Post subject:  Otake should have captured the cutting stone

While AI bots teach us many new insights, they can also reinforce conventional wisdom. Although it may be coincidental, I found such an example in another game of Otake Hideo, my lighthouse in Go, with the help of KataGo.

Conventional wisdom says: "capture the cutting stone". Its corollary says: "cut the side you don't want" (since the opponent better captures the cutting stone). In this game we can see how Otake's opponent cuts the side he doesn't want and Otake resists by connecting the other side, rather than capturing the cutting stone. According to KataGo, this reduced Otake's comfortable lead of about 13 points to a mere 3 point lead. In the variations, I'm trying to justify KataGo's evaluation.

Go to move 75.
