This is the phase where KataGo made the worst mistake by failing to search a mere 30~40 moves. Incidentally, FineArt also failed to come to the correct conclusion, so this seems to be a problem for all Zero AI.

Below: Both players and commentators correctly judged that White won by one move. Situation: A huge race from the lower right to the upper side, but at this phase, White has already won the race. (Finally, it becomes ko fighting by H13, and White wins by using the ko-threat of O4. This conclusion cannot be reversed.)
