Aji

Aji in Go represents latent possibilities within a board position, often tied to weaknesses, defects, or unexploited opportunities. The term translates to “taste” in Japanese, reflecting its subtle and nuanced nature.

Nuances of Aji

Aji is more than just “potential” or “possibility”—those terms might make it seem like any empty space on the board counts as aji, which isn’t true. Aji appears when there are groups already on the board, and at least one has a hidden weakness or unresolved feature that players can use. This lingering tension affects the game until it’s either resolved or exploited by one of the players.

Good Aji reflects strong, flexible positions with latent threats or opportunities. These can serve as offensive tools, allowing players to control or threaten critical areas. Bad Aji arises from weak shapes or thin groups, leaving openings for the opponent to exploit.

Mismanagement of aji can lead to inefficiency or unintended consequences:

• Aji-keshi: Prematurely removing the opponent’s aji can strengthen their position unnecessarily.

• Honte: Resolving one’s own aji at the right moment stabilizes groups and prevents exploitation.
