Example game of Central Rook with Left Bear in the hole (nyanko)

I think Central Rook with Left Bear in the hole is good tactics, so the example game is shown here.
This game was played in 2010, when I was a student.
Experientially, when using this tactics, I'm in a little bad position in opening, but the castle is solid then has potential for turn around.
Although I also don't know much the opnenig of this tactics, it's pleasant if you find this imformative.(If you have an advice, please tell me.)
In this game, Knight had the key role.
