buchanan: So I have corrected the confirmed diagram typo (2020-11-11)
A.Buchanan: Have posted a simplified representation of the solution, at the author's request (2021-01-27)
Henrik Juel: So the problem is C+, except for the minor dual mentioned (2021-01-27)

Wilfried Neef: Den Preisbericht von damals habe ich nicht mehr, aber Band 11 der weinroten Reihe "Yakov Vladimirov, Selected Problems, Moskau 2015" Bestätigt MR, dürfte korrekt sein und damit als legitimer Turniersieger von 1994 gelten. (2023-01-11)
