Shogi Game 4 (professional, some annotation by amateurs)
The following analysis is written by David Murphy (2-dan) and appeared in
"Shoten", the magazine of the British Shogi Federation, in January 1990. The
game is the 4-th of the five games final match of the 37-th Oza tournament.
It was played on 5-th October 1989 and time limits were 5 hours. The black
player was introduced in Shogi Game 3. Aono Teruichi, who has white, wrote
two very good bi-lingual books (in English and Japanese), which are still
available from The Shogi Association in England. After losing this game
Aono also lost the 5-th which signaled the end of his first title challenge.

(A) According to Mr Ito (a strong 5-dan amateur, living in London), if
21. ... Gx3c or Bx3c then 22.P'3d, 23.N'3c and 24 N2a+.
(B) Nakahara is famous for his skilful knight moves.
(C) After 93 minutes reflection!
(D) The start of a decisive attack on the 3d king!
(E) If 31. ... +Rx9i 32.N6e naturally.
Then if 32. ... +R9g 33.P'4d K4b 34.N3d and 35.Nx5c+,
or 32. ... +Rx7i 33.Kx7i Px8f 34.R'4d K3c 35.N'2e mates.
This is my reading of it anyway, not "official" analysis!
(F) According to Steve Cain (2-dan), if 37. ... +R5d 38.+Bx5d Px5d
39.R'3a decides. E.g. 39. ... S'4a 40.N'5c, or 39. ... K6b
40.Gx4f and 41.B'7a mate.
