As reported by Chrilly Donninger [12], Nimzo happily sacrificed the knight with 61... Nxb7, winning the game due to a bug. A winning score was given, applying the Rule of the Square for its black passer. Instead, as intended, with White having no pieces to make the e-pawn unstoppable, the winning score was enabled by Black without pieces [13]!
