World No. 1 Go player Shin Jin-seo defeated KataGo, the world's strongest Go artificial intelligence (AI), in a historic exhibition match Tuesday, becoming the first human to win an official match against the AI under the tournament's handicap format.

Shin, 26, defeated KataGo by 11.5 points after 221 moves in the decisive third game of the Ssen Math-Hankyung Gisin Championship, held at the Korea Economic Broadcasting studio in central Seoul.

Although Shin played the three-game series under a two-stone handicap, he rebounded after losing the opening game to claim victories in Games 2 and 3, securing a 2-1 comeback triumph. The result marks the first official series victory by a human player over KataGo under the competition's conditions.

Shin received an appearance fee totaling 150 million won ($108,000) for the three games, along with a 50 million won bonus for each victory, bringing his total prize money to 250 million won. He also received a Genesis G90 luxury sedan for winning two games.
