vs Yamashita, Lee Sedol fights dangerous ko.

At move 95, if W B8, spot the eternal life!

Lee Sedol favors quality of life versus eternal life.

No eternal life here.

lee sedol settled for ko, but if W can't fight the ko, eternal life is the next best

the solution is

W B
B8 B12

once W runs out of ko threats:
D6 B6
B9 A6
C6 B8
D6 B6

etc

I assume B12 should be A12 and B9 should be A9 in above sequence. However, this "eternal life" can only exist assuming both players have no other ko threats. Still, it's a fun sequence.
