So I might propose that sending units to Pskov/Leningrad while leaving the center and South to a random defense can spell disaster .. a defense not for the faint of heart ..
Aye, not for the faint of heart. But again my basis is to hold Leningrad at the cost of Moscow. Also there is defense in the South just not up close and personal with the Germans but more of keeping Germans on a supply leash. It all boils down to who, what, where, when, and how. Who I am playing, what I will do, where I will defend, when I will defend, and how I will do it. All those variables make for an interesting game and this is just a guide to either use parts and pieces or not use of your own accord. After the fact of having seen this it is "much" easier to pull the defense apart. (Joe Billings quote on his signature comes to mind, "All understanding comes after the fact" quoted by Soren Kierkegaard ;-) When it was first encountered many would just slip to the east towards Moscow.
