  21   Queens, rooks, bishops and knights begin the game in a reserve below
  22   the board, because their location isn't determined yet.
  23   At each turn, you can either move something already defined on the board, or
  24 ol
  25   li move a piece from your reserve to any question mark, and then
  26   li move the now defined piece on the board.
  27
  28 p An undefined piece gives check if some specialization giving check exists.

  38   At the first move, you must select a square for the king anywhere on
  39   the first rank &mdash; preferably in a corner. This deviates from the
  40   original intention of the author, but this way you will not need to castle
  41   later in the game. Click on a square to place the king.

  44   If after your move all your pieces are defined (and weren't before), then
  45   all pieces on board revert to undefined state, unless:
  46 ul
  47   li.
  48     all your pieces (board + reserve) are now of the same type,
  49     in which case none is put back in reserve, or
  50   li.
  51     all opponent's pieces are of the same type, in which case
  52     they also remain defined.

  63   If one of your undefined pieces is captured, you first have to choose which
  64   one was captured from the reserve: place it at the capture location.
