    Upper left: B15 B16 A18 A17 => E17 C19 G19 considered wrong - why?

    s3,t4,t3,s4.t1,r1,q1,p1.n1 kills as well
    caranthir:
    Looks like S3 must be answered with S4. Updated sequences.

    s5 s4 t2 t3 o1 r1 n1 (first n1 then o1 is already marked correct. so you just change the order of moves)

    todbeibrot:
    Of course Black has to start with s5 and t2. Now r1 and o1 should be correct too.
    d4rkm4tter:
    The objective should be to kill without ko. I found only 2 moves that can accomplish it: R1 and N1. I made all correct sequences new and increased the problem difficulty.
