not sure of the optimal german navy movements in conjunction with the Bomber buy
move the baltic out? just sit in sz5 and say: "Come close and I will whack ya"?
I think you should run the navy the hell away. It probably isn't going to survive, but it forces the UK to do something about it right there before it escapes. If they send all airforce then just hope that you burn off a couple fighters, if they send more than think about whether you can submerge your subs and come back with a big whooping, or if not then shrug it off and hope you take out 1 tran or 1 fighter.
If you can combine the baltic with the SZ8 sub then all the better, but you might not be able to if you like to take Anglo hard, in which case you need the SZ8 to kill the UK BB with.
But having the Baltic sit there has its own merit because you can use it for a couple turns to shuffle infantry from Norway/Karelia/Germany.
How about the MEd fleet? SZ13 is nice, saves a sub, pressures an Allied torch landing as well as SZ8.
This just depends on your game theory. If you like to take Anglo hard, then you'll just have to eat the cost of the SZ8 sub. If you can take Anglo hard it becomes hairy for the Allies because now they have to deflect at least 2 full rounds of units to try to dislodge the Germans, and personally as Germany I love to see the Allies shoving massive units down there just for preventative measures; that's a lot of troops I'm not facing in Europe.
If you don't really care to take Anglo hard, then SZ13 is what I like to do. It stops the Allies from jumping into Algeria on round one, and if it doesn't look like the Allies know what they're doing then I turn it into a naval link. You gotta annoy the Allies in some way whether it's overpowering Anglo or making a big fleet for low cost.
Do you just get 8 inf with the bomber buy?
Yup there's no other option. After that I'd just mash out infantry until armageddon pretty much. The only time I would stop infantry is after I have about 20 in W. Europe, 15 or so in Germany, 30'ish in E. Europe, and then I would work in 2-3 arm to push with.
