nakade
Pronounced nah-ka-deh. The seven proponent eye shapes as shown in the diagram below (the surrounding stones have been omitted). If the proponent plays on the key points as indicated by crosses, two eyes can be created. Conversely if the opponent plays on the same key points, the eye shape can be reduced to a single eye. The exception is the square four shape which, given alternating proponent and opponent turns, can only ever make one eye. |
