KataGo's 40% Blunder: Q7 Instead of R6 at Move 93

Black was holding on with 45% winning chances. Then Q7 happened — and everything collapsed to 5% in a single move. KataGo recommended R6, which would have kept the game alive through a complex sequence: Q6, Q5, S15. Instead, Black played Q7 and handed White the game. This is what a 40-point swing looks like when the reading goes wrong. #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 00:51 Move 25 · key moment 02:34 Move 39 · key moment 05:18 Move 82 · key moment 06:39 Move 87 · position estimate 06:44 Move 88 · key moment 08:12 Move 93 · key moment
