When White assumes the suzume-zashi formation, Black has to cope with
it by pushing P on the R file, thereby arrives the position shown in Diagram
9. Did you notice the White's positioning was not exactly the same as the
basic one described in Section 1? The difference lies in where the suzume-zashi
side's G stands: the G here stays on 5b instead of 4c.

Diagram 11. Up to (w)P*7d.
Look again at the last move on Diagram 10. According to a theory, the
move for the suzume-zashi player to make here (instead of L*7a) was P-7e.
In this case, however, it won't do, because Black will then play B-4f. L*7a
was a well-thought-out move, which has a story behind it. As a matter of
fact, I was the one who was shocked to see the move for the first time at
the kenkyu-kai (a practice meet in which several pros get together and play
shogi for investigation) held in January of that year. I was Black and playing
against Tadahisa Maruyama (now 7-dan, and will certainly be an A-class player
next year). At our post mortem Aono 9-dan joined in. A while after the Minami-Aono
game just cited, Aono-sensei said to me, "Thanks to you and Maruyama-kun,
I managed to win. But, boy, was it tough!" It was only then that I
knew about this game.
You may well wonder how a crude suzume-zashi which didn't work as a Black
tactic can be effective as a White's trick. This is a good example to show
that sometimes in shogi it's better not to make a move. White's right G
stays on 5b, and that's where it functions better for the guard.
