Ivan Detkov: One of your sequences, which is starting from j5, is just wrong. Another, which is starting from k7, is good but a bit sub-optimal. White just kill 4 stones in gote. There is a better sequence, which kills everything. Your sequence could be treated as a good answer. I will leave the decision to Jérôme here.
