I for one welcome our new surrounding your opponent on a 19x19 grid overlords.
I am reminded of a comment by Trevon Truran, developer of the Discworld game Thud - a loose equivalent of chess/go which recreates the Battle of Koom Valley, where the Trolls and Dwarfs each claim they were ambushed by the other side. It's based on the Icelandic (Nordic, anyway) game hnefatafl https://en.wikipedia.org/wiki/Tafl_games which is unusual for board games in that it is asymmetrical and a match involves playing two games, one as each side.
In an photo accompanying an early article about it, Trevor is shown staring intently at a game in progress and the caption is "At this point, the best move for the Trolls is to kick over the board and run away". Perhaps that's the best human move here.
