Chinese Rules
Chinese rules for Go are defined by the Chinese Weiqi Association, mainland China:
-
Chinese 2002 rules (in English)
-
Chinese Rules 2001 edition, published 2007-04-07 (in Chinese) as adopted by the China Weiqi Association
-
Chinese 2002 rules (in Chinese) from CCC Yenching University, Hong Kong
-
Chinese 1988 rules from The Go Players Almanac.
In Chinese rules:
- Suicide is not allowed.
- There is a positional superko rule (in theory), see Positional Superko / Example.
- The referee can void games with complex ko (in practice).
- Chinese counting is used, i.e.
- Area scoring is used.
- Eyes in seki count as territory [1].
The official Chinese rules make no mention of handicaps. Some interpretations of Chinese rules, such as the implementation on KGS, allow free placement of handicap stones.
SAS: Can someone please explain the bit about voiding games with complex ko? Section 6 of the Chinese rules clearly states that repetition of position is not allowed. Therefore the part of Section 20 which states that the referee may declare a draw or a replay if neither side will yield in a triple ko (or quadruple ko, etc.) is irrelevant - the no-repetition rule ensures that one side or the other must yield.
- SAS: Having looked at this a bit more, it seems that there is a difference between the rules as they are written and as they are actually applied. I've modified the above to take account of this.
RobertJasiek: The positional superko is pretence and the referees' ko rules are applied in practice. The latter can be explained by a moderately complex modification of the Japanese 2003 Rules.
Variant:
[1] There is no rule precluding eyes in seki from counting as territory. Such a rule is a feature of other rulesets, such as the Japanese and Korean rules.
