As you know Nc, I’m a fan of the Japanese, and I still contend that they are the key to the game, not Russia. Maybe I should redefine that to be the key to the game is the interplay of Russia and Japan - but I still think that Japan holds the power from the start since they are positioned as an aggressor. If I were playing Russia, I know Japan’s potential, as well as its weaknesses.
To take your strategy, which I like in my first impression, there are two things I’d look at:
1. Let’s assume that UK and US help in holding Karelia, and blunt the German advance in general (as you stated). If this is the case, I’d also assume some of the pressure intended for Japan is being redirected by UK and US. Perhaps not, but I will go with this. I would think it appropriate to redistribute pressure elsewhere to make up for it - so I like the idea of sending tanks to SE Asia by Russia. In fact, I usually buy a tank or two from the start to do so. This all falls under one of my perceptions of the game. There’s a revolving pressure that occurs between the Axis and Allies. Consider the positioning of the forces (A = Allied, X = Axis):
A A X A X
You have nations sandwiched between enemies, and as you go around to everybody’s turns, you see that coordinated attacks generally produce the best results. If Germany attacked only UK, then Russia would be free to waltz into Europe, and vice-versa. So I think as pressure is removed from Japan, it needs to be added elsewhere.
2. The tanks work better at assaulting than defending, so send them on to attack. If you’re not planning to attack Germany immediately, atleast move them back to Russia. This allows for counter attacks on Karelia, or moving on to SE Asia.
Those are my basic concepts for your strategy, so I agree with it so far. It may only be 2-3 tanks, but in the Pacific theater, that can make a big difference.
Other reasons why I’d go for it: There are limited Allied units in SE Asia, so any extra defence is welcomed. If you can reduce/stagnate Japan’s income, then by all means do so (with a meager 25 IPCs to start, removing any mainland Asian territories is a big strike against them). Holding Russia’s backdoor is essential in their survival, so buying time and relieving pressure can help deal with Germany. Forcing Japan to reacquire beachheads will relieve pressure from the US (transfer of units from Pacific to Asian coast). Holding or increasing Russia’s IPCs will help in the long run, and help to produce more units for either front.
