===============
Tori Shogi is the smallest ancient member of the Japanese family of chess
games. The game dates from the end of the eighteenth century and is
attributed to Ohashi Soei, a famous master of Shogi.
Tori Shogi literally means 'Bird Chess' and all of the pieces are named
after birds.
Apart from Shogi itself (and possibly Wa Shogi), Tori is the only old
variant that is played with 'drops' (returning captured pieces into play),
a feature which adds greatly to the appeal and depth of strategy of the
game.
THE GAME
=========
Tori Shogi is played on a board of 7 x 7 squares and each player has 16
pieces.
As in all Shogi variants the pieces are flat and wedge-shaped and are not
distinguished by colour. Although the pieces are of uniform colour the
first player is still conventionally referred to as 'Black' and the second
player as 'White'. Ownership of the pieces is indicated by the direction
in which they face, with a player's pieces always pointing towards the
opponent.
The players make alternate moves, with the object being to capture the
opposing 'Phoenix'. When a 'Phoenix' is about to be captured next move
and no legal move can be made to prevent the capture, the piece is said
to be 'Checkmated'.
On each turn a player can either:
a) move one piece according to its power of movement to a vacant square
on the board, or to a square occupied by an enemy piece (in which
case the enemy piece is captured and removed);
or,
b) 'Drop' (re-enter) a previously captured piece on almost any vacant
square.
THE PIECES
===========
The Piece Help screen provides the names, notation symbols, promotion
details, and powers of movement for all of the pieces in the game.
[The Piece Help screen can be reached by clicking on the 'Pieces' button]
JUMPING PIECES
===============
The 'Goose' and 'Pheasant' are the only pieces in Tori Shogi that have the
power to jump over occupied squares. Both can jump to the second square
in the directions indicated with red circles on the Piece Help diagram.
The 'Eagle' can move to the second square in the reverse diagonal
directions only if the first square is vacant (ie: it can not jump).
PROMOTION
==========
Each player has a Promotion Zone consisting of the two ranks (rows of
squares) furthest away from him.
Whenever a 'Swallow' or 'Falcon' makes a move wholly or partly within the
Promotion Zone the piece assumes its promoted rank. The 'Swallow'
promotes to a 'Goose' and a 'Falcon' becomes an 'Eagle'.
It should be noted that unlike in Shogi, promotion is compulsory.
As in other Shogi games, in Tori sets the promoted rank is shown on the
reverse side of the piece, and the piece is turned over on promotion to
reveal the new rank.
CAPTURES
=========
A captured piece is removed from the board and is held by the capturing
player. The held piece (which is said to be 'in-hand') may subsequently
be 'dropped' back into play on the side of the player who made the capture.
'Eagles' and 'Geese' revert to their unpromoted ranks when captured.
DROPS
======
In place of a move a player may elect to 'drop' a piece held in-hand back
into play. Pieces other than 'Swallows' may be returned to play on any
vacant square.
The following restrictions apply to drops involving 'Swallows'. A Swallow
may not be dropped:
a) on the last rank (that furthest from the player),
b) in any file (column of squares) already containing two unpromoted
'Swallows' of the same side,
c) directly in front of the opposing 'Phoenix' so as to give instant
'Checkmate'.
A 'Swallow' or 'Falcon' that is dropped inside the player's Promotion Zone
is not promoted until after it has made a further move on the board.
REPETITION OF MOVES
=====================
If the same position occurs three times by repetition of moves, the player
starting the sequence must vary his move.
HANDICAP PLAY
==============
As in Shogi, a player of Tori may offer a handicap of one or more pieces to
an opponent of less strength.
The player giving the handicap plays 'White' and his opponent (as 'Black')
removes the handicap pieces as the first move of the game. In handicap
play 'White' therefore makes the first move on the board.
Pieces removed as a handicap are totally removed from play and are not
held in-hand by 'Black'.
NOTATION
==========
The following notation system is used for recording Tori games in this
program.
The files are designated by numbers (1 to 7), and the ranks by letters
(a to g). The files are numbered from right to left (in the Japanese
fashion), and the ranks from top to bottom (from Black's point of view).
The top right square is therefore 1a.
A move is described by giving:
a) the designation of the piece (eg: Sw for Swallow),
b) followed by the method of moving;
'-' for a simple move on the board,
'x' for a capture,
'*' for a drop,
c) then the destination square is recorded,
d) finally if the piece promoted, this is recorded by adding '+' after
the move.
If more than one piece of the same type can reach the destination square
then the starting square is also given after the piece designation to
avoid confusion.
A 'Swallow' moving from 5c to 5b and promoting to a 'Goose' is therefore
recorded as Sw-5b+.
NOTE: This system is the official notation system of 'The Shogi
Association'.
DISPLAYING LEGAL MOVES
=========================
If the 'Show Move' option is selected from the Moves Menu, clicking the left
mouse button on a piece on the board or 'in hand' during play will show all
the legal moves of that piece:
- All legal moves (including 'drops') to vacant squares are represented
as White Circles,
- Legal captures are shown as Red Circles. "
