Widest Path / 1975 to 1977

Sub-page of WidestPath

Below is the widest path (found by following the most popular response to the most popular move... etc.) for the three years 1975 through 1977 as they are represented in GoGoDCD. --DaveSigaty

[Diagram]
1975 - 1977 moves 1-8  
  • Black 1 - 268 games; B wins 57.8%, White wins 41.7%. This is the first period in which B 1 on hoshi was more popular than the komoku play at a.
  • White 2 - 92 games; B 52.1%, W 47.8%. The komoku play at 4 and the san san at b were nearly as popular with 82 and 69 games respectively.
  • Black 3 - 54 games; B 50.0%, W 50.0%.
  • White 4 - 26 games; B 46.1%, W 53.8%.
  • Black 5 - 10 games; B 50.0%, W 50.0%. The alternative play of 5 at 7 was almost as popular with 9 games. The high play at c was used in six other games so overall the Chinese Fuseki in one form or another was chosen in over half the games.
  • White 6 - 4 games; B 50.0%, W 50.0%.
  • Black 7 - 4 games; B 50.0%, W 50.0%.
  • White 8 - 2 games; B 50.0%, W 50.0%.

That's all! Black tried each of d and e so the "Widest Path" had reduced to a single game after only 8 plays in this period.


Here the sequence according to MasterGo:

[Diagram]
1975 - 1977 moves 1-8  

Black 1 - 276 games, black wins 60% (total winning percentage for black is 56%)

White 2 - 121 games, black wins 59%. Here more clearly ahead than with GoGod - the komoku scores 77, san-san 51

Black 3 - 77 games, black wins 58%.

Black 4 - 25 games, black wins 60%. san san at a scores 24, hoshi at c scores 17.

Black 5 - 10 games, black wins 50%. Both the high Chinese at c and the kakari at 7 score 8 games.

White 6 - 3 games, black wins 33%. The two game collections differ here - GoGoD gives d. MasterGo gives 3 games for e as well, but I chose white 6 here, because d is similar, while e has no similar move (the only remaining one is 7).

Black 7 - 2 games, black wins 50%. The "widest path" goes to one move after this, Ando Akio playing f against Ogoshi Ichiro, while Otake Hideo plays g against Kobayashi Koichi.
