Recognized Variant of the Month for February 2002. Twelve times per year we will select a
Recognized Variant for special consideration. Its web page will be reworked and improved and a connecting link displayed on all of our CV Pages. We hope to encourage CVPhiles to read about, play and explore this featured variant.
The world's first chess variant
Chaturanga
arose in India in approximately the seventh century AD. From there it migrated both westward and northward, mutating along the way. The western branch became
Shatranj
in Arabia and
Orthodox Chess
in Europe. The northern branch became
Xiangqi
in China and
Changgi in Korea.
Sometime in the 10th to 12th centuries, 'chess' crossed the channel to Japan where it spawned a number of interesting variants. One of these was called 'Small Shogi'. Eventually, Small Shogi (though it went through many forms) won out over the larger variants and is now referred to simply as 'Shogi'. It is certain that Shogi in its present form was played in Japan as early as the 16th century.
(shô ) (-gi)
Shô means general and Gi means board game.
Shogi (rhymes with yogi) means general's game.
Perhaps the enduring popularity of Shogi can be attributed to its 'drop rule'; it was the first chess variant wherein captured pieces could be returned to the board to be used as one's own.
David Pritchard
credits this to the practice of 16th century mercenaries who switched loyalties when captured -- no doubt as an alternative to execution.
Setup
Shogi is played on a 9x9 uncheckered board. Each player begins with one King, one Rook, one Bishop, two Gold Generals, two Silver Generals, two Knights, two Lances and nine Pawns. Four black dots are shown to the board to delineate
promotion zones
(those squares lying on the last three ranks). Unlike
Orthodox Chess,
all Shogi pieces are exactly the same color.
Loyalties are determined by their directional headings. (See below.)
Shogi counters are flat irregular pentagons made of wood or plastic. A kanji symbol is printed on the top of each counter, denoting its identity as a
starting piece.
A second kanji symbol (traditionally red) is printed on the bottom of each counter (King and Gold Generals excepted), denoting its identity as a
promoted piece.
Either the top or bottom may be turned up, during the course of play, in order to display the required symbol .
Starting pieces
The
King (actually 'jeweled general') moves as an Orthodox King.
The
Gold General may move one square vertically, horizontally, or diagonally forward. (In all directions except diagonally rearward).
The
Silver General
may move one square diagonally, or straight forward. (In all directions except horizontally or straight rearward.)
The
Knight
(actually 'honorable horse') has the two forward-most moves of the
Orthodox Knight. For example, a white Knight on d5 may go to c7 or to e7. It may leap over occupied squares.
The
Lance
has the forward-most move of the Orthodox Rook, keeping always in the same file.
(Without promotion the Lance cannot leave its home file.)
The Pawn
(actually 'soldier') moves one square straight forward. Shogi Pawns capture in the same manner as they move -- as do all Shogi pieces.
Promoted pieces
The Silver General promotes to a Gold General. (Here the symbol indicates a promoted Silver General.)
The Knight
promotes to a Gold General. (Here the symbol indicates a promoted Knight.)
The Lance
promotes to a Gold General. (Here the symbol indicates a promoted Lance.)
The Pawn
promotes to a Gold General. (Here the symbol indicates a promoted Pawn.)
The Rook promotes to
Dragon King.
(Here the symbol indicates a promoted Rook -- a Dragon King -- which has the combined moves of King and Rook.)
The Bishop
promotes to
Dragon Horse.
(Here the symbol indicates a promoted Bishop -- a Dragon Horse -- which has the combined moves of King and Bishop.)
NOTE: The King and Gold General do not promote
Rules
A Pawn is tossed to decide which player moves first.
The object of the game is to checkmate the enemy King.
Perpetual check is forbidden. The player initiating the check must break it off.
Promotions are granted as follows...
A
starting piece
moving to a square in the
promotion zone
(the last 3 ranks) earns a promotion. A promotion is indicated by flipping the piece over to display the symbol on its bottom side.
An earned promotion (see above) may be deferred to a later move, as long as this move begins inside the promotion zone (the last 3 ranks). Where the move ends is of no relevance.
Pieces arriving at a rank whereon they can move no further must promote. [e.g., a Pawn or Lance arriving on the 9th rank; a Knight arriving on the 8th or 9th rank.]
Promoted pieces lose their promotion upon capture.
Pieces 'dropped' into the promotion zone (the last 3 ranks) may not promote until making at least one move. (See below).
A captured piece may be dropped onto the board (placed on a vacant square) to subsequently be used as one's own. This is done in lieu of a regular move.
A Pawn may not be dropped onto a
file
containing a non-promoted Pawn.
No piece may be dropped to a square from which it is impossible to move. [e.g., a Pawn or Lance to the 9th
rank;
a Knight to the 8th or 9th rank.]
A checkmate may not be performed by the drop of a Pawn. A King may be checked by dropping a Pawn, but only if the drop does not result in an immediate checkmate.

Thanks for the replies David and Elijah. If you want a game of taikyoku
shogi, you can find it in here.

I think the closest thing to that would be Taiykoku Shogi, with a 36x36 Board and 100+ types of pieces. There's probaly someone around here who's finished a game of the flash version.
Shogi, is of course, an excellent game. But here is what is interesting: In
relation to another CV comment, seemingly unrelated (i.e., Fergus's
comment to research a certain player to see he (Fergus) had no
double-identity).. Well, I did research that player and found out he was
in Tokyo and had a Shogi link which was quite interesting. He also
mentioned a site where you could play Shogi in real-time. So, I went to
http://www.kurnik.org and in minutes won my first 10 minute on-line speed
Shogi game... quite fun. I was then crushing my opponent in a second game
when a most terrible thing happened. I went to move the Rook, but then
realized I could drop a pawn instead and win a Lance for the pawn. When I
clicked to drop the pawn, my Rook moved to that square instead... so,
instead of winning a Lance, I lost a Rook... oh what sorrow due to a
mechanical issue. Anyway, it is fun to play real-time Shogi... and thanks
to the rating system double-idntity issue, a real-time Shogi site was
found.
has some pictures of a (25x25) board and pieces for Tai Shogi. Dane, I think that is about the largest game anyone here will ever play.

Good
How about creating a shogi variant using all the shogi pieces from every game and every piece on the Chess variant pages?! It will probably be about 40 by 40 to 45 by 45 spaces big! Please use all versions of a piece. Please give me credit for the idea . By Dane Rogers. Age 11 and 3/4
