I discovered a number of different kifus floating around online for a match played around 1667-68 between Hon'inbou Dousaku and Yasui Chitetsu. I have tried to collect these kifus and their sources below in order to figure out which kifus are most credible.

Every distinct kifu is shown to the left, with bullet points to the right documenting every instance in which that kifu has been reproduced.

Here is my takeaway based on the information I have:

  • We possess only one textual record for the game, which is represented in Enkakusha.
  • Variant kifus are the result of knowledge judgments about the game that the match must have been played differently.

My reasoning is as follows:

  • Although Enkakusha may itself be the result of errors and edits, it is the baseline as the earliest record I have been able to find.
  • No kifu that I have found indicates the existence of any alternate textual record.
    • Fukui in Nihon Kiin 1991a gives Enkakusha as the main kifu. Fukui also gives a variant, Nihon Kiin 1991b, that he says is the result of his own judgments.
    • Fukui in Nihon Kiin 2003 gives Nihon Kiin 1991b and adds in the endgame sequence that was not given in Nihon Kiin 1991b. He only states that he has corrected the sequence of moves found in Nihon Kiin 1991a.
    • Fairbairn's kifu follows the variant sequence but lacks the two moves of S15 and R10. Fairbairn told me that his kifu may have originated from a Professor Araki's Collected Games, but I have been unable to find that this source exists. Given my beginner-level Japanese, that may not mean anything.
    • Brouwer's kifu is identical to Nihon Kiin 2003 and may originate from there. His statement that Dousaku was White and won by 2 points, however, is a discrepancy with Nihon Kiin 2003, and I have found no record that corroborates Brouwer's statement.
