HAYAMIZU pushed the 1st file Pawn with 2.P-1f to wait HONDA's decision about formation . HONDA pushed the 8th file Pawn with 2...P-8d to show her attitude to select Ibisha .

HAYAMIZU moved up the left Gold with 3.G-7h and HONDA pushed the 1st file Pawn with 3...P-1d . When HAYAMIZU moved up her Bishop and left Silver , the opening of this game seemed to become unorthodox Kakugawari line .

However HAYAMIZU backed her Bishop with 8.B-5i and advanced the 2nd file Pawns to make an attacking form . HONDA also advanced her right Silver and captured the 7f-Pawn by the Silver with 14...Sx7f . HAYAMIZU pushed the 3rd file Pawn with 16.P-3e to start attacking .
