|Opening moves of the game (the only picture I took)|
1) A draw goes to the defender.
2) Overtime - carry on playing for a set number of turns then see if the points are still drawn.
3) Golden point - keep playing unit one side gains the next terrain feature (points).
I thought option 1 to be unsatisfactory. So the question was option 2 or 3? I went with option 3 (golden point) with the game being played using dusk and night rules.
With the new campaign rule, the game went for another three turns until Commonwealth infantry reserves finally moved up and were able to occupy the buildings. These buildings had been contested for most of the game.
