I’m looking at Cho Chikun #29 (https://online-go.com/puzzle/2864) and even though I can easily arrive at the desired position from the puzzle (preventing white from making eye shape), at that point white can easily escape while black is busy winning the ko. I’m confused as to what black is supposed to do next ??? See https://online-go.com/review/278357
This is probably a stupid question, but can anyone point me to where black went wrong in my attempted continuation to the problem’s given solution ? Or alternatively, is there still a way for black to limit the damage from white’s escape ?
