KAI simply closed her Bishop line with 2.P-6f and IDOH immediately turned her Rook with 2...R-3b making Sanken Bisha formation .

After moving up the Bishop and the left Silver , KAI turned her Rook to 8h , making the Mukai Bisha form . While IDOH was making Anaguma gakoi , KAI made Hon mino gakoi and developed it Taka mino gakoi .

IDOH moved up her Bishop to protect itself by 2a-Bishop and pushed the 4th file Pawn with 25...P-4e to start attacking .

KAI captured the 4e-Pawn with 26.Px4e . IDOH exchanged the Bishops with 26...Bx7g+ , and dropped it with 27...B*2b aiming at the 7g-Knight . KAI floated her Rook with 28.R-8g to protect the 7g-Knight . IDOH crushed the 5d-Silver against KAI's 5f-Silver with 28...S-5e .

Without replying against 28...S-5e , KAI dropped a Bishop with 29.B*4c attacking both the 3d-Rook and the 2a-Knight . IDOH's Rook escaped from the Bishop with 29...R-3a protecting the 2a-Knight .

KAI attacked IDOH's Rook , but IDOH also used her Bishop and Knight effectively and seemed to get an advantage . Sacrificing a Rook , IDOH tried to attack KAI's King , but
the attack became difficult to continue after KAI's Knight drop with 52.N*3i .
