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!

A.Buchanan: If WTM, no solution, but since no legal last move for Black, we let Black start:

The play is so savagely dualized, that one must marked it as cooked. Typo? (2023-12-04)
