sagari

Sagari is a move that extends downward toward the nearest board edge from an existing stone or group. It is usually played directly below the stone or group, following the direction of the edge rather than merely moving lower in a diagram.

The stone is placed on a line leading toward the edge, commonly as a one-space extension. The exact distance and orientation depend on the position. A sagari may extend a group, help secure territory near the edge, or improve connection and liberty potential.

The name describes the move’s directional relationship with the relevant board edge. Thus, it should not be confused with an ordinary extension away from the edge; which direction counts as descending depends on the edge toward which the move is made.
