122WS notcher
Keywords: Life & Death, Shape
This is a critical notcher. Black can live by playing at the vital point a, after which the two squared points are miai to make a second eye. If the two marked corners of the notch are empty, the same holds true. Anything weaker than this shape (shorter legs, a weak and an empty corner) is dead.
