I would like some advice on the game:
I am Black and lose by 9.5 points (my opponent resigned during stone removal and you are welcome to find an explanation for it as they don’t seem to have a sandbagging history, but that does not change that I lost by 9.5 points).
Some remarks and questions:
I play Chinese opening and my opponent invaded at move 12. I was not sure how to handle this invasion, so I tried to lean on the top before attacking the invader. However, my leaning attack didn’t look completely right to me, I suspect that my opponent reacted too weakly to it, so I would like some feedback on this sequence.
At move 49 again, I think that it was not good which did not come completely apparent because my opponent probably did not punish it enough, but let me keep all the moyo from the previous chase. It is possible that they counted and decided that it was enough, but that seems unlikely.
Was move 67 the right choice or should I have taken a side of the corner in change for a little reduction of my moyo?
Move 69: Should I have started the ko at all? Or maybe later?
