INOUE moved up his left Gold with 2...G-3b and he seemed to select Ittezon Kakugawari in this game . However , INOUE didn't exchange the Bishop's against MURATA's 3.P-2e , but advanced the 8th file Pawn with 3...P-8d .

MURATA exchanged the 2nd file Pawns and the game transposed to Aigakari game . Replying INOUE's 12...P-6d , MURATA dropped a Pawn with 13.P*2d to attack INOUE's camp .

MURATA jumped the right Knight and made NAKAHARA ryu San-Nana Kei senpou attacking form . INOUE ranged his Rook with 16...R-5b aiming at MURATA's King . MURATA attacked the 1st file with 25.P*1d
