Hello all, my first post here!
At the end of this game, there was an undefended cut in white’s position at D2: 2021-04-06. Is it normal to play out these situations until all cuts are defended? I see AI and other players doing this, but in this case black is behind in the race to capture the C2 group, so if white defends preemptively, he is just filling in his territory unnecessarily.
So white passed, and black had the choice whether to threaten, e.g. at C1, in which case white can answer and play out the sequence, saving the white group. In this case black saw he would lose the capturing race and so he passed too. But the position looks unresolved to me (as a beginner), so just wondering if there is some kind of etiquette in this situation.
