Sofia Fuseki

    Keywords: Opening

bugcat: I get the impression that [ext] Sofia uses this opening pretty often in her games on OGS, which are somewhere around the 2k-2d level.

It's a highly influential three move fuseki for Black, which doesn't try to take any immediate corner territory. That said, since White only has time to take three corners, Black will have the right to claim the fourth if she wants.

The opening is made up of a 6-7 point, an 8-5 and a 9-4. The stones snuggle into a relatively small area of 5 x 11.

AI (the OGS bot) says it loses about five points if White plays three komoku. Of course, a point evaluation doesn't mean much when the board is so imbalanced. [1]

Sofia fuseki, or "Sofuseki"  

It's a little reminiscent of the experimental fuseki of Chinese professional Gan Siyang. Also of the Great Wall.

[1] To use the chess sense of positional imbalance as a focus on heterogeneity (difference) rather than inequality. That is to say, the position is novel and unstable.
