Hrewsahgs: + D2D3C1G1D1B1E1 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.
d4rkm4tter: Oh wow yeah, I added the two sacrifice sequences as correct.
@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?
