OOSHIMA led the opening to "Ittezon Kakukawari" but YAUCHI declined it by P-6f . The game transpositioned to "Yagura" opening and diagram became just Sente-Gote reversed to "Shin Yagura Niju-yon te gumi" . Many professional shogi players perhaps think this formation is relatively not so good for Sente .

(diagram 2)

OOSHIMA advanced his right silver to 7c and exchanged 7th file Pawn by bishop . This moves set is preparation of making one of the formation of "Yagura Kuzushi" .

YAUCHI also advanced her Silver to 3g , but she didn't exchange 3rd file Pawn . I think she should do so . Then only OOSHIMA could make "Yagura Kuzushi" formation and YAUCHI delayed making her attacking formation .

After 82 moves OOSHIMA won this game .
