Rules of Go
The strategic consequences of the rules of Go are generally the same worldwide, even though the text of the rules reads very differently.
Like many other games, playing instructions for go are rather different from a complete and consistent set of rules. Like golf or bridge, the basic thrust of the game is simple, but there are so many situations to cover that a collection of rules that does cover every one of them must seem complex or abstruse. Go is rich in unexpected situations that cannot be anticipated or analyzed except on the basis of long experience.
This page is a listing of technical rules pages on Sensei's Library. Please don't consult these pages if you are looking for tutorials. Any clear exposition of the differences between rival rules quickly becomes legalistic and confusing.

There are also several methods to define the score (result).

When played on a physical board, determining the score involves manually counting. There are different counting methods in use. Some rule sets prescribe which counting method must be used, others do not.
