Heian Shogi
Heian shōgi (平安将棋 "Heian era chess") is a predecessor of modern shogi (Japanese chess). Some form of chess almost certainly reached Japan by the 9th century, if not earlier, but the earliest surviving Japanese description of the rules dates from the early 12th century (c. 1120, during the Heian period). Unfortunately, this description does not give enough information to actually play the game, but this has not stopped people from attempting to reconstruct this early form of shogi. Rules of the game Piece movements were as in modern shogi, but there was no rook or bishop. The board appears to have been 9×8 or 8×8. The setup is unknown, but can reasonably be assumed to have been the same as in modern shogi (minus the rook and bishop, and minus a gold general in the 8×8 case), although it's possible that the pawns started on the second rank rather than the third. It can safely be assumed that the game was played without drops. This article outlines a fairly complete set ...

Heian Period
The is the last division of classical Japanese history, running from 794 to 1185. It followed the Nara period, beginning when the 50th emperor, Emperor Kanmu, moved the capital of Japan to Heian-kyō (modern Kyoto). means "peace" in Japanese. It is a period in Japanese history when the Chinese influences were in decline and the national culture matured. The Heian period is also considered the peak of the Japanese imperial court and noted for its art, especially poetry and literature. Two types of Japanese script emerged, including katakana, a phonetic script which was abbreviated into hiragana, a cursive alphabet with a unique writing method distinctive to Japan. This gave rise to Japan's famous vernacular literature, with many of its texts written by court women who were not as educated in Chinese compared to their male counterparts. Although the Imperial House of Japan had power on the surface, the real power was in the hands of the Fujiwara clan, a powerful aristocratic f ...

Perpetual Check
In the game of chess, perpetual check is a situation in which one player can a draw by an unending series of checks. This typically arises when the player who is checking cannot deliver checkmate, and failing to continue the series of checks gives the opponent at least a chance to win. A draw by perpetual check is no longer one of the rules of chess; however, such a situation will eventually allow a draw claim by either threefold repetition or the fifty-move rule. Players usually agree to a draw long before that, however. Perpetual check can also occur in other forms of chess, although the rules relating to it might be different. For example, giving perpetual check is not allowed in shogi and xiangqi, where doing so leads to an automatic loss for the giver. Examples In this diagram, Black is ahead a rook, a bishop, and a pawn, which would normally be a decisive advantage. But White, to move, can draw by perpetual check: : 1. Qe8+ Kh7 : 2. Qh5+ Kg8 : 3. Qe8+ etc. The same po ...

Shogi Variants
A shogi variant is a game related to or derived from shogi (Japanese chess). Many shogi variants have been developed over the centuries, ranging from some of the largest chess-type games ever played to some of the smallest. A few of these variants are still regularly played, though none are as popular as shogi itself. The drop rule, often considered the most notable feature of shogi, is absent from most shogi variants, which therefore play more like other forms of chess, with the board becoming less crowded as pieces are exchanged. This is especially true for variants larger than shogi itself − in fact, the largest well-known variant that features the drop rule is the 11×11 game wa shogi. Predecessors of modern shogi Some form of chess had almost certainly reached Japan by the 9th century, if not earlier, but the earliest surviving Japanese description of the rules of chess dates from the early 12th century, during the Heian period. Unfortunately, this description does not ...

Heian Dai Shogi
Heian dai shogi ( ja, 平安大将棋 'Heian (Era) large chess') is an early large board variant of shogi (Japanese chess) as it was played in the Heian period. The same 12th century document which describes the Heian form of shogi also describes this variant. Unfortunately, this description does not give enough information to actually play the game, but this has not stopped people from attempting to reconstruct this early form of shogi. A fairly complete and playable reconstruction is outlined here. Rules of the game Objective The objective of the game is to capture your opponent's king or to capture all the other pieces, leaving a bare king. Unlike standard shogi, pieces may not be dropped back into play after capture. Game equipment Two players, Black and White (or 先手 ''sente'' and 後手 ''gote''), play on a board ruled into a grid of 13 ''ranks'' (rows) by 13 ''files'' (columns) for a total of 169 squares. The squares are undifferentiated by marking or color. ...

Sho Shogi
Shō shōgi (小将棋 'small chess') is a 16th-century form of shogi (Japanese chess), and the immediate predecessor of the modern game. It was played on a 9×9 board with the same setup as in modern shogi, except that an extra piece stood in front of the king: a 'drunk elephant' that promoted into a prince, which is effectively a second king. While 9×9 may not seem 'small', it was smaller than the other shogi variants prevalent at the time, which were the 12×12 chu shogi and 15×15 dai shogi. According to the ''Sho Shōgi Zushiki'', the drunk elephant was eliminated by the Emperor Go-Nara (reigned 1526–1557), and it is assumed that the drop rule was introduced at about the same time, giving rise to shogi as we know it today. Rules of the game Objective The objective of the game is to capture your opponent's king and crown prince (if present) or all other pieces. Game equipment Two players, Black and White (or 先手 ''sente'' and 後手 ''gote''), play on a board ru ...

