Diagram 8.  Hineri-bisha killer.

One of the countermeasures for White against the hineri-bisha is not to
open its B path. The diagram 8 shows the reason why the hineri-bisha was
unpopular for a certain period of time. What should be noted is: S-7b and
P-9d. White can efficiently solidate its fort, since G doesn't have to move
to 3c to protect P on 3d. Black's R-3f should be one vain move.

A few words about the R-3f: As long as White's R stays at 8f, Black can't
push its P to 7e for hineri-bisha.  Hence, R-3f, so that he can make P-7e.
White should avoid exchanging Rs because of its yet-to-be-solidified camp.
R-3f when there is no P on 3d is called neko-fu-dori (Cat's Fu-Trap), where
R is likened to a cat crouching in front of a hole waiting for a mouse (fu)
to come out.

Instead of R-3f, Black devised a way to force White to pull its R back to
8b, based on the Tsukata Special concept.
