  44         A non-capturing checkered move cannot be "undone" right after since

  59         Pawns can jump two squares only from their initial rank, and only once in the game:
  60         a checkered pawn returning on the pawns' start rank cannot jump. However:
  61     li.
  62         A pawn captured on its starting square (thus becoming "checkered") keeps the
  63         right to advance two squares.
  64     li.
  65         Checkered pawns cannot capture en passant, because while the pawn was "passing"
  66         they were of the same color.

  72 p.
  73     During the game one of the two players can decide to take control of the
  74     checkered pieces.
  75     They thus become autonomous and vulnerable to being captured - stage 2 begins.
  76     The other player is in charge of both the white and black pieces, and tries to
  77     eliminate checkered pieces.
  78     The checkered side wins by checkmating either the white or black king.
  79
  80 h4 Variant of stage 2
  81 p.
  82     An observer could decide to join the game by taking the checkered pieces
  83     at any moment.
  84     It then becomes a chess game with three players, with some subtelties to be resolved.
  85     It was tested in some (real life) games organised by the variant creator.
