semelis: Upper left, white to play.
After white plays kikashi at E19, B19, A17 and captures.
What happens if black, instead of A14, plays D15 ?
Rushing to F19 doesn't work, so white A15 must escape to some friends or, as it is, white dies.
d4rkm4tter: ... A15-D15-A14 your group can't be killed. With no friends on the side of the board, running to the corner would still make you 3 liberties vs 2 because the opponent can't approach either side.
