The solution

61.♔︎xd2! (not 61.♖︎xd5? ♔︎c6 62.♖︎xd2 ♘︎c4 =) 61…♘︎c4+ (if 61…♔︎b6 then 62.♔︎d3 ♔︎b7 63.♔︎d4 +−) 62.♔︎c3 (not 62.♔︎d3? ♘︎e5+ 63.♔︎c3 ♔︎b6 64.♖︎xd5 ♘︎c6 =) 62…d4+ 63.♔︎xd4 ♔︎b6 64.♖︎f5 ♘︎b2 65.♖︎f6+ +−

“hard to find”, “the natural move” and the rest describe how often this move is played by Maia-2, weighted across the 1500/1900/2000 audience the difficulty model is fitted on — a model of human play, not a count of anyone who solved this position.

Members can take this away as a PGN — the diagram, the verified line and their own analysis in one file, for a database, Anki or Chessable.
