As an example of shagami-yagura, I will show you another Nakahara(b)-Yonenaga(w)
game, which was played on 29 & 30 March, 1979.

See how the White's king is castled. This is called shagami-yagura, or
kikusui-yagura, or Takashima-yagura, and appeared many times in Nakahara-Yonenaga
matches, demonstrating how tough it was. Though it is rarely seen these
days, this formation can be quite successful in the sense that it allows
his own king enough space to avoid fatal threats. Only, you've got to be
very careful when you are about to form shagami- yagura, especially the
timing of N move. It can be vulnerable, when the N leaping is taken as a
cue for an attack. Look at the example below. It was taken from the fifth
game of Meijin-sen, played by Habu(b) and Yonenaga(w), on May 30 & 31,
1994.
