Yes, I do this now.
I haven’t lost, but I haven’t exactly faced opponents of the most maximum calibre possible.
If this was the position of my enemy, and I was the Germans, I would avoid the ensuing battle, and force the russians into positions where they attack me.
Force the bulk of your troops through the south, and hold UKRAINE, trickle in maybe 4 units a turn through transports/leningrad factory. Keep fighting toward breaking through the caucusus/middleeast with italy. Use your navy and airforce to buy time against Britan/US.
If the Russians stick with the holding pattern, you SHOULD be able to balance the game out in your favour economically, and NOW the onus is on them to beat you where YOU choose to fight.
