68.11.233.107: Status Question (2010-02-18 20:45) [#7253]

This is a position from a game. Is this an easy answer? I couldn't tell the status at the time.

Phelan: seems dead (2010-02-18 23:10) [#7260]

Phelan: To me (OGS 15k) it looks dead. There seem to be some tricky moves by White, but I think if Black answers correctly there's no way for white to live.

Ugh, once again, looked for complicated answers, and missed the obvious one... :( I stand corrected.

seems to guarantee saving almost everything. After , if captures the 2 stones, white can retake with :

And white manages to save essentially everything.

If black declines the 2-stone capture to attempt a connect-and-die, then white connects with , and has the this sequence to save the day.

If I read correctly, connecting the 2 stones with immediately seems only to get a ko, because black now has the throw-in. But black does risk in this ko as well, though it appears favorable for black.
