GO (also called Igo in Japan, Wei-chi in China, and Baduk in
Korea) is an intellectual game of pure skill. It has simpler rules
than Chess, but is a deeper and more elegant game that is well
worth studying.
If you do not know anything about GO, but would like to learn,
my Beginner's Introduction to
GO is now available for browsing on the web. If you prefer,
a 25-page paper version is available in the form of a PDF
file (293k). (The web version, however, contains some additional
information, and links to other places.)
