In this game , TSUBOUCHI pushed 9th file Pawn in early stage of game . What does this move mean ? Such an early 1st or 9th file Pawn push is sometimes seen in the games of "Furibisha" players . Why they push a Pawn like this game ? Because some "Furibisha" players dislike an "Ai Furibisha" game .

If the opponent selects "Furibisha" , such a player will select "Ibisha" . In the other hand , if the opponent selects "Ibisha" , he will select "Furibisha" . In both cases , the game will advance "Furibisha" vs "Ibisha" .

After OONO shown the attitude to select "Ibisha" with 2...P-8d , TSUBOUCHI decided to select "Furibisha" . And OONO started making "Ibisha Anaguma" , the most effective tactics against closed and standard "Furibisha" .

While OONO was making "Ibisha Anaguma" , TSUBOUCHI tried making "ISHIDA ryu" formation , but he couldn't . If he moved 16.N-7g , OONO would move B-4b . The Pawn at 7e is difficult to save and the Rook at 7f may be captured , so TSUBOUCHI backed his Rook at 7h again .
(ISHIDA ryu ; a formation with R-7f and N-7g . Bishop is free to positon like 9g , 5g, 3g .)

After exchanging 5th file Pawn , OONO made his "Ibisha Anaguma" more safty advanced and became "Ginkanmuri Anaguma" .
