NAKAMURA closed her Bishop line with 3.P-6f and swung her Rook with 4.R-6h making Shiken Bisha form . YAUCHI made Funa gakoi and NAKAMURA made Kata mino gakoi .

YAUCHI moved up her Bishop with 9...B-3c and Lance with 11...L-1b to develop her Kakoi to Ibisha Anaguma . Replying YAUCHI's 11...L-1b , NAKAMURA reopened her Bishop line with 12.P-6e (some times called Roku-Go Fu pon ) to face the Bishops .

YAUCHI declined the Bishop exchange with 12...P-4d , because the Bishop exchange would make the defect to be dropped a Bishop after making Ibisha Anaguma .

While YAUCHI was making Ibisha Anaguma , NAKAMURA advanced her left Silver threatening an attack at 6d . YAUCHI backed her Bishop with 15...B-4b to defend the 6d .

NAKAMURA moved up her left Gold to develop her Kakoi (Hon mino gakoi -> Taka mino gakoi -> Ginkanmuri ) . YAUCHI advanced the 3rd file Pawn 17...P-3e to disturb the development of NAKAMURA's Kakoi .

After completed making Ibisha Anaguma , YAUCHI drove away NAKAMURA's 7e-Silver and prepared the attack in the 6th file . NAKAMURA exchanged the 3rd file Pawns and YAUCHI started attacking with 25...P-6d .
