Schwarz hat zuletzt f7-f5 gezogen, da d7-d5 an der retrograden Einsperrung des Lc8 scheitert.
Henrik Juel: C+ Popeye 4.61 after analysis
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)
