Elwyn Berlekamp, the first to study mathematical Go, says that 'What are the rules? is 'a dangerous question' (video: http://www.msri.org/realvideo/ln/msri/2000/gametheory/berlekamp/1/index.html http://www.msri.org/realvideo/ln/msri/2000/gametheory/berlek..., start at 6:30). For each of the (several) traditional rulesets there are positions that the ruleset can't deal with. So in order to allow a mathematical or computer analysis the rules often need to be tweaked.
