8 Paco-Sako was invented by Felix Albers in 2017, and further developped

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 Castling is forbidden if a direct or "chained" attack exists on any square
74 in the king's path. However, direct or chained attacks on the king are
75 otherwise ignored: you can run or remain into "check".

84
85 p.
86 I added some small changes, globally to complicate defense.
87 These are not in the official rules.
88 To disable them, check the box "pacoplay mode".
89
90 ul
91 li.
92 Canceling an union move is forbidden. For example if a bishop is
93 dancing with a queen, and makes the move e5 to g3, the other player
94 cannot move it back to e5 just after.
95 li.
96 Pawns (or pawns in unions) can advance two squares from their initial
97 position, but you may only do that once per file.
98 li.
99 If you form an union with your king but end dancing with the
100 other king on the other end of the chain, the game is a draw.
