The peep must be answered or Black escapes to the strong reinforcements just outside White's walls. After , Black has two eyes.

Playing either a or b will leave White playing the other point - one eye.

takes away Black's potential eye and prevents the thrust - the rules prevent suicide. Black dies here.

In case the peep is answered differently, the move order changes... eventually White will play at .

Black is the vital point. White has to play at to prevent the capture of the marked White stone(s). From there, Black secures the second eye by playing at . White has the choice of either 'a' or 'b' for the fifth play, but should choose 'a' otherwise White will lose a point of territory. If White tried to close off the potential eye at by playing there after , Black can simply play where is, White can't protect itself from this and will be captured; if White chooses this route then it will lose 3 more points of territory and 2/3 prisoners depending how White chooses to play.
What with this situation ? (if white answers at he still can
prevent black from creating two eyes ...)
