The Korea Baduk Association , also known as Hanguk Kiwon ( Korean : 한국기원 ), was founded in November 1945 by Cho Namchul .
110-619: Baduk is a game which was present in Korea by the 5th century. It originated in China, but the West is more familiar with the Japanese name Go . This is because the Japanese were the first to introduce it to the West. Japan was introduced to the game in the 7th century AD. Initially, most Korean players followed the sunjang style of beginning by placing sixteen stones —eight white and eight black— on
220-410: A ko threat . Because Black has the advantage of playing the first move, the idea of awarding White some compensation came into being during the 20th century. This is called komi , which gives white a 5.5-point compensation under Japanese rules, 6.5-point under Korean rules, and 15/4 stones, or 7.5-point under Chinese rules (number of points varies by rule set). Under handicap play, White receives only
330-495: A phonemic split of their tone categories. Syllables with voiced initials tended to be pronounced with a lower pitch, and by the late Tang dynasty , each of the tones had split into two registers conditioned by the initials, known as the "upper" and "lower". When voicing was lost in most varieties (except in the Wu and Old Xiang groups and some Gan dialects), this distinction became phonemic, yielding up to eight tonal categories, with
440-414: A 0.5-point komi, to break a possible tie ( jigo ). Two general types of scoring procedures are used, and players determine which to use before play. Both procedures almost always give the same winner. Both procedures are counted after both players have passed consecutively, the stones that are still on the board but unable to avoid capture, called dead stones, are removed. Given that the number of stones
550-557: A Late Middle Chinese koiné and cannot very easily be used to determine the pronunciation of Early Middle Chinese. During the Early Middle Chinese period, large amounts of Chinese vocabulary were systematically borrowed by Vietnamese, Korean and Japanese (collectively the Sino-Xenic pronunciations ), but many distinctions were inevitably lost in mapping Chinese phonology onto foreign phonological systems. For example,
660-512: A better understanding and analysis of Classical Chinese poetry , such as the study of Tang poetry . The reconstruction of Middle Chinese phonology is largely dependent upon detailed descriptions in a few original sources. The most important of these is the Qieyun rime dictionary (601) and its revisions. The Qieyun is often used together with interpretations in Song dynasty rime tables such as
770-447: A black stone. Such a point is often called a false eye . There is an exception to the requirement that a group must have two eyes to be alive, a situation called seki (or mutual life ). Where different colored groups are adjacent and share liberties, the situation may reach a position when neither player wants to move first because doing so would allow the opponent to capture; in such situations therefore both players' stones remain on
880-404: A circled point, because doing so would allow the opponent to capture their group on the next move. The outer groups in this example, both black and white, are alive. Seki can result from an attempt by one player to invade and kill a nearly settled group of the other player. Tactics deal with immediate fighting between stones, capturing and saving stones, life, death and other issues localized to
990-482: A close analysis of regularities in the system and co-occurrence relationships between the initials and finals indicated by the fanqie characters. However, the analysis inevitably shows some influence from LMC, which needs to be taken into account when interpreting difficult aspects of the system. The Yunjing is organized into 43 tables, each covering several Qieyun rhyme classes, and classified as: Each table has 23 columns, one for each initial consonant. Although
1100-516: A compact presentation. Each square in a table contains a character corresponding to a particular homophone class in the Qieyun , if any such character exists. From this arrangement, each homophone class can be placed in the above categories. The rime dictionaries and rime tables identify categories of phonetic distinctions but do not indicate the actual pronunciations of these categories. The varied pronunciations of words in modern varieties of Chinese can help, but most modern varieties descend from
1210-562: A detrimental "craze". Older versions of the rime dictionaries and rime tables came to light over the first half of the 20th century, and were used by such linguists as Wang Li , Dong Tonghe and Li Rong in their own reconstructions. Edwin Pulleyblank argued that the systems of the Qieyun and the rime tables should be reconstructed as two separate (but related) systems, which he called Early and Late Middle Chinese, respectively. He further argued that his Late Middle Chinese reflected

