Shin Jinseo Defeats AI KataGo, Echoing Lee Sedol's Historic Triumph

Korean Go prodigy Shin Jinseo has achieved a remarkable victory against KataGo, one of the most advanced Go-playing artificial intelligences. In the final match of the SensuHak·Hankyoreh Gishinjeon (God of Go match), Shin, playing with the black stones, defeated KataGo by 11.5 points after 221 moves.

This win marks a significant moment in the ongoing human-AI confrontation in Go. After losing the first game on the 17th, Shin Jinseo staged a dramatic comeback, securing victories in the second and third games. This 2-1 series win against KataGo, which has shown a dominant record against professional players in handicap matches, is drawing parallels to Lee Sedol's historic 2016 win against Google's AlphaGo. Many see Shin's achievement as carrying similar weight and significance.

Reflecting on the match, legendary Go player Lee Sedol acknowledged Shin Jinseo's exceptional skill. "Shin Jinseo 9-dan was perfect," Lee stated in a phone interview. He also observed that the matches revealed weaknesses in the AI's algorithms. "The problem with the AI became apparent in the second and third games," Lee noted, attributing it to algorithmic issues. Lee's perspective adds a layer of expert analysis to Shin's triumph, emphasizing both the human player's brilliance and the AI's limitations.
