In the 51st Go Master League, organized by Asahi Shimbun, Mitsuki Katsuya 9th Dan delivered an impressive performance by defeating Koutarou Fukuoka 7th Dan with a significant advantage in just 159 moves, leading his league record to 2 wins and 1 loss. Katsuya's return to top form was evident as he effectively executed a strategy that showcased his aggressive style, which had previously made him a prominent figure in the world of Go. Katsuya's match demonstrated a unique opening where both players engaged in a territorial struggle typical in Go, but it was Katsuya who maintained the upper hand by focusing his attack on the center, targeting Fukuoka's white stones. His decisive moves, particularly in disregarding his corner stones to concentrate on the central assault, highlighted Katsuya's tactical acumen and decisiveness in competition. Fukuoka, who had burst onto the scene last season as a newcomer competing for the championship, is experiencing a tough outing this season, suffering consecutive losses after starting strong. In contrast, Katsuya has rebounded from an initial loss to win two consecutive matches, creating a stark contrast in their fortunes within the league this season.
