The last point is the hardest one, and the rules make sure of it.

You are on 7 and they hold both battlefields. Try each line and see which ones actually end the game.
Remember
Each battlefield pays you at most once a turn, by conquering it or by holding it, never both. From 7, a conquer is only your last point if you have scored every battlefield that turn — and a hold earlier the same turn counts towards that; otherwise it draws you a card instead. So the 8th point comes from holding into your Beginning phase, from running the whole table in a single turn, or from a card effect. Conquering can happen on their turn too, so neither player is ever safe between turns — and reaching 8 only wins at a cleanup, with strictly more points than your opponent.
