SASAKI led the opening to "Gokigen Nakabisha" . NAGANUMA didn't select major popular tactics against "Gokigen Nakabisha" . SASAKI get the 5th file "Kurai" ; To position the Pawn at 5e , and the opening transpositoned to Gote "Gosuji Kuraidori Nakabisha " . NAGANUMA choiced interesting moves ; G-6h and K-6i . This formation has an idea against Gote's 5th file Pawn exchange ,because move of the King to 6i can become effective ; when Gote exchange the 5th file Pawn , P-5f Px5f Rx5f is not a check .

NAGANUMA developed his right Silver to 4f , SASAKI must move S-4d to keep the balance in 4th and 3rd file . SASAKI became difficult to advance and start attacking move by move .
NAGANUMA made "Ibisha Anaguma" and he got strategically victory , but to win is sometimes very difficult .