Players usually start near the corners because establishing territory is easier with the aid of two edges of the board. Established corner opening sequences are called joseki and are often studied independently. However, in the mid-game, stone groups must also reach in towards the large central area of
1430-490: A handicap—Black is allowed to place two or more stones on the board to compensate for White's greater strength. There are different rulesets (Korean, Japanese, Chinese, AGA, etc.), which are almost entirely equivalent, except for certain special-case positions and the method of scoring at the end. Basic strategic aspects include the following: The strategy involved can become very abstract and complex. High-level players spend years improving their understanding of strategy, and
1540-422: A hierarchy of tone, rhyme and homophony. Characters with identical pronunciations are grouped into homophone classes, whose pronunciation is described using two fanqie characters, the first of which has the initial sound of the characters in the homophone class and second of which has the same sound as the rest of the syllable (the final). The use of fanqie was an important innovation of the Qieyun and allowed
1650-428: A large number of consonants and vowels, many of them very unevenly distributed. Accepting Karlgren's reconstruction as a description of medieval speech, Chao Yuen Ren and Samuel E. Martin analysed its contrasts to extract a phonemic description. Hugh M. Stimson used a simplified version of Martin's system as an approximate indication of the pronunciation of Tang poetry. Karlgren himself viewed phonemic analysis as
1760-690: A larger board with more scope for play and longer games and, on average, many more alternatives to consider per move. The number of legal board positions in Go has been calculated to be approximately 2.1 × 10 , which is far greater than the number of atoms in the observable universe , which is estimated to be on the order of 10 . The name Go is a short form of the Japanese word igo ( 囲碁 ; いご ), which derives from earlier wigo ( ゐご ), in turn from Middle Chinese ɦʉi gi ( 圍棋 , Mandarin : wéiqí , lit. ' encirclement board game ' or ' board game of surrounding ' ). In English,
1870-474: A more sophisticated and convenient analysis of the Qieyun phonology. The rime tables attest to a number of sound changes that had occurred over the centuries following the publication of the Qieyun . Linguists sometimes refer to the system of the Qieyun as Early Middle Chinese and the variant revealed by the rime tables as Late Middle Chinese . The dictionaries and tables describe pronunciations in relative terms, but do not give their actual sounds. Karlgren
1980-490: A move is not suicide because the Black stones are removed first. In the "Examples of eyes" diagram, all the circled points are eyes. The two black groups in the upper corners are alive, as both have at least two eyes. The groups in the lower corners are dead, as both have only one eye. The group in the lower left may seem to have two eyes, but the surrounded empty point marked a is not actually an eye. White can play there and take
2090-416: A novice may play many hundreds of games against opponents before being able to win regularly. Strategy deals with global influence, the interaction between distant stones, keeping the whole board in mind during local fights, and other issues that involve the overall game. It is therefore possible to allow a tactical loss when it confers a strategic advantage. Novices often start by randomly placing stones on
2200-432: A player has on the board is directly related to the number of prisoners their opponent has taken, the resulting net score, that is, the difference between Black's and White's scores is identical under both rulesets (unless the players have passed different numbers of times during the course of the game). Thus, the net result given by the two scoring systems rarely differs by more than a point. While not actually mentioned in

