+
+p.
+ At the very first move, players may decide to swap positions of adjacent
+ knights and bishops. Either on both sides, or on one only. To bypass this
+ step (or end it after a first swap), move your king to the opponent's king.

+
+p.
+ Known pieces move as usual, with one exception: the pawn only promotes
+ to a queen (named "Gilding" in this game). Additionally, all pieces can
+ promote — except queen and king:
+ul
+ li Rook promotes into Dragon = Rook + King.
+ li Knight promotes into Scepter = Knight + King.
+ li Bishop promotes into Horse = Bishop + King.
+ li Cardinal promotes into Queen (called "Whole" here).
+ li Marshal promotes into Queen (called "Apricot" here).
+p.
+ All these promotions are optional. They are available after a move ending
+ at or starting from the last two ranks.
+
+p.
+ Each captured piece is first returned to its unpromoted version (if
+ applicable), and then added to a reserve. It can be dropped later
+ in place of a move.
+
+h3 Some details
+
+p.
+ Pawns can initially advance three squares.
+ On the third rank, they can still advance two squares.
+ A dropped pawn cannot give checkmate.
+
+p While castling, the king moves three squares lateraly.
+
+p.
+ Threefold repetition is a draw, unless caused by a perpetual check.
+ In this case, the player giving check loses.
