NAGASAWA quickly advanced his Rook Pawn onto 2e forcing ABE to move up the Bishop with 2...B-3c . And the opening of this game seemed to be a variation of Kakugawari .

NAGASAWA immediately advanced the right Silver onto 4f making Hayakuri Gin attacking formation , without exchanging the Bishops . Then ABE exchanged the 8th file Pawns and Bishops .

NAGASAWA exchanged the 3rd file Pawns and ABE made Koshikakegin form . NAGASAWA made Ginkanmuri and developed it to Gikanmuri Anaguma .

ABE pushed the 6th file Pawn to exchange the Pawns .
