Zerodan: Hi, I played Time mode for 5k on FAST level and there was two time same phenomenon. The first problem was skipped. Both time I have correctly solved it. It seems to be a bug.
caranthir: I added D19, D18, E18, F19, E19 as an alternative response and variation. The opponent doesn't just act plain stupid but makes a sente seki.
I disagree with your comment.
