I'm sure all the while you keep asking for help on this forum people will be happy to offer good advice. Your technical ability will grow and soon it will be you handing out the ass kickings [:)]if someone more experienced with Soviet play would take me closer under their wing to teach me it would be great.
Even good Soviet players are walking the wire these days in 1941, and every mistake you make snowballs so that even small differences in skill level between opponents become magnified fairly quickly. That's one of the reasons why compleated games are quite rare.
I have to concede that this game is probably lost now. 4th pz group will be winging it's way towards Moscow as we speak and the Summer's only half over.
I would continue though. Go all in at Moscow, build a massive wall and force him to take the city. It's a common situation in this game and learning (possibly by mistake) the technical aspects of defending Moscow against a strong human player will almost certainly pay off in future.
When this game finishes please start another AAR and we will help you out where we can. Also read the AARs of successful Soviet players paying close attention to their tactical defensive setups. I think you have the right idea but it needs honing and like a chain your defense is only as strong as it's weakest link.
