tl;dr: Shin Jin-seo, the world's top-ranked Go player, defeated KataGo 2-1 in a three-game series with a two-stone handicap, becoming the first human to win an official series against a top-tier Go engine under such conditions. Shin succeeded by abandoning attempts to imitate AI play in favor of a disciplined, defense-oriented strategy focused on territory. The win is seen as a symbolic rebound for humans nearly a decade after AlphaGo's dominance, though it required handicap conditions given the acknowledged skill gap.
