2 Pieces generally move like an orthodox queen,
3 but capture according to complexe rules.

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

11 h4 Pieces names
12
13 p Pieces names refer to the way they capture, which is described later.

15 li Pawn : Cannon Pawn
16 li Rook : Swapper
17 li Knight : Long Leaper
18 li Bishop : Vhameleon
19 li Queen : "Pushme-Pullyu"
20 li King : King (same behavior as in standard chess)
21 p.
22 Besides, a new piece is introduced: the immobilizer, written by the letter
23 'M'. It is represented by an upside-down rook:

30 p The board is of size 10x10 to facilitate captures, as explained below.
31
32 h3 Non-capturing moves
33
34 p The king moves (and captures) as usual.
35
36 p.
37 Cannon Pawns move without capturing two ways: either a single step in any
38 direction, or, they may leap over an adjacent piece of either side to the
39 empty square just beyond.

45
46 p All other pieces move like an orthodox queen.
47
48 p.
49 When a piece is next to an enemy immobilizer, it cannot move but
50 is allowed a special "suicide" move: it can disappear by "capturing" the
51 immobilizer (to trigger the move on the interface).
52
53 h3 Capturing moves
54
55 p.
56 As said above, the king captures as usual. However, all other pieces have
57 a new way of capturing - when they can. Indeed the immobilizer doesn't
58 capture, and the swapper can only capture a piece when it stands next to him.
59 In this case he disappears as well in the process.
60
61 p.
62 The edge of the board can be reached only by capturing, only if landing on
63 the edge is the only way to do some capture, and that there exist no other
64 such captures with a smallest move length. The move length is the distance
65 between the initial and destination squares.

67 h4 (Cannon) Pawns
68
69 p.
70 Cannon pawns capture by leaping over an adjacent piece (the mount), landing
71 on the opposing piece just beyond the mount.

78 h4 "Pushme-Pullyu" (Queen)
79
80 p.
81 The queen captures on the square just after where she stops (if any
82 opponent's piece stands there), and also on the square initially just behind
83 her. It is a combination of a Withdrawer and an Advancer, as described on
84 the rules page on chessvariants (see the link at the bottom).

90 Any move to the right will capture the bishop; only a move to the marked
91 spot will also capture the rook.
92
93 h4 Rook (Swapper)
94
95 p.
96 The rook can swap its position with any enemy piece in the attacking
97 line of an orthodox queen, as illustrated below.

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

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

119 h3 End of the game
120
121 p.
122 The game ends by checkmate or stalemate as in standard chess.
123 Just pay attention to the capturing rules :)
