YAMASAKI selected Aigakari as the opening of this game , and HABU accepted it . After the 2nd file Pawn exchange , YAMASAKI's Rook backed to previous position 2h .

HABU pushed the 9th file Pawn , opened the Bishop line , and moved up the right Silver before the 8th file Pawn exchange . After YAMASAKI's Silver advance to 2g , HABU exchanged the 8th file Pawns . And replying YAMASAKI's 11.P*8g , HABU backed his Rook to 8e .

YAMASAKI moved up his left Silver with 12.S-6h , and HABU attacked in the 9th file such an early stage of the game . HABU's 9th file Pawn got a good position . YAMASAKI tried to recover an advantage , backed 2g-Silver with 14.S-3h and floated his Rook with 15.R-2f . YAMASAKI tried to make his Rook useful and to make his King safety . But HABU also naturally developed his camp .

The difference between both players Rook and Bishop usefulness perhaps gave HABU a slight advantage .

HABU naturally developed his camp and started attacking with 25...P-1f . HABU attacked the left side of YAMASAKI's camp and in the same time HABU's right Silver drove YAMASAKI's Rook . Then YAMASAKI's Rook and Bishop became completely useless .
