KAI pushed the 5th file Pawn with 1.P-5f to make a Nakabisha formation . ISHIBASHI allowed KAI to get a Kurai of the 5th file .

ISHIBASHI moved up her right Silver with 4...S-6c to decline the 5th file Pawn exchange and developed her camp without moving her King . In other words , ISHIBASHI seemed to make ITODANI ryu Migi Gyoku formation .

After the King's move onto 2h , KAI advanced the 4th file Pawn with 13.P-4e to start attacking ISHIBASHI's camp .
