YAMASAKI selected Ittezon Kakukawari with 4...Bx8h+ . After moving the King with 7.K-6h , HABU advanced his Silver to 2f , a Bougin attacking form .

YAMASAKI pushed the 1st file Pawn with 10...P-1d , to decline further advance of HABU's 2f -Silver . HABU advanced the 3rd file Pawn to attack in the 3rd file .

HABU started attacking with 12.P-3e . YAMASAKI didn't capture the Pawn , but moved up the 6c-Silver to 5d , Koshikakegin position .

After capturing the 3d-Pawn , HABU didn't attack immediately but moved the King to 7i . YAMASAKI moved up his right Gold with 14...G-5b to control the right half of the board by all Golds and Silvers' power .

HABU also moved up his right Gold with 15.G-5h , to join the defend of his King . YAMASAKI pushed the 9th file Pawn to open the advancing route of the 8i-Knight ; 8i --> 9c --> 8e . In stead of the move , K-4b or P-6e are also effective moves .

HABU backed his 2f-Silver with 16.S-3g to use the Rook forward . Against HABU's 2nd file Pawn exchange , YAMASAKI replied with 18...G-2c . HABU backed his Rook with 19.R-2h . Dropping a Pawn with 19...P*2g , YAMASAKI made a promoted Bishop .

HABU dropped a Bishop with 22.B*1f to threatening 4i-promoted Bishop . Sacrificing a Pawn with 22...P*2g , YAMASAKI forced HABU to move 1f-Bishop , and aimed at 2h-Rook with 23...+B-3i . HABU used the 2g-Bishop to attack in the 5th file .

After some moves , HABU's Bishop and right Silver made a bad formation , and YAMASAKI's King was unprotected . Which player's defect was more critical ? Perhaps the position was still difficult , but YAMASAKI still must attack HABU's bad shape pieces , and in addition to it he had little time to think .
