1. N:b2# Black's last move was a3:b2. White's balance equals 12 in the diagram) + 4 (captures d:c:b4:a3:52) = 16 - including the pawns e2, 12, g2 and h2, which were promoted. Black's balance: 9 (in the diagram) + 7 (captures e:d7-d8, f:e7-e8, g:f:e7-e8, h:g:f:e7-e8) = 16. Retroplay: 1. ... a3:Qb2 (necessarily a Queen!) 2. Na2-b4! b4:Ba3 (necessarily a Bishop) 3. c4-c5 c5:Nb4 (necessarily a Knight) 4. Qal-b2 d6:Rc5 (necessarily a Rook) 5. Bcl-a3 Ka36. Rb2-b3++! Ka4-a3 7. Bb1-c2+, etc. Had Black uncaptured a Rook on b2, then the retromove 4. Rb1-b2 instead of Qal-b2) would have oscillations of the black King on the squares a3-a4 and the white Rook on b2-b3 would have gone on forever... This is the first-ever rendition of uncapture differentiation under the pressure of perpetual retro motion!

Preisbericht "Kofman-75" in 'Schachmaty w SSSR' 10/1984, S. 31-32, PR: R. Kofman

Michael Herzberg: Sehr gelungene Darstellung einer Idee von L.Loshinsky, V. I. Shif, siehe P1044406 (2022-03-21)
Henrik Juel: C+ Popeye 4.61, except for late duals after 1... g2,g5 (2022-03-21)
Michael Herzberg: 1…g2 2.Dg1 Tc2+ 3.Sxc2 ~ 4.Dh2#/Dd4# ; 1…g2 2.Dg1 Txe3 3.Dxe3 ~ 4.d4#/Dd4#/Df4#/Dg5#; 1…g5 2.Df1 Tc2+ 3.Sxc2 ~ 4.Df5#/Df6#/Lf6# ; 1…g5 2.Df1 Tb3+ 3.Kxb3 ~ 4.Df5#/Df6#/Lf6#

Die Duale der Nebenvarianten im Mattzug sind sehr unschön, können aber verhindert werden, indem die Konstruktion erweitert wird. Wahrscheinlich sind auch die vollzügigen Nebenspiele der Grund, warum dieses thematisch sehr gute Problem nicht im FIDE-Album gelandet ist?!
Ich habe Alexander Kuzovkov folgende Stellungen im März 2023 zukommen lassen, welche ich
dem Fachpublikum nicht vorenthalten möchte.

W:Kc1,Db1,Lf7,Le7,Sf3,Sf6,Bc6,Bd5,Be2,Bh4. (10)
S:Kf5,Da7,Tc8,Td3,Lb5,Ba4,Bb6,Bc4,Bc7,Be5,Bf4,Bh7,Bh5. (13)
#4 C+
1.Kc2! (2.Le6+ Kg6 3.Dg1+ Kh6 4.Dg5#) 1...Txd5 2.Kc1+ Td3 3.Sd4+ exd4 4.Dxb5# ; 1...Txf3
2.Kb2+ Td3 3.e4+ fxe3 e. p. 4.Df1#

2 Steine mehr gegenüber dem Urproblem, keine vollzügigen Nebenvarianten, aber der Autor muss entscheiden, ob dieser Materialmehraufwand gerechtfertigt ist.
Wenn auf den guten Schlüssel verzichtet wird, ist sogar eine sparsame Version möglich, auch das Schlagen des sL im Mattzug entfällt. Das Stück und die Idee werden dann allerdings etwas „entwertet“, da gerade der Schlüssel zum Thema gehört und einen besonderen Reiz in Verbindung mit den Varianten ausmacht. („Königstepps“)

W:Kc2,Db1,Ld8,Lf7,Se1,Sf6,Ba3,Bd5,Be2,Bg6,Bh4. (11)
S:Kf5,Ta4,Td3,Bb6,Bc4,Be5,Bf4,Bh7,Bh5. (9)
