lavalyn 17k again - maybe I should stop submitting these spoilers.
The eyespace around a is a false eye. To live, White must make two eyes in the larger space that contains three black stones. Black 1 hits the vital point of the position.
We'll fill up some liberties - then...
White dies with a bulky five shape.
Even if Black doesn't play again in this area (Black 2 elsewhere) White still dies with a squared four.
If White takes the vital point, she forms a seki. An attempt by Black to kill the group instead yields either a bent four or a twisted four both of which are live shapes. These are shown in the failure diagrams below.
(Black two elsewhere) If White doesn't understand seki and attempts to capture using 1 and 3, then White is left with a bent three; Black can now kill White by playing back at the marked point. unkx80 adding one failure diagram.
Playing at 1 does not help. White 2 occupies the vital point, and White lives in the shape of twisted four. Easco adding another failure diagram.
Playing at 1 in this diagram doesn't help either. Again, White 2 occupies the vital point, and White lives in the shape of bent four.
