Cool. Three 10's can claim, since Orange 3 is played already. A cosmetic (but useful and sound thematically) rule I change with this game is to put the claimed stones on the losing hand. It serves as a reminder that you can't play there and aren't we fighting for borders? We want the borders to be far from us, not closer to us. Right?
Indeed, this was not a "real" game, I just (too, apparently) quickly laid down the pieces for the picture, missed that orange III...
I agree with your cosmetic change, I was thinking of playing this way specially with this wooden version, since the "flags" are pieces of the battle line with the 3 tiles facing each other on them, you will see how your line is pushing the other army.
