Not Go maybe Gomoku, the circles on the board that aren’t colored seem anomalous though, must be from a book on strategy showing potential moves. Anyway it’s posted by a mental patient so pretty much irrelevant outside his own brainlet.
Gomoku, also called Five in a Row, is an abstract strategy board game. It is traditionally played with Go pieces (black and white stones) on a Go board. It can be played using the 15×15 board[1] or the 19×19 board.[2] Because pieces are typically not moved or removed from the board, Gomoku may also be played as a paper-and-pencil game. The game is known in several countries under different names.
