Herman Hiddema / Handicaps and komi for other board sizes

Sub-page of HermanHiddema

A suggested list of handicaps and komi to use for difference board sizes. DGrd is the difference in the number of dan and/or kyu grades. DRat is the difference in Rating (EGF style), allowing for half stone differences. Negative komi means komi for white, positive is komi for black (in addition to the handicap). Handicap 0, for even games, means colors should be decided externally, e.g. by nigiri. Handicap 1 means the weaker player starts.
