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

  71 h3 Stalemate or checkmate?
  72
  73 p.
  74     The following diagram seems to show a mating pattern, but the king if
  75     "attacked" by a checkered pawn &ndash; which still belongs to white.
  76     Therefore, it can be considered that it's not really a check because
  77     white is unable to "give back the turn".
  78     Without the black bishop on a7 it would be mate (without debate), because
  79     the king could virtually go to g1 before being captured by the pawn-chamaleon.

  87     The interface considers that it's mate in both cases, following the idea
  88     "it's checkmate if we cannot move, and the opponent on its turn could
  89     take the king" (maybe after an impossible move).

  95 p.
  96     During the game one of the two players can decide to take control of the
  97     checkered pieces.
  98     They thus become autonomous and vulnerable to being captured - stage 2 begins.
  99     The other player is in charge of both the white and black pieces, and tries to
 100     eliminate checkered pieces.
 101     The checkered side wins by checkmating either the white or black king.

 103 h4 Variant of stage 2
 104 p.
 105     An observer could decide to join the game by taking the checkered pieces
 106     at any moment.
 107     It then becomes a chess game with three players, with some subtelties to be resolved.
 108     It was tested in some (real life) games organised by the variant creator.