Baxter produced his own notation for

#17327919262342420-436: A process now known as tonogenesis . Haudricourt further proposed that tone in the other languages, including Middle Chinese, had a similar origin. Other scholars have since uncovered transcriptional and other evidence for these consonants in early forms of Chinese, and many linguists now believe that Old Chinese was atonal. Around the end of the first millennium AD, Middle Chinese and the southeast Asian languages experienced
2530-454: A situation in which the ko rule applies Players are not allowed to make a move that returns the game to the immediately prior position. This rule, called the ko rule , prevents unending repetition (a stalemate). As shown in the example pictured: White had a stone where the red circle was, and Black has just captured it by playing a stone at 1 (so the White stone has been removed). However, it
2640-480: A six-way contrast in unchecked syllables and a two-way contrast in checked syllables. Cantonese maintains these tones and has developed an additional distinction in checked syllables, resulting in a total of nine tonal categories. However, most varieties have fewer tonal distinctions. For example, in Mandarin dialects the lower rising category merged with the departing category to form the modern falling tone, leaving
2750-416: A slightly different set of initials from the traditional set. Moreover, most scholars believe that some distinctions among the 36 initials were no longer current at the time of the rime tables, but were retained under the influence of the earlier dictionaries. Early Middle Chinese (EMC) had three types of stops: voiced, voiceless, and voiceless aspirated. There were five series of coronal obstruents , with
2860-491: A specific part of the board. Larger issues which encompass the territory of the entire board and planning stone-group connections are referred to as Strategy and are covered in the Strategy section above. There are several tactical constructs aimed at capturing stones. These are among the first things a player learns after understanding the rules. Recognizing the possibility that stones can be captured using these techniques
2970-400: A stone can never be moved and can be taken off the board only if it is captured . A player may pass their turn, declining to place a stone, though this is usually only done at the end of the game when both players believe nothing more can be accomplished with further play. When both players pass consecutively, the game ends and is then scored . Vertically and horizontally adjacent stones of
3080-403: A stone such that it or its group immediately has no liberties unless doing so immediately deprives an enemy group of its final liberty. In the second case, the enemy group is captured, leaving the new stone with at least one liberty, so the new stone can be placed. This rule is responsible for the all-important difference between one and two eyes: if a group with only one eye is fully surrounded on
3190-414: A three-way distinction between dental (or alveolar ), retroflex and palatal among fricatives and affricates , and a two-way dental/retroflex distinction among stop consonants . The following table shows the initials of Early Middle Chinese, with their traditional names and approximate values: Old Chinese had a simpler system with no palatal or retroflex consonants; the more complex system of EMC

Black plays first unless given a handicap of two or more stones, in which case White plays first. The players may choose any unoccupied intersection to play on except for those forbidden by the ko and suicide rules (see below). Once played,
3410-426: A vowel, an optional final consonant and a tone. Their reconstruction is much more difficult than the initials due to the combination of multiple phonemes into a single class. The generally accepted final consonants are semivowels /j/ and /w/ , nasals /m/ , /n/ and /ŋ/ , and stops /p/ , /t/ and /k/ . Some authors also propose codas /wŋ/ and /wk/ , based on the separate treatment of certain rhyme classes in

3520-666: A way as to construct territories rather than kill. The end of the middlegame and transition to the endgame is marked by a few features. Near the end of a game, play becomes divided into localized fights that do not affect each other, with the exception of ko fights, where before the central area of the board related to all parts of it. No large weak groups are still in serious danger. Moves can reasonably be attributed some definite value, such as 20 points or fewer, rather than simply being necessary to compete. Both players set limited objectives in their plans, in making or destroying territory, capturing or saving stones. These changing aspects of

Stones in a chain share their liberties. A chain of stones must have at least one liberty to remain on the board. When a chain is surrounded by opposing stones so that it has no liberties, it is captured and removed from the board. An example of

Middle Chinese Middle Chinese (formerly known as Ancient Chinese ) or the Qieyun system (QYS) is the historical variety of Chinese recorded in the Qieyun , a rime dictionary first published in 601 and followed by several revised and expanded editions. The Swedish linguist Bernhard Karlgren believed that the dictionary recorded a speech standard of

