KataGo's 16% Blunder: B16 Instead of D8 at Move 31

Black was already behind — then played B16, handing White an insurmountable lead. KataGo's analysis shows D8 was the only move to keep the game alive, with a forcing sequence through C3 and D4. The position demanded precision reading. B16 looked like solid corner territory, but it ignored the urgent middle-game fight. After White's response, Black's win rate collapsed from 25% to 9%. Watch how one quiet-looking move in the opening can seal the outcome before the middle game even begins. #KataGo #Go #Baduk #Weiqi #GoAI #AIvsAI CC subtitles available in: English / 中文 / 한국어 / 日本語 Turn on CC for move-by-move AI commentary. 章节 / Chapters: 00:00 Opening 00:58 Move 27 · key moment 02:21 Move 31 · key moment 03:24 Move 34 · key moment 05:37 Move 60 · key moment 07:57 Move 91 · key moment 09:30 Move 96 · position estimate
