With 2...B-3c , ISHIBASHI selected Yonteme San-San Kaku senpou as the opening of this game . TSUKADA immediately exchanged the Bishops with 3.Bx3c+ and moved up his left Gold with 4.G-7h to decline ISHIBASHI's 4...R-2b . If ISHIBASHI still played 4...R-2b ... , about this line , please see my aonther blog ; Yamajunn's Shogi opening trap .
ISHIBASHI once moved her Rook with 4...R-4b to protect the 4c-Pawn and after the King's move 6.K-7b protecting the 8c-Pawn she moved her Rook again with 7...R-2b , making the Mukai Bisha formation .

TSUKADA advanced his Rook Pawn with 7.P-2e and moved the King with 9.K-8h to make his Kakoi . But before TSUKADA completed the Kakoi , ISHIBASHI started attacking with 11...Nx2e , Ni-Go Kei pon attack .
