Numbers are handicap stones. I also have a crude certificate template (I can't remember where I found it) for awarding kyu ranks to children if anyone is interested.

Some time ago I did a little survey of where the star-points are placed on smaller board sizes. While there's no reason handicap stones have to go on the star-points, it seems reasonable to me.

Anyway, here's what I found:

Code: Select all

IGS
    13x13    9 star-points, outer points at 4-4
     9x9     5 star-points, outer points at 3-3

KGS
    13x13    9 star-points, outer points at 4-4
     9x9     9 star-points, outer points at 3-3

DGS
    13x13    9 star-points, outer points at 4-4
     9x9     5 star-points, outer points at 3-3

Senseis Library description of star-points
    13x13    5 star-points, outer points at 4-4
     9x9     5, 4, or 1 star point, outer points at 3-3

Pictures of real boards from YMI
    13x13    5 star-points, outer points at 4-4
     9x9     1 star-point at 5-5

Nihon Kiin
    13x13    5 star-points, outer points at 4-4
     9x9     1 star-point at 5-5
