On the usual go board, intersections are not equal: when you place a stone, it can have four liberties, three (on the side) or two (in the corner).

Have you ever thought of a go board, on which all the intersections would have four liberties? Nikola Tsarigradski has created such a board - it has a shape of a torus (or simply a donut).

In the August edition of the European Go Journal, we will publish Nikola's article on his research.

Nice board!

You can play this e. g. at the variant go server (https://go.kahv.io/), where it's called »toroidal go«.
