KyuExercise133/Attempts

Sub-page of KyuExercise133

My attempt:

[Diagram]

Without liberty a, 9 at b kill black, with liberty a, 10 at c save black.

[Diagram]

illluck I'm probably missing something obvious, but does "a" actually matter?

2 seems to be only possible defense because all others give either dead shape in corner or connection, but then white can descend at 3 and get eye vs. no eye. Black seems behind by a liberty even with a?

[Diagram]

[Diagram]

Another resistance, but again short a liberty?

[Diagram]

OP what about playing at 6 instead ? 7 at c allows a snapback.

[Diagram]

illluck Ah, right! So I guess with the liberty at a it's a ko for seki?

Just a side note, 2 in first diagram should be at 5 (otherwise 3 at 5 will kill). 8 should be at b, otherwise there's a ko even with liberty at a.
