ken (間, literally 'space') is a Japanese Go term and a measure of distance between two stones.

ken counts the number of empty intersections in a straight line (horizontal or vertical) between the stones. The term is used for almost any combination of stones:

  • For stones of same color
  • For stones of different colors

The term is vocalized when combined with san (3) as sangen. In English, the equivalent word is "space" or "point" (as in one point jump).
