Koyama Kuya7-dan

"Both parents are professionals: a journey to find his own move."

Knowing "Grew up in a Go family, with Koyama Ryugo 7-dan as father and Koyama Terumi 7-dan as mother" from the official profile makes Koyama Kuya's games look a little different. I want to watch where they seize the flow and how they move the game.

MIRUGO WATCH POINT

For this player,
watch for this.

The fun is using the family's and teacher's records as an entrance, then looking for moves that resemble them and choices that are all his own. With Koyama Kuya, I also want to see where the decisions that lead to a path like Grew up in a Go family, with Koyama Ryugo 7-dan as father and Koyama Terumi 7-dan as mother appear.

The core you can confirm in the Nihon Ki-in's official profile: "Grew up in a Go family, with Koyama Ryugo 7-dan as father and Koyama Terumi 7-dan as mother." MIRUGO uses A Go family, teacher and student, choices all his own as the entrance to watching, and introduces the choices in each game rather than boxing the player into one style.
