    Elizabeth:
    After wA17, bA16, wA12, black has a tesuji at bA18. After the tesuji if wB17 then bB19 starts a ko. If, instead, white takes with wA19, bB17 starts another ko which is dangerous for white.
    Ivan Detkov:
    I agree. Although the risk of ko is asymmetric, it could be a viable strategy. I corrected the sequence.

    I don't see why A17 (or A3 in the sgf file) is inferior to the correct solution A18. In fact it seems with A17 one can get one more point (in gote)
