+  | When a piece moves, the initial square disappears. It creates a 
+  a(href="https://en.wikipedia.org/wiki/Wormhole") "wormhole"
+  | .
+
+p.
+  Since all initial squares vanish, the board has exactly 64 - T squares
+  after T turns, so the game cannot last more than 32 moves.
+  Indeed a vanished square can be jumped over, but cannot be used again.
+  Holes are indicated with the letter 'x' on FEN strings.
+
+p.
+  In the diagram situation, the black knight can go to all the marked squares:
+  g5 and f6 are reachable because of the holes on f4 and e5.
+  Indeed the knight first moves one square vertically or horizontally,
+  and only then one square diagonally "in the same direction".
+  This is the only valid description in this variant
+  (others would lead to different knight movements around holes).
+  The black king can go to c6:
+  it moves to the closest non-vanished square (if any).

+  li.
+    The champion moves two squares in any direction,
+    or one square orthogonally.
+  li.
+    The wizard moves like an extended knight: two squares in an orthogonal
+    direction, and then one diagonal step. Or, a single diagonal step.
+  li.
+    The Murray Lion can move two squares in any direction.
+    He can also capture (only) by one square like a king.
+  li The other pieces move like in orthodox chess.
+p All pieces can jump over others when moving by two squares.
+
+h3 End of the game
+
+p Win by checkmate or stalemate: if you can no longer move, you lose.