The significance of the 4 rows within each tone is difficult to interpret, and
4070-421: Is readily apparent that now Black's stone at 1 is immediately threatened by the three surrounding White stones. If White were allowed to play again on the red circle, it would return the situation to the original one, but the ko rule forbids that kind of endless repetition. Thus, White is forced to move elsewhere, or pass. If White wants to recapture Black's stone at 1 , White must attack Black somewhere else on
4180-420: Is strongly debated. These rows are usually denoted I, II, III and IV, and are thought to relate to differences in palatalization or retroflexion of the syllable's initial or medial, or differences in the quality of similar main vowels (e.g. /ɑ/ , /a/ , /ɛ/ ). Other scholars do not view them not as phonetic categories, but instead as formal devices exploiting distributional patterns in the Qieyun to achieve

A formation having two or more eyes is said to be unconditionally alive , so it can evade capture indefinitely, and a group that cannot form two eyes is said to be dead and can be captured. The general strategy is to place stones to fence-off territory, attack

All reconstructions of Middle Chinese since Karlgren have followed his approach of beginning with the categories extracted from the rime dictionaries and tables, and using dialect and Sino-Xenic data (and in some cases transcription data) in a subsidiary role to fill in sound values for these categories. Jerry Norman and W. South Coblin have criticized this approach, arguing that viewing

The most widely used transcriptions are Li Fang-Kuei's modification of Karlgren's reconstruction and William Baxter's typeable notation . The preface of
4950-431: The Qieyun system is no longer viewed as describing a single form of speech, linguists argue that this enhances its value in reconstructing earlier forms of Chinese, just as a cross-dialectal description of English pronunciations contains more information about earlier forms of English than any single modern form. The emphasis has shifted from precise phones to the structure of the phonological system. Li Fang-Kuei , as

Although

However, significant sections of a version of the Qieyun itself were subsequently discovered in the caves of Dunhuang , and a complete copy of Wang Renxu's 706 edition from the Palace Library was found in 1947. The rhyme dictionaries organize Chinese characters by their pronunciation, according to

This does not lead to cases where two homophone classes are conflated, as the grades (rows) are arranged so that all would-be minimal pairs distinguished only by the retroflex vs. palatal vs. alveolar character of the initial end up in different rows. Each initial

An earlier version comprising 30 initials is known from fragments among the Dunhuang manuscripts . In contrast, identifying the initials of the Qieyun required a painstaking analysis of fanqie relationships across the whole dictionary, a task first undertaken by the Cantonese scholar Chen Li in 1842 and refined by others since. This analysis revealed
5500-473: The board . Once placed, stones may not be moved, but captured stones are immediately removed from the board. A single stone (or connected group of stones) is captured when surrounded by the opponent's stones on all orthogonally adjacent points. The game proceeds until neither player wishes to make another move. When a game concludes, the winner is determined by counting each player's surrounded territory along with captured stones and komi (points added to

The standard Go board has a 19×19 grid of lines, containing 361 points.

Boards with a 19×19 grid had become standard, however, by

The remaining syllables, ending in stop consonants , were described as the " entering " tone counterparts of syllables ending with the corresponding nasals. The Qieyun and its successors were organized around these categories, with two volumes for the even tone, which had

If a Black group has two eyes, White can never capture it because White cannot remove both liberties simultaneously. If Black has only one eye, White can capture the Black group by playing in the single eye, removing Black's last liberty. Such
6050-405: The Cantonese scholar Chen Li in a careful analysis published in his Qieyun kao (1842). Chen's method was to equate two fanqie initials (or finals) whenever one was used in the fanqie spelling of the pronunciation of the other, and to follow chains of such equivalences to identify groups of spellers for each initial or final. For example, the pronunciation of the character 東 was given using
6160-437: The black group with false eye a can be killed by white in two turns. When a group of stones is mostly surrounded and has no options to connect with friendly stones elsewhere, the status of the group is either alive, dead or unsettled . A group of stones is said to be alive if it cannot be captured, even if the opponent is allowed to move first. Conversely, a group of stones is said to be dead if it cannot avoid capture, even if

