A nakade (ナカデ or 中手) is a play inside an opponent's eye.

(Written in katakana or kanji in Japanese. Hiragana is wrong. Borrowing is not the only criterion for katakana. Italicisation and replacement for kanji are other uses.)

Examples

[Diagram]
Three points.

Black can kill this group by playing nakade at B1.

[Diagram]
Seki

The nakade sequence, W1 - W3, makes seki.

[Diagram]
Semeai seki

The nakade, B1, makes the result of the semeai a seki.


Unsettled eyeshapes are those eyeshapes where a killing nakade is possible.
Basic living eye shapes are those where a killing nakade (in one move) is not possible.
Dead eyeshapes are those where a nakade is not needed to kill: the group is already dead.

Be aware however that these basic shapes ignore two major effects:

For several possible reasons, the eye shape may contain more enemy stones. Any eye shape which is filled with stones so that almost filling it with a killing shape is inevitable, is dead. These patterns are listed at killable eyeshapes.

A combination of both circumstances can be found at Biggest known eye space for which there is a nakade
