Long time go player here - this is really cool!
I only played a little, but it is clear that this game strongly prefers tight extending connections. In go terms “territory.” I am not clear if ‘influence’ is as useful a concept here; it seems very strong to make tight connections.
One of the many things that make go great is that a range of moves in relation to other stones provide a set of trade offs - more certain connection but less total influence / future territory ‘claimed’ - I’m not clear your variant has this. If so, it would be really useful to explore these move sets and give the player some basic tutorials about them. If it doesn’t, then I humbly suggest you change the rules so that it does. Perhaps tight groups can extend their ‘non placement’ range a little more, or extend their distance at which they connect up to a lone stone?
Last note, any beginner go tutorial explains that it costs more stones to live in the middle than it does the side, and that costs more than the corner. I’d be super interested to see some minimal living group definitions in the tutorial.
Again, thanks! this is really cool.
