Largest capture that still can't live / Solution 2

[Diagram]
Throw-in (B2 takes 16)  



[Diagram]
White kills  

a and b being miai.

Robert Pauli: The original solution plays B8 at a and, of course, W9 at b, but this one creates more ko threats (if kept in reserve, of course). Not the topic, but anyway.


Robert Pauli: Here's why W3 (above) shouldn't capture the stone (side topic):

[Diagram]
White slips: ko  



[Diagram]
6 internal threats  

Ko fights after each white move skipped. Pretend that Black loses each and has no escape.

But even if Black had no hope to win the ko, a ko wouldn't be in the "rules": after capture, the eye must be unconditionally undividable.

[Diagram]
White can't avoid ko  

Black either lives with a or b.

Nice variant, but only seki
