In generally, the formation against Static Rook like as Yagura castle prepares for attack from longitudinal direction, while the formation against Swinging Rook like as Bear in the hole prepares for attack from side direction.
Therefore, Feint Swinging Rook aims to get around the opponent's move.
This tactics is adopted by not only amateur players but also professional players occasionally.
Feint Swinging Rook has some variations and two examples are introduced here.
The case you are gote is shown here (you can use also in the case you are sente, of course).
The opening movement of first example is P-3d, P-3f, S-4b, P-7f, P-4d, S-4h, G-3b (figure. 1).
This opening is typical in Yagura.
After that, you will move like as Static Rook and yet so that you can swing Rook, for instance P-4f, P-5d, S-4g, S-6b, P-3f, S-3c, S-6h, G-5b, P-6f, P-8d, S-6g, P-8e, B-7g, K-4a (figure. 2).
After figure. 2, you will swing Rook by R-8h (figure. 3).
In figure. 3, the opponent's castle is not suitable against swinging Rook, in particular, it's difficult for the opponent to castle in the Bear in the hole.
In figure. 4, you can aim the 4-line.
Next the second variation is introduced.
The opening movement of second example is P-3d, P-3f, S-4b, P-7f, S-3c, S-4h, G-3b, P-6f, P-8d, S-6g, P-8e, B-7g, S-6b (figure. 5).
The 5th move S-3c was prevalent a little while ago.
However, Kouzou Masuda thought that S-3c is not good move if the opponent swings Rook. Therefore Masuda adopted Feint Swinging Rook like this.
In figure. 5, the opponent's castle is against Static Rook, so you can swing Rook by like as R-6h (figure. 6). Incidentally, you can select the position of Rook, not limited in 6h.
After figure. 6, K-4a, K-4h, G-5b, S-3h, P-5d, K-3i, B-3a, G4i-5h, P-7d, K-2h (figure. 7).
The Mino castle in figure. 7 is particularly called "Topknot Mino castle."
This name derives from the Pawn in 2f looks like topknot.
After figure. 7, you can move like as ordinal Swinging Rook, attack on 6-line or form High Mino castle.
Feint Swinging Rook has little normal Joseki and the battle is likely to become true ability game.
If you like that kind of battle, I recommend to use this once.
The example game is shown below. This game is also not normal Joseki battle but true ability battle.
