Fair Komi

    Keywords: Rules

Standard Komi assumes a fixed value for every level of play.

Yet it seems that correct komi (0.5/0.5 win chances) for low level play (e.g. random) is lower than standard komi.

Thus fair Komi is not likely to be a fixed value, but should be scaled according so that the winchances at this level of play indeed match '0.5'.

One easy way to attain fair Komi would be to utilize either of these rules:

  • Divide and Choose: "One player chooses Komi, the other one chooses sides."
  • Auction Komi: "Both players secretly bid Komi for moving first. The higher bidding player gets Black."
  • Pie rule: Play without Komi, but have one player play Black's first move, and the other choose to take Black or White.

Yet how should one scale Komi or choose a good value for above rules?

Lacking extensive data on Beginner as well as DDK games, I will now create an experimental table of Halfmovevalues scaled by skill:

  • 9d+ Halfmovevalue = 8 (e.g. RuiNaiwei would pay 8 komi for black)
  • 06d Halfmovevalue = 7 (some amateurs and pro dans want higher komi)
  • 01d Halfmovevalue = 6 (around here the default might be appropriate)
  • 15k Halfmovevalue = 5 (at lower levels the importance is negligible)