If White's forcing move is successful, it is termed "gaining the sente "; if Black responds elsewhere on the board, then White can retake Black's stone at 1 , and the ko continues, but this time Black must move elsewhere. A repetition of such exchanges is called a ko fight . To stop the potential for ko fights , two stones of

The rules do not allow a board position to be repeated. Therefore, any move which would restore

However, based on the preface of the Qieyun , most scholars now believe that it records a compromise between northern and southern reading and poetic traditions from the late Northern and Southern dynasties period. This composite system contains important information for the reconstruction of the preceding system of Old Chinese phonology (early 1st millennium BC). The fanqie method used to indicate pronunciation in these dictionaries, though an improvement on earlier methods, proved awkward in practice. The mid-12th-century Yunjing and other rime tables incorporate
7040-494: The dialect data through the rime dictionaries and rime tables distorts the evidence. They argue for a full application of the comparative method to the modern varieties, supplemented by systematic use of transcription data. The traditional analysis of the Chinese syllable , derived from the fanqie method, is into an initial consonant, or "initial", ( shēngmǔ 聲母 ) and a final ( yùnmǔ 韻母 ). Modern linguists subdivide

Finals with stop codas are distributed in the same way as corresponding nasal finals, and are described as their entering tone counterparts.

In 1954, André-Georges Haudricourt showed that Vietnamese counterparts of the rising and departing tones corresponded to final /ʔ/ and /s/ , respectively, in other (atonal) Austroasiatic languages . He thus argued that the Austroasiatic proto-language had been atonal, and that the development of tones in Vietnamese had been conditioned by these consonants, which had subsequently disappeared,

Each final is contained within a single rhyme class, but a rhyme class may contain between one and four finals. Finals are usually analysed as consisting of an optional medial, either a semivowel , reduced vowel or some combination of these,

In the end game players may pass rather than place a stone if they think there are no further opportunities for profitable play. The game ends when both players pass or when one player resigns. In general, to score the game, each player counts the number of unoccupied points surrounded by their stones and then subtracts the number of stones that were captured by
7590-540: The end of the 19th century, European students of Chinese sought to solve this problem by applying the methods of historical linguistics that had been used in reconstructing Proto-Indo-European . Volpicelli (1896) and Schaank (1897) compared the rime tables at the front of the Kangxi Dictionary with modern pronunciations in several varieties, but had little knowledge of linguistics. Bernhard Karlgren , trained in transcription of Swedish dialects, carried out

The tone system of Middle Chinese is strikingly similar to those of its neighbours in the Mainland Southeast Asia linguistic area — proto-Hmong–Mien , proto-Tai and early Vietnamese —none of which is genetically related to Chinese. Moreover, the earliest strata of loans display a regular correspondence between tonal categories in

Another essential component of the game is control of the sente (that is, controlling the offense, so that one's opponent is forced into defensive moves); this usually changes several times during play. Initially the board is bare, and players alternate turns to place one stone per turn. As

Most reconstructions of Middle Chinese include the glides /j/ and /w/ , as well as a combination /jw/ , but many also include vocalic "glides" such as /i̯/ in a diphthong /i̯e/ . Final consonants /j/ , /w/ , /m/ , /n/ , /ŋ/ , /p/ , /t/ and /k/ are widely accepted, sometimes with additional codas such as /wk/ or /wŋ/ . Rhyming syllables in

