In the first game of his retirement baduk (go) match with Korean AI Handol, Lee Sedol found a bug in the AI – it failed to read a net and was forced to resign. Yay, Lee Sedol! You can watch game analysis on Go Pro Yeonwoo. Lee Sedol took 2 handicap stones in the game but gave 7.5 points komi.
Curiously Lee Sedol’s winning move was move 78. It was also move 78 when Lee Sedol made his so-called “divine move” in the game in which he defeated AlphaGo. Handol is apparently stronger than AlphaGo.
