I recently discovered a Japanese chess variation, called
"Shogi", which I believe some of you might find interesting.
What follows here is a description of the game.
The major differences between 'our' chess and Shogi are as
follows:
1) Shogi is played on a 9x9 board
2) Pieces have slightly different capabilities.
3) All pieces, with the exception of the 'king' and a
'gold' (explanation to follow) are allowed to promote.
Promotion is fixed (that is, each piece turns into
another certain kind of piece. Under-promotion is
not allowed).
4) Promotion occurs when pieces reach the 7th, 8th, or 9th
rows, not just the last.
5) A player, in his turn, has the option of moving a piece
or, if he has captured any of the opponent's pieces, can
'warp in' one of these captured pieces AS HIS OWN, on
any unoccupied square. If placed in the 7th, 8th, or
9th rows the piece does not promote until it is moved
once, and then only if it is not moved to the first
six rows.
The initial board configuration is as follows:
L N S G K G S N L
. R . . . . . B .
P P P P P P P P P
. . . . . . . . .
. . . . . . . . .
. . . . . . . . .
p p p p p p p p p
. b . . . . . r .
l n s g k g s n l
where:
L is a 'lance'. Lances move straight forward only, any number of
squares. They promote to 'Golds'.
N is a knight. Knights move as do traditional knights, and as with
traditional knights they are allowed to 'jump over' other pieces.
No other piece has this capability. Lances promote to Golds.
S is a 'silver'. Silvers have no counterpart in traditional chess,
and move as follows: they can move one square to the three squares
in front of them, or to the two rear diagonals but NOT directly
back, to the left, or to the right. As follows:
X X X
. S .
X . X
where the X's indicate possible moves. Silvers promote to
golds.
G is a 'gold'. Using the notation above, golds have the possible
moves
X X X
X G X
. X .
Golds do not promote: that is, they remain golds. Golds
and silvers can be thought of as have slightly restricted
variations of a king's movement.
K is a king, and moves as does a normal king.
R is a rook, and moves as does a normal rook. Upon promotion,
it turns into a 'super-rook': it is still able to move as
does a rook, but if required, it can instead move to any
adjacent square. (Think of a super-rook's movement as being
that of a rook or that of a king.)
B is a bishop, and moves as does a normal bishop. Upon promotion,
it turns into a 'super-bishop': it is still able to move as
does a bishop, but if required, it can instead move to any
adjacent square. (Once again, it has either a king's movement
or an ordinary bishop's).
P is a pawn. Pawns move one square at a time, directly forward
only. They do not capture to the diagonals, and are not
allows the 'en-passant' moves or the initial double-jump.
All pieces capture on squares they can move to.
The physical implementation of the board requires that all
pieces be the same color since an opponent's piece can become
your own, and vice versa. Instead of color-differentiation,
Shogi uses orientation-differentiation. Pieces are yours
if they 'point' towards the opponent, and the opponent's if
they 'point' towards you. They generally have the following
shape:
-----
/ --- \
/ ----- \
/ ------- \
/ --------- \
-------------
Furthermore, they are flat, such that they can be turned over
when promoted. (Each side has a character indicating the piece's
value; note that although most pieces promote to golds, the promotion-
side character on a lance is different from that on the promotion-side
of a silver, even though they both become golds. This is because
Captured pieces, when warped back onto the board, revert to their
original status even though they may have been promoted while under
the opponent's control. One needs a way to differentiate between
promoted knights, silvers, pawns, etc. since this has a serious effect
one one's strategy.)
That's it! If anyone is interested either in play-by-email, or
in person if you live in New Jersey near Holmdel/Eatontown/Rumson,
please contact me. I will also answer any questions you may
have about the game.

I.e. you can't have a pawn or lance on the ninth rank, or a knight on 8th or 9th rank. If you have an unpromoted pawn on the 8th rank and move it to the 9th, you must promote it. * You cannot "warp in" a pawn on a column that already has an unpromoted pawn that you own. * You cannot mate by "warping in" a pawn (other pieces are OK). * Knights move only forward. * Pawns promote to "gold". Why would you ever want a piece that can't move? Well, if your king is on the 9th rank and is under check from a rook or a bishop, and you have a pawn or a knight, you might want to "warp in" a pawn on the 9th rank or knight on 8th rank to get out of check....but you can't do it.

> I think Mr. Ramming has left out a few rules. ... > Takashi Iwasawa Entirely possible. The game as I learned it was passed verbally through a chain of 3 people over a span of 8 years. These new rules make sense; thanks for pointing out the errors in my version. Do you also happen to know what the various pieces are actually called in Japanese? J.

There are sample games of most versions. This book is a reprint of a much earlier work (around 1900?) so the language may seem dated but there is enough detail on each of the games to be able to learn the moves. I was able to obtain chess sets for both shogi and chinese chess in San Francisco in 1978, the chinese set in a shop in chinatown (where else?), and the shogi set at a shop in the "Oriental Trade Center"(or something like that).

Beware! It is an old book and the research is faulty. While the games described in the book are interesting games, I recall for certain that the rules provided for Chinese chess are incorrect, and that makes me suspicious of most of the other games as well. As for Shogi, there is/was a book on the game which included die-cut cardboard pieces with both the Japanese glyph and a western symbol to simplify learning. As usual, my information is at home, and I'm not, so I can't be more specific, nor do I know if this book is still in print. -- Mike Urban ...!trwrb!trwspp!spp2!urban "You're in a maze of twisty UUCP connections, all alike"

It's "SHOGI - Japan's Game of Strategy", by Trevor Leggett. I'll give complete info, since it may not be easily available in the U.S. Published by Charles E. Tuttle Company of Rutland, VT and Tokyo, Japan. (c) 1966 by Charles E. Tuttle Co., Inc. First edition, 1966. Fifth printing (my copy) 1976.

If you have Japanese-American bookstores in your area, such as Kinokuniya in L.A. and S.F., you might try those, but no guarantees. Besides the die-cut pieces Mike mentioned, it has a fold-out board and an appendix on how to read Japanese games scores, so that you can play through the games in your favorite newspaper. -- Jim Gillogly {decvax, vortex}!randvax!jim jim@rand-unix.arpa

This book is by Trevor Leggatt and is usable although I found the icons objectionable. The Shogi Association Ltd., P.O. Box 77, Bromley, Kent, ENGLAND. was publishing a magazine and preparing an introductory book when I left England in 1978. It had also produced a well researched book of the Great Shogi Games. Shogi rules were fixed around 1600. Prior to then there were commonly played variants for 12x12 15x15 17x17 19x19 and 25x25. These was another set of shogi games played on oblong boards. The book describes the rules for the square boards and The Shogi Association had had sets made with which to play the games. As for Shogi, I can provide a program which knows the rules. It solves mating puzzles, slowly and at great expense of memory, but the move verification code could be reused. -- -- {ihnp4|vax135|allegra}!lznv!nrh Nigel The Mad Englishman or The Madly Maundering Mumbler in the Wildernesses Everything you have read here is a figment of your imagination.
