Ponnuki
Importance: ★★★
Diamond shape that is created after four stones capture one
Ponnuki in Go refers to a specific board formation resulting from the capture of a single stone. This distinctive shape, resembling a diamond, is highly valued for its strategic potential, as it exerts influence in all directions and can significantly strengthen the player’s position.
When a player captures a single stone, the remaining stones around the captured point form a diamond-like shape. This shape is celebrated for its efficiency and ability to control surrounding areas.
The Go proverb “A ponnuki is worth thirty points” underscores its importance. While not always literally worth 30 points, the proverb highlights the strength and influence of this formation in shaping territory and controlling the board.
Ponnuki is effective in both offense and defense, often serving as a base for further development or a tool to stabilize a group.
