I've just finished (and won, but I think my opponent and me weren't really playing for a win any longer, but just to know where this thing will go) this game, on a 13x13 board.
You'll notice the game isn't starting as a crazy fighting game. Go to move 14 and try to imagine final territories. Then proceed.
We're both 7k OGS at the end of the game, I'm white. I hope you'll enjoy only half as much as I did
