    A18 E18 D19 E19 B18 Instead of playing C19 to end up in ko, can't Black play C18 now?
    d4rkm4tter:
    Yes, white gets a seki here. So it is incorrect.

    Man kann hier ko nicht vermeiden. Auf S19 kann weiß ja einfach Q18 oder S18 antworten. Daher denke ich auch, dass T18 statt R18 der bessere zweite Zug für schwarz ist.
