Tiger Chess

If this looks different than the preset you clicked on the Edit button for, this is because that was a customization, and this is for editing the settings file that customization was based on. This form is for defining the game and for giving it a default appearance. You should define a game only once, then go back and click on the Customize button to provide options for how the game looks. Changing the Settings Name will create a clone of this preset that will not inherit subsequent bug fixes or improvements made to it. If all you want to do is change the appearance, go back and click on the Customize button

All rules are as in Chess except for castling and pawn promotion. Instead of castling, the King may leap up to three squares away if he hasn't moved yet and is not in check. Pawns promte immediately on reaching the opposite pawn rank to whichever piece begins on that file, or to a Queen on the King's file.

The Tiger leaps as a zebra and may then slide outward as a bishop.

The Pegasus leaps as a knight and may then slide outward as a rook.

The Astrologer leaps as a camel and may then slide outward as a bishop.

To enable moving by mouse or touch, you should enable JavaScript. Even without JavaScript enabled, you can still move pieces by entering your moves in the Moves field, using 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.

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.

The inclusion of a piece does not indicate that it is used in the game you are playing. But if your game uses pieces not included here, you should choose a different piece set.

This preset uses the tiger settings file for Tiger Chess, which was made by Daniel Zacharias.

I'm having some issues with programming a game courier preset for a game that I'm working on. It is exhibiting behavior that I don't quite understand. Here is the link to the entry, including the rules for how the game is supposed to work.

With the fix I made to unless, described here, this can all be done with one line:

setsystem legalmoves aggregate lambda (#0 unless == #0 "P e2-e4") $legalmoves;
