第6条 禁止全局同形 着子后不得使对方重复面临曾出现过的局面。
This appears to be a superko rule in the Chinese rules.
With the help of Babelfish I get the idea that a player may prohibit his opponent from playing a stone so that the resulting position would repeat a previous whole board position.
However, from what I hear, the Chinese do not really use a superko rule.
Can someone please explain?
Thanks. :-)
Since this thread was somewhat hijacked (still giving interesting insights, though), I`d like to point out that Bill`s question concerning article 6 is not answered yet. I am curious about it, too. Would any chinese speaker mind to help?
RobertJasiek: Could someone translate the referee ko rules of the Chinese 2002 Rules as precisely as possible, please?
Well, here's my attempt to do a line-by-line translation for the section you're talking about:

Chapter III: Rules of Refereeing
第20条 禁止全局同形再现
Article 20: Repeating a previous full-board position is prohibited.
全局同形再现是妨碍终局的惟一技术性原因,原则上必须禁止。
The re-apperance of a whole-board position is the only technical reason for preventing a game from ending (literally, "for disturbing the termination of a game"). In principle, this must be prohibited.
1、禁止单劫立即回提。
1. Re-taking a "single ko" is prohibited.
[I assume that "single ko" means the following (copied from the "ko" page):]
2、禁止假生类多劫循环(如图三黑A位提劫为假生)。
2. False-life multiple-ko cycles are prohibited. For example, in Diagram 3, black taking the ko at A is "false life."
3、原则上禁止三劫循环、四劫循环、长生、双提两子等全局同形再现的罕见特例(如图四)。根据不同比赛,也可制定相应的补充规定,如:无胜负、和棋、加赛等。
3. In principle, rare cases that repeat the whole-board position, such as triple kos, quadruple kos, eternal life, and kos that involve "double capture of two stones" [literal translation-- I think they're also known as "round-robin kos"], are prohibited-- see diagram 4 for examples. Depending on the tournament, supplementary rulings may also be implemented, such as no result, jigo, or re-match.
Top left: Eternal Life. Top right: Round-robin ko.
Lower left: Triple ko. Lower right: Quadruple ko.
P.S. I hope that this does not constitute a copyright violation...
RobertJasiek: Thank you, this is very helpful! - Usual understanding of copyright is that citations of short parts is allowed. In my opinion, rules are special in that the purpose of rules is to be announced, spread, and used. So normally I think that also complete rulesets that have been announced or used for actual tournaments may be copied. Courts' opinions might differ from mine, of course. Who could predict that?
