DragonKing: I think that any game ought to be resigned in a hopeless position. But not everyone thinks so. There are people here that will drag out a game for an extra half year, even if the outcome is known. (And I'm not talking about Tank Battle in particular).
DragonKing: You don't score for the tanks you capture. You score for the tanks you have - with bonus points if they are in the enemy starting area.
Since you have 9 tanks, none of them in your opponents starting area, you have 9 points. Your opponent has 11 tanks, none of them in your starting area, and hence your opponent has 11 points.
And next time, please make your game number a link.
