A page for 1-3-5 formations based on a 3-4 point. By now just about all the Chinese-like formations one would normally come up with have been tried as experiments in pro games.
There are many examples of possible Chinese-like formations. Assume in place: the other two stones can vary. This one was played by Kitani Minoru against Takagawa Kaku in 1959 (perhaps first seen when played by Doteki around 1680).
Moving the central stone one space to the left: this was tried several times by Ishida Yoshio.
This one is an experiment of Hikosaka Naoto in 2000. With the central stone at b: Miyamoto Yoshihisa in 1996 (see further discussion by Charles Matthews). At c: played by Hashimoto Shoji and Kato Masao. At d: Hashimoto Shoji, Abe Yoshiteru.
With the stone at g this was played by Ma Xiaochun in 1982.
The Manchurian fuseki pattern hasn't (yet) shown up in pro games.
