There have been several discussions about Go being played on other
than the standard (9, 13 and 19 square) gobans.
Whether the desire to play on non-regular gobans comes from the fact
that 'normal' Go is too easy is unknown.
For some of these boards, the rules are slightly changed, but in
general 'normal' Go can be played on them.
More information and several examples taken from past newsgroup
discussions and some internet sites can be found at
