A fan asked Your Bored Brother for his Diplomacy map files, and suggested that I make them accessible on my blog. So here they are!
Blank Maps
I have used these maps before to draw diagrams and make other maps. I’ll admit that they are extremely simple…but they get the job done. These are modified from the webDiplomacy map so that you can use a “paint can” tool in a basic image editor to change the colors.

Solo Win Maps
These are the maps you’ll find the individual Gunboat Solo Win guide pages.
All Northern centers, plus Tunis, Moscow, or Warsaw. 
Usually, all Northern centers plus Tunis. Once in a while, Italian home centers will work. 
Getting to 16 is not so hard, but reaching 17 and then 18 is difficult for Germany. 
Austria has the narrowest path to victory of all 7 powers. Almost always, Austria needs the Southern centers plus Munich. 
Turkey’s “A” plan is to take over the entire south plus Munich. But if Turkey allies Russia (“Juggernaut”), Turkey can sometimes win by taking over the Mediterranean. 
Italy is special among the 3 Southern powers: once in a blue moon, Italy can advance far into the North. 
Russia’s path to victory is completely different from any other power. Russia needs to advance far into both the North and South to win.
North and South Maps
The mirrored powered are France/Italy, England/Turkey, and Germany/Austria. Russia straddles the traditional North-South stalemate line.
