To Kuhan and Proteus, there is also a 3rd scenario. Often you need to Choose if you go for a war win or for acres and it can be different strategies for each(for example if u start off with disabling t/m threats or ignore them, who u chain, do u go for econ/FB, what drakes etc). If your opponent is good enough to realize that you are going for longer term, they will instead just make a tactical WD and you end up losing acres. And if you play for acres, who will be the actual loser then? Not that black and white.
