   2   | When a piece moves, the initial square disappears. It creates a

   6 p.
   7   Since all initial squares vanish, the board has exactly 64 - T squares
   8   after T turns, so the game cannot last more than 32 moves.
   9   Indeed a vanished square can be jumped over, but cannot be used again.
  10   Holes are indicated with the letter 'x' on FEN strings.

  12 p.
  13   In the diagram situation, the black knight can go to all the marked squares:
  14   g5 and f6 are reachable because of the holes on f4 and e5.
  15   Indeed the knight first moves one square vertically or horizontally,
  16   and only then one square diagonally "in the same direction".
  17   This is the only valid description in this variant
  18   (others would lead to different knight movements around holes).
  19   The black king can go to c6:
  20   it moves to the closest non-vanished square (if any).

  43     The champion moves two squares in any direction,
  44     or one square orthogonally.
  45   li.
  46     The wizard moves like an extended knight: two squares in an orthogonal
  47     direction, and then one diagonal step. Or, a single diagonal step.
  48   li.
  49     The Murray Lion can move two squares in any direction.
  50     He can also capture (only) by one square like a king.
  51   li The other pieces move like in orthodox chess.
  52 p All pieces can jump over others when moving by two squares.