8470-549: The game proceeds, players try to link their stones together into "living" formations (meaning that they are permanently safe from capture), as well as threaten to capture their opponent's stones and formations. Stones have both offensive and defensive characteristics, depending on the situation. An essential concept is that a formation of stones must have, or be capable of making, at least two enclosed open points known as eyes to preserve itself from being captured. A formation having at least two eyes cannot be captured, even after it
8580-480: The game usually occur at much the same time, for strong players. In brief, the middlegame switches into the endgame when the concepts of strategy and influence need reassessment in terms of concrete final results on the board. Aside from the order of play (alternating moves, Black moves first or takes a handicap) and scoring rules, there are essentially only two rules in Go: Almost all other information about how
8690-406: The game. In the opening of the game, players usually play and gain territory in the corners of the board first, as the presence of two edges makes it easier for them to surround territory and establish the eyes they need. From a secure position in a corner, it is possible to lay claim to more territory by extending along the side of the board. The opening is the most theoretically difficult part of
8800-417: The joining of Bat , meaning 'field', and Dok , meaning 'stone'. Less plausible etymologies include a derivation of Badukdok , referring to the playing pieces of the game, or a derivation from Chinese páizi ( 排子 ), meaning 'to arrange pieces'. Go is an adversarial game between two players with the objective of capturing territory. That is, occupying and surrounding a larger total empty area of
8910-415: The level tone as mid ( ˧ or 33), the rising tone as mid rising ( ˧˥ or 35), the departing tone as high falling ( ˥˩ or 51), and the entering tone as ˧3ʔ. Some scholars have voiced doubts about the degree to which the names were descriptive, because they are also examples of the tone categories. Some descriptions from contemporaries and other data seem to suggest a somewhat different picture. For example,
9020-475: The life of a large group, while others may be worth just one or two points. Some ko fights are referred to as picnic kos when only one side has a lot to lose. In Japanese, it is called a hanami ko. Playing with others usually requires a knowledge of each player's strength, indicated by the player's rank (increasing from 30 kyu to 1 kyu, then 1 dan to 7 dan, then 1 dan pro to 9 dan pro). A difference in rank may be compensated by
9130-596: The medial (especially when it is /w/ ) or in so-called chongniu doublets. The Yunjing ( c. 1150 AD ) is the oldest of the so-called rime tables , which provide a more detailed phonological analysis of the system contained in the Qieyun . The Yunjing was created centuries after the Qieyun , and the authors of the Yunjing were attempting to interpret a phonological system that differed in significant ways from that of their own Late Middle Chinese (LMC) dialect. They were aware of this, and attempted to reconstruct Qieyun phonology as well as possible through
9240-509: The middlegame, the players invade each other's territories, and attack formations that lack the necessary two eyes for viability. Such groups may be saved or sacrificed for something more significant on the board. It is possible that one player may succeed in capturing a large weak group of the opponent's, which often proves decisive and ends the game by a resignation. However, matters may be more complex yet, with major trade-offs, apparently dead groups reviving, and skillful play to attack in such
9350-481: The most words, and one volume each for the other tones. The pitch contours of modern reflexes of the four Middle Chinese tones vary so widely that linguists have not been able to establish the probable Middle Chinese values by means of the comparative method . Karlgren interpreted the names of the first three tones literally as level, rising and falling pitch contours, respectively, and this interpretation remains widely accepted. Accordingly, Pan and Zhang reconstruct
9460-552: The name Go when used for the game is often capitalized to differentiate it from the common word go . In events sponsored by the Ing Chang-ki Foundation, it is spelled goe . The Korean name baduk (바둑) derives from the Middle Korean word Badok , the origin of which is controversial; the more plausible etymologies include the suffix dok added to Ba to mean 'flat and wide board', or
9570-404: The oldest known description of the tones, which is found in a Song dynasty quotation from the early 9th century Yuanhe Yunpu 元和韻譜 (no longer extant): Level tone is sad and stable. Rising tone is strident and rising. Departing tone is clear and distant. Entering tone is straight and abrupt. In 880, the Japanese monk Annen, citing an account from the early 8th century, stated the level tone
