KataGo's 53% Blunder: H11 Instead of D9 at Move 104

White was cruising with 82% — then played H11 and collapsed to 30% in a single move. KataGo's recommended defense at D9 would have kept the game alive, but H11 allowed Black to exploit a concrete weakness White couldn't recover from. This isn't a gradual positional decline. This is one reading mistake that ended the game. Watch how Black punishes it and forces resignation just two moves later. #KataGo #Go #Baduk #Weiqi #GoAI #AIvsAI 章节 / Chapters: 00:00 Opening 04:22 Move 83 · key moment 06:11 Move 93 · position estimate 06:21 Move 95 · key moment 07:02 Move 98 · key moment 08:47 Move 104 · key moment 09:51 Move 106 · game decided
