Your edit is correct :)

But anyway, living in seki is also a form of living. So if the problem is "black to live" then the seki would be sufficient.
My name is Gijs, from Utrecht, NL.

When in doubt, play the most aggressive move

Yes, but i was confused with "After Black 1, White can't stop him from making to eyes", because seki is no eyes. But now i know :).

We don't know who we are; we don't know where we are.
Each of us woke up one moment and here we were in the darkness.
We're nameless things with no memory; no knowledge of what went before,
No understanding of what is now, no knowledge of what will be.
