You fight like a Russian! Your losses are painful, but not critical yet. The hardest time will be right after the mud, the November offensive; I often do my best work then, and take the steam out of those Blizzard offensives. Since he is not trying to cross the Oka, I would assume he will try to snap off the troopers you have north and west of Moscow. I wish I could give you better advice, but I tend to play as Axis most every game (even though I am an equal opportunist). Dig in as best as possible, and try to keep the flanks wide and deep. Oh, do the same in the other areas too. I would think though, keeping your armies intact at this stage of the game are most important, the cities you lose now you should be able to take back come December.
You have the making of a tremendous game here, this is balancing on the blade of a knife. Good luck, and may Providence smile upon you.
Very astute observations! The game is currently at turn 24, almost Blizzard, and you come quite close to predicting what has happened. Won't spoil the fun though, but it has been a real nail biter for me.
