Seems (and is) a very basic question, but kinda at the core of the game.
At one time, you will have to face directly a superpower that have high quality troops that significantly outnumber yours, merc or not merc, ideas or not ideas, they simply have twice or thrice the number of your soldiers. And there is no trick this time : no ally to make a diversion, no island or straits to trap stacks, nothing. It's an all out slugfest.
As I never got the grasp on how wiping (and not merely repelling) ennemies with any reliability, my tactic since the very early game remain the same.
A)Create a continous line of fortresses (sometimes, two contiguous provinces will be bessieged, allowing a small window to defeat one stack becore the other stack backtrack and reach the relief force. Tend to not work very well against Ottomans or France, since they have enough troops to bessiege both provinces and reinforce both with 50-100-150k troops. This however make sure that a single fortress falling does not mean the defence collapsing at onc (each taken fortress is bessieged ASAP and stormed, with a minimal cost if done quickly)
B)Choose an objective that will be ''heldable'' for a while (in the ''no trick'' scenario depicted above, it's going to be a fortress on my border than can will be stormed on day one of the war)
C)Play for 5 years a whack-a-moke game : ennemy bessiege your fortress, wait till a breach is made, counterattack, withdraw to zero attrition, repeat while attempting to blockade the coasts
D)Make the ennemy allies sign white peace
E)When you have maximum war score and the ennemy is war exhausted, counter-attack (if possible, reach the ennemy capital, if not just take fortress a bit deeper in their lands)
