Sunday Problem #20

This is a whole-board endgame problem from Ōhashi Hirofumi 6p’s book, (Sōkai! Kachisuji-sagashi) or Refreshing! Searching for the winning play.

If the title sounds strange in English, it is because sōkai does not translate very well; ‘refreshing’ or ‘invigorating’ are technically correct translations, but Western go players would rarely use them for the feeling of relief one gets when finally solving a tricky problem. And, somehow, it seems like ‘relieving’ would hardly make for a good problem book title in the West.

How should we learn from the AI?

My recent work got me again thinking about the nature of learning and understanding. More precisely, I got interested in thinking about the best way to use the ai in go studies.
