SGF

TherapieGo:
I think this problem should be recorrected in its entirety, as it has a consequent number of correct answers! For the example after R2, Q1, all the following moves work to kill: P1 / Q1 / R1 / S1 / S2 / S3 / T4 but currently only T2 is proposed. I know it's a lot of work, so I've tried to rework the SGF file entirely.

Added Q19 and P19 as an alternative to R19.

E19 should also be allowed here. Not just E18.
