  26     | The new piece arising from a capture has a new color:

  34   li.
  35     A non-capturing checkered move cannot be "undone" right after since
  36     this would repeat the same position.

  50     Pawns can jump two squares only from their initial rank, and only once in the game:
  51     a checkered pawn returning on the pawns' start rank cannot jump. However:
  52   li.
  53     A pawn captured on its starting square (thus becoming "checkered") keeps the
  54     right to advance two squares.
  55   li.
  56     Checkered pawns cannot capture en passant, because while the pawn was "passing"
  57     they were of the same color.

  61 h3 Stalemate or checkmate?
  62
  63 p.
  64   The following diagram seems to show a mating pattern, but the king if
  65   "attacked" by a checkered pawn &ndash; which still belongs to white.
  66   Therefore, it can be considered that it's not really a check because
  67   white is unable to "give back the turn".
  68   Without the black bishop on a7 it would be mate (without debate), because
  69   the king could virtually go to g1 before being captured by the pawn-chamaleon.

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

  85 p.
  86   During the game one of the two players can decide to take control of the
  87   checkered pieces.
  88   They thus become autonomous and vulnerable to being captured - stage 2 begins.
  89   The other player is in charge of both the white and black pieces, and tries to
  90   eliminate checkered pieces.
  91   The checkered side wins by checkmating either the white or black king.
  92
  93 h4 Variant of stage 2
  94 p.
  95   An observer could decide to join the game by taking the checkered pieces
  96   at any moment.
  97   It then becomes a chess game with three players, with some subtelties to be resolved.
  98   It was tested in some (real life) games organised by the variant creator.
