(diagram 1)

ITOU advanced his Rook Pawn 1.P-2f & 2.P-2e . Such a line rarely seen , when Sente declined Gote's Gokigen Nakabisha . SATOMI naturaly replied with 1...P-3d & 2...B-3c to decline the 2nd file Pawn exchange .

When ITOU opened the Bishop line with 3.P-7f , SATOMI moved up her left Silver with 3...S-4b . If ITOU exchanged the Bishops , the game would advance like following moves ; 4.Bx3c+ Sx3c , 5.K-6h R-4b (or 5...R-2b) . In this line , Sente lost 1 move from standard Kakukou Furibisha ( see Yamajunn's Basic Shogi opening ) . This is because ITOU didn't exchange the Bishops . He moved up the King with 4.K-6h to start making Kakoi .

SATOMI pushed the 5th file Pawn with 4...P-5d without closing her Bishop line . You may think ITOU could make a promoted Bishop by following moves ; 5.Bx3c+ Sx3c , 6.B*5c . But after 6.B*5c , Gote can prevent Sente's Bishop promotion ; 6...B*4d , 7.Bx4d+ Px4d , 8.B*4c B*3b , 9.Bx3b+ Gx3b , 10.B*5c B*4b , 11.Bx4b+ Kx4b . Then ITOU continued making his Kakoi with 5.K-7h .

Until SATOMI's 6...P-5e , the game completely transposed to a variation of Gokigen Nakabisha . ITOU made Funa gakoi and disturb the 5th file Pawn exchange by 9.S-4g . SATOMI made Kata mino gakoi and advanced her left Silver in the 5th file .

After moving up the right Gold with 13.G-6g , ITOU advanced the right Silver with 14.S-3f and crashed it with SATOMI's 5d-Silver .

SATOMI captured ITOU's Silver with 15...Sx4e to disturb capturing the 3d-Pawn . After moving up the left Gold with 16...G-4b , SATOMI dropped a Silver with 17...S*4g aiming at both 3f-Pawn and 5f square .

ITOU started attacking with 18. P-2d & 19.P-3e . SATOMI captured the 2d-Pawn with 18...Bx2d . Against the 3e-Pawn , she didn't capture it , but jumped the left Knight with 19...N-3c to join attacking . But the 19...N-3c was a questionable move . She should simply capture the Pawn with 19...Px3e .

ITOU dropped a Silver with 20.S*5h to defend the 5th file . SATOMI promoted her silver with 20...S-3f+ , but the promoted Silver left from attacking position . ITOU moved up his Bishop with 21.B-9g to use the Bishop . SATOMI floated the Rook to protect the 6d-Pawn .

ITOU pushed the 6th file Pawn with 22.P-6e and captured the 6d-Pawn with 23.Bx6d threatening the 4b-Gold . SATOMI moved her Gold with 23...G-5b and allowed ITOU promoting his Bishop , but SATOMI should avoid the promotion with 23...G-5c . SATOMI moved her promoted Silver with 24...+S-4f to join attacking in the 5th file . But ITOU's Pawn drop on 4g disturbed it .

SATOMI tried to continue attacking with 25...+S-3g . After some moves , SATOMI captured ITOU's Rook , but her promoted Knight left from ITOU's Kakoi . She should promote her Pawn with 33...P-2i+ instead of 33...+Nx3i .

After some moves , ITOU killed SATOMI's Rook ,and SATOMI dropped a Rook with 39...R*3i and tried to attack ITOU's camp .
