Keima (kogeima)

Keima refers to a move where a stone is placed two points away horizontally and one point vertically (or vice versa), forming an L-shape. This move is similar to the knight’s move in chess. Keima is a versatile maneuver used in both offensive and defensive strategies, allowing players to extend their stones efficiently while staying flexible.

Keima is sometimes referred to as Kogeima to distinguish it from Ogeima (a large knight’s move that covers more distance).

Usage

Keima creates a diagonal connection between stones, which, while not directly connected, offers a balance between speed and stability. It is utilized in attacking to approach and put pressure on an opponent’s stones, limiting their potential expansion. In defending, it is employed to strengthen one’s own groups, aiding in the development of territory and securing weak points.

While the keima is a versatile and commonly used move, it’s important to be aware of the potential weaknesses it can introduce, such as cutting points that opponents can exploit. 

Proper reading and anticipation of your opponent’s responses are crucial when using keima to ensure it contributes effectively to your overall strategy.
