kaspar: This doesn't seem like "easy life" anymore. It's ko. I'm guessing the original black move was A16 and white can live with: C19B14A18A15 (which also doesn't seem "easy") but it doesn't appear in the review so I'm just guessing.
Guennou: Can't White make a ko here ?
With B15C15C16A15 ? I see that there is no indication on that problem, but here it seems that White does not try the strongest defense.
