Henrik Juel: White promotes to L on c8 and g8; and these LL switch place, only to be captured

The Qa4 and the Bc4 attacks both Kings, so those two pieces have the same color and there was a discovered check. The only possible discovered check is a5xb6+ en passant, so Kb3, Qa4, Bc4 and Pb6 are white while Ka6 is black.
To have the en passant capture, black must have played b7-b5 and we deduce from it that Rc6 is black.
Before black has played b7-b5, the BKa6 was attacked by the WBc4, or it can not have moved, so there was a discovered check of this WBc4, and the only possible discovered check is with Rd5 which is then white.
Last two single moves are: n.a5xb6+ e.p. and n-1... b7-b5
Henrik Juel: The solution text is full of file errors
The retroplay is 1.a5xb6ep+ b7-b5 and e.g. 2.Tb5-d5+ (2021-12-24)