Japanese Numerals
The Japanese numerals are the number names used in Japanese. In writing, they are the same as the Chinese numerals, and large numbers follow the Chinese style of grouping by 10,000. Two pronunciations are used: the Sino-Japanese (on'yomi) readings of the Chinese characters and the Japanese yamato kotoba (native words, kun'yomi readings). Basic numbering in Japanese There are two ways of writing the numbers in Japanese: in Arabic numerals (1, 2, 3) or in Chinese numerals (, , ). The Arabic numerals are more often used in horizontal writing, and the Chinese numerals are more common in vertical writing. Most numbers have two readings, one derived from Chinese used for cardinal numbers (On reading) and a native Japanese reading (Kun reading) used somewhat less formally for numbers up to 10. In some cases (listed below) the Japanese reading is generally preferred for all uses. Archaic readings are marked with †. * The special reading 〇 ''maru'' (which means "round" or "circle ...

Algebraic Chess Notation
Algebraic notation (or AN) is the standard method for recording and describing the moves in a game of chess. It is based on a system of coordinates to uniquely identify each square on the chessboard. It is used by most books, magazines, and newspapers. In English-speaking countries, the parallel method of descriptive notation was generally used in chess publications until about 1980. A few players still use descriptive notation, but it is no longer recognized by FIDE, the international chess governing body. Algebraic notation exists in various forms and languages and is based on a system developed by Philipp Stamma. Stamma used the modern names of the squares, but he used p for pawn moves and the original of a piece (a through h) instead of the initial letter of the piece name. The term "algebraic notation" may be considered a misnomer, as the system is unrelated to algebra. Other terms such as "standard notation" and "coordinate notation" have been proposed, but the traditional ...

Checkmate
Checkmate (often shortened to mate) is any game position in chess and other chess-like games in which a player's king is in check (threatened with ) and there is no possible escape. Checkmating the opponent wins the game. In chess, the king is never actually captured—the player loses as soon as the player's king is checkmated. In formal games, it is usually considered good etiquette to resign an inevitably lost game before being checkmated. If a player is not in check but has no legal move, then it is '' stalemate'', and the game immediately ends in a draw. A checkmating move is recorded in algebraic notation using the hash symbol "#", for example: 34.Qg3#. Examples A checkmate may occur in as few as two moves on one side with all of the pieces still on the board (as in Fool's mate, in the opening phase of the game), in a middlegame position (as in the 1956 game called the Game of the Century between Donald Byrne and Bobby Fischer), or after many moves with as few as t ...

Shogi
, also known as Japanese chess, is a strategy board game for two players. It is one of the most popular board games in Japan and is in the same family of games as Western chess, ''chaturanga, Xiangqi'', Indian chess, and '' janggi''. ''Shōgi'' means general's (''shō'' ) board game (''gi'' ). Western chess is sometimes called (''Seiyō Shōgi'' ) in Japan. Shogi was the earliest chess-related historical game to allow captured pieces to be returned to the board by the capturing player. This drop rule is speculated to have been invented in the 15th century and possibly connected to the practice of 15th century mercenaries switching loyalties when captured instead of being killed. The earliest predecessor of the game, chaturanga, originated in India in the sixth century, and the game was likely transmitted to Japan via China or Korea sometime after the Nara period."Shogi". ''Encyclopædia Britannica''. 2002. Shogi in its present form was played as early as the 16th century, while ...

Fairy Chess Piece
A fairy chess piece, variant chess piece, unorthodox chess piece, or heterodox chess piece is a chess piece not used in conventional chess but incorporated into certain chess variants and some chess problems. Compared to conventional pieces, fairy pieces vary mostly in the way they move, but they may also follow special rules for capturing, promotions, etc. Because of the distributed and uncoordinated nature of unorthodox chess development, the same piece can have different names, and different pieces can have the same name in various contexts. Most are symbolised as inverted or rotated icons of the standard pieces in diagrams, and the meanings of these "wildcards" must be defined in each context separately. Pieces invented for use in chess variants rather than problems sometimes instead have special icons designed for them, but with some exceptions (the princess, empress, and occasionally amazon), many of these are not used beyond the individual games for which they were invented ...

Bay Laurel
''Laurus nobilis'' is an aromatic evergreen tree or large shrub with green, glabrous (smooth) leaves. It is in the flowering plant family Lauraceae. It is native to the Mediterranean region and is used as bay leaf for seasoning in cooking. Its common names include bay tree (esp. United Kingdom), bay laurel, sweet bay, true laurel, Grecian laurel, or simply laurel. ''Laurus nobilis'' figures prominently in classical Greco-Roman culture. Worldwide, many other kinds of plants in diverse families are also called "bay" or "laurel", generally due to similarity of foliage or aroma to ''Laurus nobilis''. Description The laurel is an evergreen shrub or small tree, variable in size and sometimes reaching tall. The genus ''Laurus'' includes four accepted species, whose diagnostic key characters often overlap. The bay laurel is dioecious (unisexual), with male and female flowers on separate plants. Each flower is pale yellow-green, about diameter, and they are borne in pairs besid ...
