Anyone have ideas? I left this open so people could format their response for any country they want. Should I give a more specific scenario?
But here's my thoughts on it. When you're at 8 SC's and are the largest power on the board, you have a big target painted on your back, so what I suggest to do is wait. You're not strong enough to make a solo bid, so aggressively pushing forward would just solidify a front against you. Therefore, it makes sense to bide your time, and help other countries around you gain centers, keeping your neighbors in conflict against each other whilst making sure the east or the west doesn't solidify into a single power or single alliance.
This is one thing that I don't believe enough people grasp. Your actions influence every other member on the board, no matter how far. If Turkey attacks Russia, that draws Russia's forces south, perhaps sparing England and Germany from losing Scandinavia. If England moves a fleet to NAO or Irish, then France will have to pull a fleet out of the Med and there's one less unit to pressure Italy. As the largest power on the board with most of the nations alive you can quite literally shape the board how you want to with just unit movements. Add press into the matter, and that simply amplifies the affect.
Back to the matter though, my strategy would be to keep my neighbors at conflict with each other. So if I was England, I'd try to keep G and F fighting, if Russia, then keep I and T fighting, etc. The stab would have to be swift and decisive, earning me 3 builds, two at the least. The jump from 8 SC's to 11 SC's is a large one, and the momentum from such a jump would be enough to carry a player straight through the stalemate line, before the opposition can realize how much of a threat you are.
If there's one thing that I've learned best, is that the merits of placing a unit beyond the stalemate line are decisive. As Turkey or as England, I will always try to slip fleets through MAO, and they pay more than enough in dividends to compensate for the lack of territorial gains.
