    Why is T3-T2-S1-R1-R2 considered wrong here even though it is the best way to get ko?

    I think a good solution has been removed - t3 t2 s1 r1 r2

    Variation C1 B1 B2 C2 A1 D1 A3 is a ko where white captures first. This is much worse than starting with A3 A2 B1 C1 C2, but both are marked as correct solutions.
    caranthir:
    I removed solutions where white takes the ko first and added "best ko" hint. In the solutions that remain, there are still some qualitative differences left behind in regard of possible local ko threats, though.

    Variants where ko is unfavorable for attacker should not be marked as correct, as they are obviously inferior.
    caranthir:
    Can you point out the specific variation(s) (sgf).
