2. About the game of shogi

+ +

- - +

+"Japanese chess cedes nothing in depth or beauty to the European +game... it is at least as interesting."

-Each player at the beginning of a shogi game has a total of 20 pieces of -eight different types. The moves of the shogi pieces can be divided -into three classes: "stepping" pieces, that only move one square at a -time; "ranging" pieces that move any number of unobstructed squares in -a line, and "jumping" pieces that can jump over obstructing pieces to -reach their destination squares. Most pieces can also promote to -different (usually stronger) pieces under certain circumstances (see the -next section). All pieces capture the same way that they move (even -pawns). The piece moves and promotions are as follows; each piece name -is followed by the standard piece abbreviation: - +--- Alexander Alekhine
+(quoted in David Pritchard, The Encyclopedia of Chess Variants) +

  1. +"... shogi [is] by far the most complex form of chess that has ever +achieved widespread popularity." +

    -The king (K). The king can move one square in any horizontal, vertical, -or diagonal direction, just like the king in international chess. The -king does not promote. - -

  2. +--- R. Wayne Schmittberger, New Rules for Classic Games +
+

-The rook (R). The rook can move any number of squares in a horizontal -or vertical direction. The rook is the same as the rook in -international chess (except that it can promote). A rook promotes to a -"dragon king" or "dragon" for short (often just referred to as a -"promoted rook"), which can move as a rook or can move one square in -any diagonal direction. +Shogi is the version of chess played in Japan. It is strikingly +different from standard chess (which I shall refer to henceforth as +"international chess") and also to all other regional variants, +because captured pieces can re-enter play on the side of the capturer. +This has several interesting effects on the play of the game: +

+

  1. - -The bishop (B). The bishop can move any number of squares in a diagonal -direction. The bishop is the same as the bishop in international chess -(except that it can promote). A bishop promotes to a "dragon horse" -or "horse" for short (often just referred to as a "promoted -bishop"), which can move as a bishop or can move one square in any -horizontal or vertical direction. Note: the horse should not be -confused with a knight (see below), as they are two completely different -pieces. +Shogi is much more complex than international chess, at least in +terms of the average number of possible moves per turn (estimated at +about 35 for chess and at about 80 for shogi). +

  2. - -The gold general (G). A gold general can move one square in any -horizontal or vertical direction, or one square in a forward diagonal -direction. Gold generals do not promote. +There are almost no draws (about 1-2% of all games in professional play). +

  3. - -The silver general (S). A silver general can move one square in any -diagonal direction, or one square straight forward. A silver general -promotes to a gold general. +Exchanges complicate the play rather than simplifying it. +

  4. - -The knight (N). A knight can move one square straight forward followed -by one square to either forward diagonal, jumping over intervening -pieces if any. In other words, a knight moves like its international -chess counterpart, but forward only. A knight promotes to a gold -general. The knight is the only jumping piece, as in chess. +There are no "endgames" in the standard chess sense; all pieces remain +in play throughout the game. Games typically end in a race to +checkmate the other player before being checkmated oneself. +

  5. - -The lance (L). A lance can move any number of squares straight forward. -A lance promotes to a gold general. +Ownership of a piece is not indicated by the color of the piece; +instead, pieces are wedge-shaped and point towards the opponent. The +name of the piece is inscribed in Kanji characters on the front of the +piece. +

  6. - -The pawn (P). A pawn can move one square straight forward. The pawn -captures the same way that it moves, in contrast to international chess. -There is also no initial two-space move for pawns and no -en-passant capture. A pawn promotes to a gold general; a -promoted pawn is usually known as a "Tokin". +Most importantly: it's more fun than other forms of chess :-) +

+

+ +Shogi is extremely popular in Japan; it has been estimated that 20 +million Japanese can play shogi, of which perhaps 1 million are active +players. It is even more popular there than the game of go, Japan's +other favorite board game. There are a number of professional players +who make a considerable amount of money playing in shogi tournaments, +and the game receives extensive newpaper and television coverage. +Despite this, the game has yet to become popular outside of Japan. Part +of this is because the Kanji characters on the pieces scare away some +people, but mostly it's due, I think, to lack of exposure to the game +and to the difficulty of finding opponents. I hope that GNU shogi will +help introduce shogi to a wider audience. +
