One surprising attack of Side Pawn Picker (Yokofutori)

Side Pawn Picker (Yokofutori), shown in figure. 1, is said to be difficult tactics for amateur players to master because this is so rapid game and there is a risk you are defeated at once resistlessly if you take an even small mistake.
However, to put it the other way around, it is possible for you to attack so rapid and defeat the opponent.
Here one surprising attack is introduced which you can use when the opponent plays Side Pawn Picker.

figure. 1

I will introduce the strategy of gote, so kifu and board is shown in the view side of gote with inverting the board.
The opening of Yokofutori is, P-3d, P-7f, P-8d, P-2f, P-8e, P-2e, G-3b, G-7h, P-8f, Px8f, Rx8f, P-2d, Px2d, Rx2d, Rx7f (figure. 1). The name "Side Pawn Picker" derives from this final movement taking the side Pawn of Rook.
In the ordinary Joseki, the next movement in figure. 1 is B-3c in order to prevent B-8h+.
However, I will introduce one surprising attack which is categorized in Side Pawn Picker Bishop*45 strategy. At the begging of this, in the figure. 1, Bx2b+, Sx2b, P*8b, Sx8b, B*6e (figure. 2). The name "Bishop*45 strategy" derives from this final movement which is B*4e in actual direction board.

After figure. 2, R-8f, Bx4c+ (figure. 3). Bx4c+ is a strong attack.
If the opponent take Gx4c, you can attack by Rx2b (figure. 4).
In other hands, if the opponent will move P*2c in figure. 3, you have an advantage by +Bx3b, Px2d, P*8h.

After figure. 4, the Joseki is Rx8i+, +Rx2a, P*4a, N*5e, G-4b, S*4c (figure. 5). You can attack in this way.

However, in fact, it is said that the opponent have an advantage in the position of figure. 5 by good move G4b-5b.
But the move G4b-5b is very difficult to play if he doesn't know and I guess that not so many amateur players know Joseki perfectly, so I think this attack is effective in amateur championship.
If you have a chance, let's try this.

My real game against 2 Dan player is shown below as an example. The opponent couldn't succeeded to defend perfectly, so I won this game by only 36 moves!
