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 .

After a Bishop exchange , KAI backed her Rook with 26.R-5i and ISHIBASHI tried to attack KAI's camp by dropping a Pawn , a Bishop and a Silver . However , KAI floated her Rook with 29.R-5f and ISHIBASHI's attack seemed less effective .

After some moves , KAI succeeded to make a promoted Rook .
