23 | There are no captures in this game: only unions of pieces, | |
24 | which are released when replaced by another friendly piece. | |
25 | The goal is to create an union with the enemy king. | |
26 | I like to think of unions as "pieces dancing together", so both | |
27 | terms will be used on this page. | |

37 | At each turn, a player chooses either one of his pieces or an union piece; | |
38 | let's write this piece A. | |
39 | ul | |
40 | li. | |
41 | Case 1: A is a dancing piece. Then, it's only allowed to move | |
42 | to a vacant square according to our piece's type. | |
43 | li. | |
44 | Case 2: A is a standard piece. | |
45 | It can then be moved anywhere but on our own (normal) pieces. | |
46 | "Capturing" an enemy piece creates an union composed of both pieces. | |
47 | "Capturing" an union releases our piece formerly in union, | |
48 | which has to be moved immediately by the same player. It can in turn | |
49 | release another piece, thus following a chain of unions. | |

73 | Attacks on the king are ignored in this implementation: you can run | |
74 | or remain into "check". So, castling conditions are quite permissive. | |
75 | Also, if you form an union with your king but end dancing with the | |
76 | other king on the other end of the chain, the game is a draw. | |
77 | span.warning This does not follow (at all) the official rules. | |

88 | Canceling an union move is forbidden. For example if a bishop is | |
89 | dancing with a queen, and makes the move e5 to g3, the other player cannot | |
90 | move it back to e5 just after. This is also non-official. | |
