For whatever it is worth, I think he is running too fast in the south. IMO, the Soviet can and should hold the Dnepr until turn 6, and then leave behind a screen of pickets to slow down the infantry. This screen will die, but buy time. The danger here is that your infantry will arrive at the Donbas with plenty of clear weather remaining, and if you can threaten that, Tula, and Moscow at the same time, rail cap simply will not keep up. Every one of those takes several turns to evacuate. He's not doing anything to slow the landsers down, and you're absolutely doing the right thing in clearing a broad front for them to advance quickly.
You don't need to save everything. Indeed, it's in the Soviet advantage to get a lot of stuff killed, including the tank divisions. They are armament and vehicle hogs, and I will cheerfully use them to screen the infantry so it can withdraw.
