Rules of Kamikaze Mortal Shogi
Kamikaze Mortal Shogi is played like Shogi except for the introduction of the Kamikaze piece and the rules concerning captures and promotions.
Pieces
Kamikaze Mortal Shogi uses the following pieces, which are arranged in order of descending rank. When a piece is captured, it demotes to the next lower ranking piece.
 King |
A King can move one space in any direction, so long as it does not move into check, just as in Western Chess. It does not promote. The object of Kamikaze Mortal Shogi is to checkmate the enemy King. |
 Dragon King |
The Dragon King is the promoted Rook. It moves as a Rook or one space diagonally. |
 Dragon Horse |
The Dragon Horse is the promoted Bishop. It moves as a Bishop or one space orthogonally. |
 Rook |
A Rook moves exactly as in chess, i.e. any number of squares on a rank or a file. It may not leap over other pieces. It promotes to a Dragon King. |
 Bishop |
A Bishop moves exactly as in chess, i.e. any number of squares on a diagonal. It may not leap over other pieces. It promotes to a Dragon Horse. |
 Gold General |
A Gold General moves a single space in any direction except diagonally backwards. It does not promote. |
 Silver General |
A Silver General moves a single space straight ahead or diagonally. It may promote to a Gold General. |
 Lance |
A Lance moves any number of squares, but only directly forward. It may promote to a Silver General or a Gold General. |
 Knight |
A Knight leaps over pieces as in Western Chess, but it is limited to forward motion: it leaps forward two squares and over one square to the left or right. It may promote to a Lance, a Silver General, or a Gold General. |
 Pawn |
A Pawn moves a single square forward at a time. It captures forward, just like it moves. It may promote to a Knight, a Lance, a Silver General, or a Gold General. |
 Kamikaze |
A Kamikaze leaps two spaces forward. It may promote to a Knight, a Lance, a Silver General, or a Gold General. It may not promote to a Pawn. Any captured or capturing Kamikaze disappears from the game. |
Some Shogi pieces are not used in this game. These are the promoted forms of the Pawn, Knight, Lance, and Silver General. The new piece is the Kamikaze. It leaps two spaces directly forward. If it captures a piece or is captured, it is removed from the game instead of being put in hand.
Captures
Whenever any piece but a Kamikaze is captured, it demotes to the next lowest ranking piece, following the order shown above. This replaces the rule in Shogi that promoted pieces demote back to their unpromoted forms. After demotion, a captured piece changes sides and is held in hand by the capturing player, who may drop it on a subsequent turn. When a Kamikaze is captured, it disappears from the game, as do captured pieces in Chess or most any other variant. A Kamikaze also disappears from the game when it captures a piece.
Promotions
As in Shogi, certain pieces may promote by entering, exiting, or moving within the promotion zone, which is for each player the last three ranks from his own perspective. The pieces that may promote are the Kamikaze, Pawn, Knight, Lance, Silver General, Bishop, and Rook. With the addition of the Kamikaze, this is the same as in Shogi. As in Shogi, Bishops promote to Dragon Horses, and Rooks promote to Dragon Kings.
Unlike Shogi, Kamikaze Mortal Shogi does not distinguish between Tokins, promoted Lances, promoted Knights, and promoted Silver Generals. Instead, when any piece lower ranking than a Gold General has the opportunity to promote, it may promote, with one exception, to any higher ranking piece up to and including a Gold General, provided there are spaces remaining on the board that it could legally move to as the piece it promotes to. So, nothing may promote to a Lance once it reaches the last rank, and nothing may promote to a Knight once it reaches either of the last two ranks. The one exception is the Kamikaze, which may not promote to a Pawn.
Dropping
Dropping rules are just the same as in Shogi. With certain restrictions, a piece may be dropped on any empty space. An obvious restriction on any drop is that the resulting position must be legal. A second restriction on each piece, though applicable to only a few, is that there must be spaces remaining on the board to which it could legally move. Thus, Pawns and Lances may not be dropped on the last rank, and Knights and Kamikazes may not be dropped on either of the last two ranks. Finally, there are a couple more restrictions for dropping Pawns. First, a Pawn may not be dropped in any file that already has a Pawn belonging to the same side. Second, a Pawn drop may never be used to checkmate the enemy King.
Miscellaneous
As in Chess, the object is to checkmate the enemy King. Unlike Chess, Black moves first.
Notation
This preset automatically handles the processing of captured pieces, and it allows you to drop a captured piece without specifying the off-board location of the piece. The two files on each side of the board are off-board areas for storing captured pieces. The area is shared by both players, but you each begin using it from a different end. Your area begins at the space to your bottom right. When you capture a piece, it is automatically sent to the first empty space in the off-board area, then its side is changed, and then it demotes. All of this is handled automatically, and all you need to include in the notation for your move is a move from one space to another. Although each off-board position has a coordinate, you may ignore these coordinates by using the * operator to drop a piece. To use the * operator, enter the notation for the piece, an asterisk, and the destination. It will then move the first piece it finds of that sort to the designated location. For example, b*5e would drop a Black Bishop on 5e. Be careful to use the proper case for your pieces. If you are playing Black, you should use lowercase notation for your pieces. If you are playing White, you should use uppercase notation for your pieces.
This preset enforces the rules of Kamikaze Mortal Shogi. If it lets you make an illegal move or doesn't let you make a legal move, please inform Fergus Duniho.
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.
These pieces were made by Fergus Duniho, using a Japanese font and some sample images of wood.

Kibbitzing Etiquette
Kibbitzing is the practice of commenting on a game you are not playing. In commenting on a game, please follow these rules of etiquette.
(1) If you notice that someone has made an illegal move, please mention it. Some Game Courier presets cannot enforce rules, but Game Courier does enable players to take back any previous move. Details on how to take back a move are provided in the User's Guide, linked to above the board.
(2) Unless otherwise specifically asked to, do not offer hints or suggestions to players on what moves they should make. In general, avoid coaching comments.
(3) Once a game is over, it should be alright to offer your analysis of the game and your specific comments on what moves players should have made. If some players don't want this, they may mention it in the Kibbitzing section, and you should honor this request by not commenting on the game.
(4) Be polite. At the appropriate time, offer any criticism you have in a constructive manner. Avoid heckling players for bad moves.
(5) Don't spam this space with irrelevant comments. If you have a comment about Game Courier, rather than about the specific game you're viewing, please post it on Game Courier's Index page to give it.
