p.boxed.
  Pieces generally move like an orthodox queen,
  but capture according to complexe rules.

p.
  This variant comes from an attempt to fix some issues with Baroque variant,
  which "favors the defense over the attack, and is lacking in clarity"
  (from the introduction of the Rococo rules; see the link at the bottom of
  the page).

h4 Pieces names

p Pieces names refer to the way they capture, which is described later.
ul
  li Pawn : Cannon Pawn
  li Rook : Swapper
  li Knight : Long Leaper
  li Bishop : Vhameleon
  li Queen : "Pushme-Pullyu"
  li King : King (same behavior as in standard chess)
p.
  Besides, a new piece is introduced: the immobilizer, written by the letter
  'M'. It is represented by an upside-down rook:

  figcaption Immobilizers on e3 and f7.

p The board is of size 10x10 to facilitate captures, as explained below.

h3 Non-capturing moves

p The king moves (and captures) as usual.

p.
  Cannon Pawns move without capturing two ways: either a single step in any
  direction, or, they may leap over an adjacent piece of either side to the
  empty square just beyond.

  figcaption Squares where the pawn can move to (without capturing).

p All other pieces move like an orthodox queen.

p.
  When a piece is next to an enemy immobilizer, it cannot move but
  is allowed a special "suicide" move: it can disappear by "capturing" the
  immobilizer (to trigger the move on the interface).

h3 Capturing moves

p.
  As said above, the king captures as usual. However, all other pieces have
  a new way of capturing - when they can. Indeed the immobilizer doesn't
  capture, and the swapper can only capture a piece when it stands next to him.
  In this case he disappears as well in the process.

p.
  The edge of the board can be reached only by capturing, only if landing on
  the edge is the only way to do some capture, and that there exist no other
  such captures with a smallest move length. The move length is the distance
  between the initial and destination squares.

h4 (Cannon) Pawns

p.
  Cannon pawns capture by leaping over an adjacent piece (the mount), landing
  on the opposing piece just beyond the mount.

h4 "Pushme-Pullyu" (Queen)

p.
  The queen captures on the square just after where she stops (if any
  opponent's piece stands there), and also on the square initially just behind
  her. It is a combination of a Withdrawer and an Advancer, as described on
  the rules page on chessvariants (see the link at the bottom).

    Any move to the right will capture the bishop; only a move to the marked
    spot will also capture the rook.

h4 Rook (Swapper)

p.
  The rook can swap its position with any enemy piece in the attacking
  line of an orthodox queen, as illustrated below.

  figcaption Before and after a rook swap with the king.

p.
  Moreover, if the rook stands just next to an enemy piece (like the knight
  here), it can choose to capture it by a "kamikaze" attack: indeed it get
  self-destroyed in the process.

h4 Other pieces

p.
  The Long Leaper, Immobilizer and Chameleon behave as in the Baroque
  variant playable on this site: please refer to these rules description. There
  is only one change is in the immobilizing rules, which are simpler here:
  immobilizers powers are not canceled by the chameleons.

h3 End of the game

p.
  The game ends by checkmate or stalemate as in standard chess.
  Just pay attention to the capturing rules :)
