@Afrikakorps:
I just realized the strategic strength of Bryansk again, with just the traditional Russian force of artillery and infantry this is very strong. With mechanized infantry instead of normal one you actually cover all of Russia and only need two stacks: Novgorod + Bryansk. The Bryansk stack can also include some basic infantry as it is able to retreat directly into Moscow.
I am forming a theoretical framework that reduces the dynamics of the board into principles that guide the formation of strategies. I began writing an article on it, but I’m not sure when it will be finished. Here is an excerpt from what I’ve written that I think explains why your dual stack Russian defense isn’t a good idea.
"Still, to help focus the discussion, let us give words to these concepts:
The force principle: powers must have superior force to win engagements
The economy principle: powers must have superior resource production to obtain superior force
Notice that these principles balance each other - the focus of one is always the pursuit of the other. The Allies, with a superior economy, must try to obtain a force advantage, and the Axis, with superior force, must try to obtain an economic advantage. In the actual war, and in many previous iterations of Axis & Allies, the economy principle gave an advantage to the Allies because the Axis had to work to take territory while the Allies could bide their time and build up their force.
Now let us try to quantify this new, less intuitive principle that seems to give an edge to the Axis in the 1940 series of games:
The mobility principle: mobility allows powers to determine where engagements will occur
Mobility in the 1940 games, and especially in Global 1940 (which we will focus on from here forward), is the wild card. It trumps both economy and force. The choice of where to engage enables the power with superior mobility to select only those engagements where it will enjoy the greatest tactical advantage or those that will benefit it the most economically, meaning that mobility can translate either to force or economy."
The argument I make following these observations is that it’s better for the defending force to take two separate and equal positions that will almost, but not quite hold than one position that will definitely hold. One example of equal positions would be London and Moscow. You’d rather make Germany fight for whichever one he wants than pick one to save and let him walk in to the other. Another example would be over on the Pacific side. It’s better to push suicidal Allied stacks at Japan from all sides than to retreat and let him have territory.
The Russian dual stack defense is different, because they aren’t equal positions. Moscow is obviously more important. Defending less important territory will just make your opponent all the more eager to press for your capital.
