What is the difference in Go and Mathematical Go?

http://brooklyngoclub.org/jc/rulesgo.html

Is Mathamatical Go a subset of Go as the rules look the same to me as
regular go.

The "Mathematical Rules of Go" are, like the Chinese rules, Japanese rules, NZ rules, Tromp-Taylor rules, Ing rules, etc., a set of rules by which a game can be played.

It is often asserted that the games defined by all these sets of rules are rather similar, at least when played skilfully. This assertion is false. The game defined by the "Mathematical Rules of Go" is significantly different from the (rather similar) games defined by the other rule sets. You will realise this if you consider the position below:

 # # # O . O    entire 6x6 board
 . . # O O .    # to play
 . . # O . O
 # # # O O .
 . . # # O O
 . . . # O .

Using the "Mathematical Rules of Go", O can win with correct play. Under any other rule set, # has already won, or can win with correct play. This effect of the value of one-point eyes is much more significant than that of the "two-stone group tax" mentioned by David.
