No Result

    Keywords: Ko, Rules, Go term

No result (J. mushoubu, 無勝負) is a rare game outcome where neither player is considered to have won; and the game is not counted in official results and is replayed. Most commonly it occurs due to repeating whole board situations such as triple ko, quadruple ko, or, more rarely, eternal life. Under Japanese rules (Article 12), such a repeating position becomes a no result if the players agree. Other rulesets contain different provisions.

Although a no result game is not counted in the player's results (unlike jigo), it is still an official game, and receives, for example, its own number in a series. In a best-of-seven match with a no result game, the last game will be considered Game 8.

Occurrences in professional games

  • From the inception of the Nihon Kiin on 24th July 1924 till 30th June 2007, there have only been 19 instances of no result recorded among the 168 813 games played by the professionals, averaging about 1 no result game every 9000 played.[1]
  • In the fourth game of the 1980 Meijin Title, played October 8-9, Cho Chikun, playing against Otake Hideo, retook a ko without an intervening ko threat. Since he had asked the game recorder if it was his turn to take the ko, and the game recorder confirmed that it was, the referee, Ishida Yoshio, in a controversial decision, declared the game to be no result.
