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. Pieter Stouten 21-th May 1990.
