@posetcay The linking function gives the wrong position, so I'll just drop the coordinates here. Doesn't E19 D19 E18 H19 F19 F17 B19 kill?

posetcay:
Added refutation to E19.

Hrewsahgs:
+ D2 D3 C1 G1 D1 B1 E1 If you omit F3 in favor of killing the stones directly, this variation occurs, I believe. If you connect at C1 or make a ko with B1 in response to the D2 atari, then white can play F3 and under the stones will occur.

Hrewsahgs:
+ D2 F3 C1 F5 G5 G4 H5 Is this not a possible line?

Sadaharu:
Just playing at E2 also works instead of G1 followed by E2
