Move Bishop to Edge

In figure 1, how do you attack?
By just Px5c+, it is not easy to continue the attack after that.

Moving Bishop to Edge (9f) technique is sometimes effective in Swinging Rook.
I moved B-9f (figure. 2).

This aims severe attack, Bx6b, RX6B, Px5c (figure. 3) and it's not easy to defend. If the opponent will take Px5d, the game follows Sx5d, Gx5d, Rx5d, P*5c, Bx6b (or R-8d) and I can succeed to attack.

After figure. 2, the real game followed N-7c, S-7d, P-9d, B-8d, P-4e, Px5c+, Sx5c, Sx6c+ (figure. 4.)
I succeeded to attack and win after that.

As mentioned above, moving Bishop to Edge (9f) technique is sometimes effective in Swinging Rook.
Then, it is often said "Edge Pawn at the other side of Castle (P-9d) is tactics of Static Rook."
