|Section 2: Formation with black Rook on 2i|
Black aims at the 5th and/or 6th file, where White is less guarded because
of his bo-gin positioning. The idea was good, but the moves to realize it
were rather awkward and apparently vulnerable, reflecting the undeveloped
Moves after Diagram 1:( from White)
S-8d; P-6e S-7c; S-6f K-2b; G7h-7g
Those moves, S-6f through G7h-7g by Nakahara, caused a sensation at the
time. Some cited an old saying "There's no must for meijin" (meijin
ni joseki nashi=No joseki for meijin). Indeed the position after those moves
would have invited criticism, if it hadn't been made by meijin. But this
position became a big hit among top-class players.
One player who was benefited most by this formation would be Osamu Nakamura (now 8-dan), who won the shin-jin-oh crown (king of rookie players), and got himself the Osho title from Nakahara. The R-2i was his favorite formation, which presumably matched his own playing style.

Diagram 2 shows where Black placed his R on 2i in the Shin-jin-oh-sen
game between Nakamura(b) and Miyata(w), a prototype game, played on 31st
October, 1983. See for yourself how White opened fire only to fall prey
to Black's trap.
Moves after Diagram 2: (from White)
P-7e; N-2e,S-2d; P-6e,B-4b; Px7e,P-6d; Px6d,Sx6d; B-4f, P-5e; S-5g,Sx7e; P*7f,P-8f; Px8f,Sx8f; Bx5e,P*6d; Sx8f, Rx8f; P*8g,R-8b; P-4f,...
Against White's P-7e, Black countered with N-2e through P-6e. A few moves later Black played S-5g, Nakamura's finesse, which put S, laid up idle in suzume-zashi, onto the center field. While letting White take P on 8f by Sx8f, Black countered by Bx5e (if (w)R-9b, then (b)P*8d), followed by (b)P-4f, which made Black happy.
