White plays on the leg side at the second line. White lives up to 7. If next Black 'a' ...
White can atari at 4 and Black can't connect at the marked stone, due to damezumari.
Bending in from the side without leg leads to ko. If Black wins the ko, he almost fills White's eyespace with a BulkyFive. The points 'a' and 'b' are miai for that purpose, and thus serve as a ko-threat for White:
W 1 is a ko threat. If B 2 fills the ko, W 2 makes seki.
This is problematic:
If Black plays 'a', White captures a living nakade. If not, White makes seki at 'a'. Let's discuss at KanazawaDiscussion70.
White must win the ko to be able to approach at 'a'.
