Last point.
I really love playing with the +1 soviet attack bonus(mild blizzard). It changes the mindset of the game for both of us in my opinion.
Instead of thinking "i'am doomed" let's mitigate the damage, i have tactical option to bite my ennemy and it make a game much more fun. I can think of limited counter attack.
The german also have to be carefull.
What is funny is when i performed some local counter attack, i discovered that in fact, the +1 bonus was not needed as my victory odds were better than > 2.0. So it was mostly a psychological help. But psychology change everything as i can try things that i would have considered too risky without it.
The +1 attack in an Expert hands for the Soviets is "ludacrous". I have played on both sides of the fence with the +1. But even if you don't have the +1 attack the attacks in the mid part of the board all the way south is always possible. You just have to set them up correctly.

Set them between the area the Russian player is attacking. I would also bring a couple of HQs back (like the RHQ or any extra HQ that you have) stack some AA in that HQ. Something like 6-10 AA units in each HQ and put one in Berlin and one in Madgeburg. Fire for effect
