Rules

Gomocup has been played in the freestyle Gomoku rule with the board size of 20 since it was started in 2000.{{Cite web|url=http://gomocup.org/detail-information/|title=Detailed Information|last=|first=|date=|website=Gomocup|publisher=|access-date=}} In 2009, the standard Gomoku rule was added into Gomocup as a tournament, in which the board size is 15 and more than five in a row is not considered to be a win.{{Cite web|url=http://gomocup.org/results/gomocup-result-2009/|title=Gomocup 2009, the 10th tournament (April the 4th, 2009)|last=|first=|date=|website=Gomocup|publisher=|access-date=}} In 2016, the Renju rule was also added into Gomocup, with a board size of 15 and forbidden moves for black.{{Cite web|url=http://gomocup.org/gomocup-2016-announcement/|title=Gomocup 2016 Announcement|last=|first=|date=|website=Gomocup|publisher=|access-date=|archive-url=https://web.archive.org/web/20160514045616/http://gomocup.org/gomocup-2016-announcement/|archive-date=2016-05-14|url-status=dead}} In particular, since there are a large number of participants in the freestyle Gomoku tournament, the freestyle Gomoku tournament is divided into several leagues, and the fast game tournament is introduced.{{Cite web|url=http://gomocup.org/results/gomocup-result-2005/|title=Gomocup 2005, the 6th tournament (April the 16th, 2005)|last=|first=|date=|website=Gomocup|publisher=|access-date=}}

To get rid of the fact that there is a winning strategy for the player who plays first in Gomoku,{{Cite web|url=http://www.renju.nu/wp-content/uploads/sites/46/2016/09/Go-Moku.pdf|title=Go-Moku and Threat Space Search|access-date=2017-05-07|archive-date=2016-09-28|archive-url=https://web.archive.org/web/20160928113745/http://www.renju.nu/wp-content/uploads/sites/46/2016/09/Go-Moku.pdf|url-status=dead}} balanced openings have been prepared by Gomoku experts since 2006.{{Cite web|url=http://gomocup.org/results/gomocup-result-2006/|title=Gomocup 2006, the 7th tournament (April the 28th, 2006)|last=|first=|date=|website=Gomocup|publisher=|access-date=}} Games would be started from these balanced openings, and neither side would have a big advantage from the very beginning.

AI vs. Human Tournament

The result was one win, one draw and one loss for AIs, and the total score was 3:3.{{Cite web|url=http://gomocup.org/results/ai-human-2006/|title=The 1st tournament AI vs. Human (November the 11th, 2006)|last=|first=|date=|website=Gomocup|publisher=|access-date=2016-06-02}}
