The fourth game of the 63th Oui Title series 7-game match, where Toyoshima 9-dan was challenging Fujii Oui was held at Isuien in Tokushima city on August 24th and 25th. Score was Toyoshima 9-dan one win. Fujii Oui two win.
The fourth game was supposed to be held at Wataya Besso in Ureshino city on August 15th and 16th. Because Toyoshima 9-dan tested positive for corona virus on August 13th, the fourth game was postponed on August 24th and 25th, which was supposed to be the fifth game.
Sente was Fujii Oui, Game form was Bishop Exchange Double Reclining silver.
Fuji Oui played new move at the opening game. He moved his king to 3th rank and formed castle. He put Bishop on 5th file to look for Toyoshima 9-dan`s move.
Toyoshima 9dan`s sealed move was chance-taking move(56 moves), which was pawn-head
silver. Fujii Oui was thinking about this for about one hour.
Fujii Oui was better situation balance at the end game, but position was very difficult.
Toyoshima 9-dan was prepared for lots of traps. If Fujii Oui had made one mistake, AI evaluation would have changed. He sacrificed silver and approached Toyoshima 9-dan`s king vividly.
Fujii Oui won with 95 moves. If he wins next game, He will win Oui Title Series for three consecutive years. Next game will be held on September 5th and 6th.
I am looking for next game.
