Rules of 4 Kings Quasi-Shatranj
In this game there are 9 piece types (all short range), including 3 types from standard chess (i.e. Pawns, Knights and Kings). All of the other 6 types are compound pieces (with names as per wikipedia):
Alibaba: leaps like an alfil (2,2) {aka Persian elephant} or dabbaba (0,2) {aka war machine}, that is leaps 2 squares diagonally or 2 squares orthogonally - note that this piece type is colour-bound, and has an additional form of binding (i.e. to even or odd numbered ranks & to even or odd numbered files);
Modern Elephant: leaps like an alfil or ferz (1,1), that is leaps 2 squares diagonally or 1 square diagonally - note that this piece type is colour-bound;
Waffle: leaps like an alfil or wazir (0,1), that is leaps 2 squares diagonally or 1 square orthogonally;
Kirin: leaps like a dabbaba or ferz, that is leaps 2 squares orthogonally or 1 square diagonally - note that this piece type is colour-bound;
Wazaba: leaps like a dabbaba or wazir, that is leaps 2 squares orthogonally or 1 square orthogonally;
Guard: moves like a King, that is like a ferz or wazir, i.e. 1 square diagonally or 1 square orthogonally {aka mann}.
A player wins if any of the opponent's Kings are checkmated. Note that if 2 or more of a player's Kings are in check, and not all of these can get out of check with any single next move by the player, that player is effectively checkmated.
If a player ever lacks legal moves, but none of his Kings are in check, then this is a stalemate, and the game is drawn.
Pawns move as in standard chess (i.e. an initial double step move and en passant captures are allowed), and in this variant may promote on the last rank to any of the piece types in the setup, except for King.
There is no castling.
Threefold repetition of position is a draw as in standard chess, and the 50 move rule is also in effect (i.e. game drawn if no captures or pawn moves have been made before 50 consecutive moves by both sides).

How to Move Pieces
Full Algebraic Notation
Algebraic notation identifies each space by a coordinate that begins with its file label and ends with its rank label. On the Chess board, files go up and down from one player to the other, and ranks go from left to right. In most games, files are represented by letters, and ranks are represented by numbers, but there is no fixed rule requiring this for all games, and some games, such as Shogi, reverse this convention. If you look at the diagram, you will usually see the file labels going from left to right and the file labels going up and down. And if you hover your mouse over a space, you will normally see the name of the coordinate appear in a tooltip.
It is not uncommon to see algebraic notation being used for Chess, but it is often in an abbreviated format that requires you to know both the rules of the game and the current position to know exactly which piece moves where. For example, the notation "Ne6" indicates that a Knight is moving to e6, but it doesn't indicate which Knight, and it doesn't specify where the Knight is coming from. To figure this out, you need to know how a Knight moves and which Knight on the board can make a legal move to e6.
Although rules may be programmed for individual games, Game Courier itself does not know the rules of any game, and it is unable to parse abbreviated algebraic notation. Therefore, it relies on full algebraic notation, which completely specifies the move without requiring any knowledge of the game's rules or the current position. The most usual type of full algebraic notation indicates the piece that is moving by its label, the space it is moving from, and the space it moving to. In Chess, a typical first move might be written as "P e2-e4". When you hover your mouse over a piece, you will normally see the piece label followed by the coordinate for the space, and when you hover it over an empty space, you will normally see the coordinate label. Including the piece label in your notation allows Game Courier to check that the piece you're moving is the right one, and it makes game notation easier to follow, but it is not mandatory.
You may promote a piece by including a promotion move after your regular move. A promotion move has a piece go directly to a coordinate. Here is an example: "p e7-e8; q-e8".
You may remove a piece from a space by adding an @ to the space or by omitting the destination coordinate. For example, both "@-e4" and "e4-" would remove the piece on "e4". This is useful for en passant when you are playing a game that does not handle this automatically. For example, "P d5-e6; e5-" removes the Pawn on e5 after a Pawn moves from d5 to e6.
You will not need to remove spaces for most games, but if you should need to, you can do this by omitting the first coordinate in a move. For example, "-e4" would remove e4 from the board. To add or return a space to the board, you may add an @ or any other piece to it.
Available Pieces
Pieces are represented by labels, usually using uppercase letters for White and lowercase letter for Black. When you enter a move or specify the starting position for a game, you should remember that piece labels are case-sensitive. Many piece sets are available for use with Game Courier, and this table shows you which pieces belong to the piece set you are currently using.
These pieces come from a set containing more pieces, but this preset has had the set of pieces reduced to those used in the game.
