James Malcom: This is a most excellent problem! En passant as the key and a double pickaninny in a short s#2 is surely no easy feat, I'd say. Now, question: Why can't dxc5 be Black's last move? The illegal retraction od b6-b7 is already quite obvious. (2020-10-24)
A.Buchanan: R: 1. cxb6/dxc5? both imply 3 pawn captures by Bl (2020-10-24)
A.Buchanan: I agree this is a beautifully integrated composition (2020-10-24)

Henrik Juel: set play 1... Sxc1/Sxc3/Sxb4 2.Txc1/Txc3/Dxb4 Lxg7#
solution 1.cxd6ep+ Sxc3 2.d7 Lxg7#
Last move was not c4xd3 or e4xd3 (on a light square), because the missing white man is the dark-squared [Lc1], so it was d7-d5, legitimizing the ep key (2021-10-03)
A.Buchanan: Sound + lighter + W2 becomes sole viable tempo move (with 10 other White pieces able to move). (2021-10-04)
