The Japanese Heroes' Game
The Japanese Shogi Chess Game and Its Closest `Relatives'
Moscow: Universitetskaja Kniga.
A brief description (with some mistakes) of Chu Shogi.
Brief mention of the existence of some other variants of the games, such as Maka-Dai-Dai Sh˘gi and three-handed Xiangqi; also of Hasami Sh˘gi, Tobi Sh˘gi (with overtake capture, as in draughts) and Gunjin Sh˘gi (with incomplete information: in the initial setup all pieces are turned upside down, and every one's reverse side is blank, so a player doesn't know how his opponent's army is allocated).
Concise information on some old Chinese CV which is called _Semedo_ (if that was ever a Chinese word, it's been distorted very strongly) in Thomas Hyde's book _Mandragorias, seu Historia shahiludii_, Oxford, 1694. Board is 5 (files) by 8 (ranks); play is on the squares, not on the intersections. Setup: 1 general (c1), 2 mandarins (b1, d1), 2 horses (a1, e1), 2 rockets (cannons? a2, e2), 5 pawns (a3, b-d2, e3); mutatis mutandis ditto for the other player.
A note on the fact that a large Xiangqi version has been invented recently (PRC patent 91301156.8, _Bulletin of Industrial Samples of the PRC_ 11.12. 1991). Board is 13 (ranks) by 14 (files), each player starts the game with 26 pieces, incl. such as are not in Xiangqi.
Also a note on the existence of a game called Large Korean Chess, on a 14 by 15 board. The author says that game bore some similarity to Dai Sh˘gi, but he doesn't say whether it extended to more than the size of the board.
A description of a game of the author's own invention, called Crown, and a more complex version thereof, called Crown-2. Those are very close to Orthochess, but involve incomplete information: some things about your army are not known to your opponent, and he must deduce them by observing the behaviour of your pieces.
