Well, I have experimented some with this opening. I find that against a human, it works most times. Combat can be pretty random. Take that Russian Infantry div that is at the top of 6th Army at start, 6 out of 10 times I can knock him back with 3 div and then 1 can keep knocking him back. This time, it took 2 3 div deliberate attacks to move him away from the border.
I really have no problems with the armor units, The blocking Div that is whole on the west side can shoot due east, the other split units can re-combine and shoot where ever you want. Those units all die turn 2 anyway. Turn 2 against a human, depending on what he does, I shift that Corp back up towards Minsk on the North side of the swamp. Just depends.
You have seen my vs AI moves, but against a human, I will not risk my units driving too deep turn 1.
I was just showing that on turn 1, you can bag more units on turn 2.