9680-448: The opening, players often play established sequences called joseki , which are locally balanced exchanges; however, the joseki chosen should also produce a satisfactory result on a global scale. It is generally advisable to keep a balance between territory and influence. Which of these gets precedence is often a matter of individual taste. The middle phase of the game is the most combative, and usually lasts for more than 100 moves. During
9790-427: The opponent's weak groups (trying to kill them so they will be removed), and always stay mindful of the life status of one's own groups. The liberties of groups are countable. Situations where mutually opposing groups must capture each other or die are called capturing races, or semeai . In a capturing race, the group with more liberties will ultimately be able to capture the opponent's stones. Capturing races and
9900-481: The opponent. The player with the greater score (after adjusting for handicapping called komi ) wins the game. In the opening stages of the game, players typically establish groups of stones (or bases ) near the corners and around the sides of the board, usually starting on the third or fourth line in from the board edge rather than at the very edge of the board. The edges and corners make it easier to develop groups which have better options for life (self-viability for
10010-569: The other types of data, since the pronunciation of the foreign languages borrowed from—especially Sanskrit and Gandhari —is known in great detail. For example, the nasal initials /m n ŋ/ were used to transcribe Sanskrit nasals in the early Tang, but later they were used for Sanskrit unaspirated voiced initials /b d ɡ/ , suggesting that they had become prenasalized stops [ᵐb] [ⁿd] [ᵑɡ] in some northwestern Chinese dialects. The rime dictionaries and rime tables yield phonological categories, but with little hint of what sounds they represent. At
10120-433: The outside, it can be killed with a stone placed in its single eye. (An eye is an empty point or group of points surrounded by a group of stones). The Ing and New Zealand rules do not have this rule, and there a player might destroy one of its own groups (commit suicide). This play would only be useful in limited sets of situations involving a small interior space or planning. In the example at right, it may be useful as
10230-413: The owner of the group is allowed the first move. Otherwise, the group is said to be unsettled: the defending player can make it alive or the opponent can kill it, depending on who gets to play first. An eye is an empty point or group of points surrounded by a group of stones. If the eye is surrounded by Black stones, White cannot play there unless such a play would take Black's last liberty and capture
10340-573: The present day. A 2016 survey by the International Go Federation 's 75 member nations found that there are over 46 million people worldwide who know how to play Go, and over 20 million current players, the majority of whom live in East Asia . The playing pieces are called stones . One player uses the white stones and the other black. The players take turns placing their stones on the vacant intersections ( points ) on
10450-431: The previous board position would not be allowed, and the next player would be forced to play somewhere else. If the play requires a strategic response by the first player, further changing the board, then the second player could "retake the ko," and the first player would be in the same situation of needing to change the board before trying to take the ko back. And so on. Some of these ko fights may be important and decide
10560-405: The pronunciation of all characters to be described exactly; earlier dictionaries simply described the pronunciation of unfamiliar characters in terms of the most similar-sounding familiar character. The fanqie system uses multiple equivalent characters to represent each particular initial, and likewise for finals. The categories of initials and finals actually represented were first identified by
10670-420: The retroflex dentals are represented with the dentals, while elsewhere they have merged with the retroflex sibilants. In the south these have also merged with the dental sibilants, but the distinction is retained in most Mandarin dialects. The palatal series of modern Mandarin dialects, resulting from a merger of palatal allophones of dental sibilants and velars, is a much more recent development, unconnected with
10780-412: The rules of Go (at least in simpler rule sets, such as those of New Zealand and the U.S.), the concept of a living group of stones is necessary for a practical understanding of the game. Examples of eyes (marked). The black groups at the top of the board are alive, as they have at least two eyes. The black groups at the bottom are dead as they only have one eye. The point marked a is a false eye, thus
10890-410: The same color form a chain (also called a string or group ), forming a discrete unit that cannot then be divided. Only stones connected to one another by the lines on the board create a chain; stones that are diagonally adjacent are not connected. Chains may be expanded by placing additional stones on adjacent intersections, and they can be connected together by placing a stone on an intersection that
