R: 1. c7-c5! Kd3-e3 2. Dc6-c4+ Ke3-d3! clear
Easy to see no last move for White. Moreover, Black just double-hopped to allow sD/wK to avoid retro-loop.
Single clean retro try.

Black can have wasted only one move and so cannot have moved K or KR, which would require a second waste move returning to diagram. Hence Black is legally entitled to castle. Therefore White mates in 2 by: 1. Kh1! 0-0-0 2. Tc1, else 2. Tg8

Position after White’s 25th move.
Can Black play to avoid being mated in 2?
But both b3 and Rc8 seem to let Black escape (2023-04-06)

Analysis
White is missing one man, so last move was not a pawn capture
White pawns captured all six missing black men, so last move was not d7-d5
Obviously last move was not made by Ke7 or Sd8f8, so last move was f7-f5 legitimizing the ep key (2020-11-02)

msterkowiec: I think it's worth noting that apart from minor dual 4.Qf2/Qg2 there are also some other duals in subsequent moves:
1) 6. Qc6 lub 6.Qb7 (this repeating manoeuvre can be done both via c6 and b7)
2) 7. Qa6+ lub 7.Qa4+ (this repeating manoeuvre can be done both via a6 and a4) (2021-11-20)

Nach 1.Kc1 ... 6.a8=D Kb5! braucht Weiss noch 48 Züge bis zum s#.
Mit der Stellungsveränderung sBc7 nach c5 ist es ein s#45 (mit den bei Blathy üblichen Dualen) (2020-11-14)
