Compendium of Rules for Wei-Qi (Go, Baduk)

Wilfred J. Hansen

The common go maxim

GO: An hour to learn; a lifetime to master.

badly underestimates its times. No one has yet mastered the game in a single lifetime. And learning the rules, I have discovered, takes more than an hour. Indeed, I have spent two years trying to find out what the rules ARE. In the process, I have collected the various different rule sets available here.

For the various options that differ between rule sets, see Fotland's Summary and the British Go Association .
The most elementary (but out-dated) rules are survivor wins .
The most elegant and concise rule set is Tromp/Taylor .

Similar to Tromp/Taylor rules are those of New Zealand, which I don't have, and the American Go Association as stated in Concise Rules and further detailed in Commentary . The American Go Association has also adopted a set of tournament rules .

Japanese rules are from the Nihon & Kansai Kiins .

From The Go Player's Almanac I have excerpted the Chinese Rules .

James Davies claims that "Modern Korean rules are equivalent to the 1949 Japanese rules which are in turn equivalent to the1989 Japanese rules, although formulated differently."

Ing Chang-ki of Taiwan has promoted the SST Laws of Wei-Chi

based on which is my Precise SST Ko Rule
and also the descriptions by Kim Simon Straus and Jasiek .

When comparing rule sets, it is convenient to have a Bestiary of curious positions that pose problems.

Engels has collected a number of rule sets for variants of go.

Spight has proposed that the Mathematical Theory of Go can aid in understanding what any given rule set might mean.