11000-451: The same color would need to be added to the group, making either a group of 5 Black or 5 White stones. While the various rulesets agree on the ko rule prohibiting returning the board to an immediately previous position, they deal in different ways with the relatively uncommon situation in which a player might recreate a past position that is further removed. See Rules of Go § Repetition for further information. A player may not place
11110-483: The second or fourth rows for some initials. Most linguists agree that division-III finals contained a /j/ medial and that division-I finals had no such medial, but further details vary between reconstructions. To account for the many rhyme classes distinguished by the Qieyun , Karlgren proposed 16 vowels and 4 medials. Later scholars have proposed numerous variations. The four tones of Middle Chinese were first listed by Shen Yue c. 500 AD . The first three,
11220-568: The speech standard of the capital Chang'an of the Sui and Tang dynasties . He interpreted the many distinctions as a narrow transcription of the precise sounds of this language, which he sought to reconstruct by treating the Sino-Xenic and modern dialect pronunciations as reflexes of the Qieyun categories. A small number of Qieyun categories were not distinguished in any of the surviving pronunciations, and Karlgren assigned them identical reconstructions. Karlgren's transcription involved
11330-440: The standard language of the late Tang dynasty. The preface of the Qieyun recovered in 1947 indicates that it records a compromise between northern and southern reading and poetic traditions from the late Northern and Southern dynasties period (a diasystem ). Most linguists now believe that no single dialect contained all the distinctions recorded, but that each distinction did occur somewhere. Several scholars have compared
11440-453: The standard reading pronunciation during the Tang dynasty , and went through several revisions and expansions over the following centuries. The Qieyun is thus the oldest surviving rhyme dictionary and the main source for the pronunciation of characters in Early Middle Chinese (EMC). At the time of Bernhard Karlgren 's seminal work on Middle Chinese in the early 20th century, only fragments of
11550-411: The tactics and strategy of the game. Except where noted, the basic rules presented here are valid independent of the scoring rules used. The scoring rules are explained separately. Go terms for which there is no ready English equivalent are commonly called by their Japanese names. The two players, Black and White, take turns placing stones of their color on the intersections of the board, one stone at
11660-449: The time the game reached Korea in the 5th century CE and Japan in the 7th century CE. Go was considered one of the four essential arts of the cultured aristocratic Chinese scholars in antiquity. The earliest written reference to the game is generally recognized as the historical annal Zuo Zhuan ( c. 4th century BCE). Despite its relatively simple rules , Go is extremely complex. Compared to chess , Go has both
11770-500: The voiced fricatives /z/ and /ʐ/ are not distinguished from the voiced affricates /dz/ and /ɖʐ/ , respectively, and the retroflex stops are not distinguished from the dental stops. Several changes occurred between the time of the Qieyun and the rime tables: The following table shows a representative account of the initials of Late Middle Chinese. The voicing distinction is retained in modern Wu and Old Xiang dialects, but has disappeared from other varieties. In Min dialects
11880-435: The vowels in "outer" finals were more open than those in "inner" finals. The interpretation of the "divisions" is more controversial. Three classes of Qieyun finals occur exclusively in the first, second or fourth rows of the rime tables, respectively, and have thus been labelled finals of divisions I, II and IV. The remaining finals are labelled division-III finals because they occur in the third row, but they may also occur in
11990-407: Was straight and low, ... the rising tone was straight and high, ... the departing tone was slightly drawn out, ... the entering tone stops abruptly Based on Annen's description, other similar statements and related data, Mei Tsu-lin concluded that the level tone was long, level and low, the rising tone was short, level and high, the departing tone was somewhat long and probably high and rising, and
12100-625: Was the first to attempt a reconstruction of the sounds of Middle Chinese , comparing its categories with modern varieties of Chinese and the Sino-Xenic pronunciations used in the reading traditions of neighbouring countries. Several other scholars have produced their own reconstructions using similar methods. The Qieyun system is often used as a framework for Chinese dialectology. With the exception of Min varieties, which show independent developments from Old Chinese, modern Chinese varieties can be largely treated as divergent developments from Middle Chinese. The study of Middle Chinese also provides for
