Sov bulge NW of Moscow: there is a gap (FOW off?) in the Sovs frontline which I consider a rare opportunity to start a pocket. March is snow weather, and your Pz/Mot Divs will be back to business. From your pictures you have a rested and refitted(?) 3rd Panzer in Moscow ("southern pincer") and lot of IDs north of the bulge ("northern pincer"). At leat I would go for it.
Thanks again for your elaborate comments.
