The komi for 9x9
  • mmKALLL at 2015-10-10


    I'm starting to get a bit bothered by the lower komi for 9x9, even though black's advantage is undeniably much stronger on the small board. The counter-argument is that there are less points on the smaller board, so each komi point also has a far larger impact on the game. However, most high-dan players advocate 6.5, if not 7 or even 7.5 points of komi for the 9x9. Since games tend to be much more even than on 19x19, the difference of single points in tactical decision-making is noticeable on 9x9 even in kyu-level games.

    Therefore, I'd like to propose raising the komi for 9x9 to either 6.5 or 7 points. GoQuest, a recently popular service for fast 9x9 games, uses 7.

    ah, interesting…. I wish I had read this (above) before I replied to your post in the other thread ( “Komi pie, lengthening the title?” )… so I would guess you would recommend the same komi (6.5 or 7.0) for 13x13 games too; is that correct mmKALLL?  Does anybody else have any thoughts or opinions on this?

    I guess 6.5 would be alright for 13x13 (most likely better than 5.5), but I believe that to be the least analyzed board size of the three standard ones.

    IDK, but if a komi of 7 is fair for both 9x9 and 19x19, I would guess it is also fair for 13x13. {“fair” meaning it results in equal number of wins for both Black and White in large data-sets of equal skilled players}

    ping (to get the attention of Thule )

     - anybody have any other thoughts?

    Well, I don't know about komi on 13x13 and 19x19, but on 9x9 it should be exactly 7 to be fair.

    I know that a draw is possible then, but with ideal play, they all draw with komi 7.

    And 6.5 is way better than the 5.5 OGS uses ;o)

    It is slightly favourable for black, while 7.5 is slightly favourable for white.

    So I am for komi on 7 of keeping it like it is (white is normally the stronger player and must be able to beat that 0.5)
