The Korea Baduk Association, a body for South Korean Go professionals, had received advance applications for an explanatory event of the match, but the limit of 60 seats had already surpassed.

South Korea's public broadcaster KBS plans to broadcast live the match from 12:40 to 5 pm, extending its initial plan to air it for two hours from 3 pm due to great interests from the general public. It is unusual for the public broadcaster to broadcast live the Go game for more than four hours.
