I agree with you on Bury. As Japan I’ll obliterate the Bury forces even if I have to let America keep her fighter in China to do it.
As Russia, however, I recommend keeping the fighters in Moscow from Turn 2 and beyond. (You may need them in Caucasus on Turn 1 to prevent a German amphibious assault of Caucasus.) England and America should be staging fighters in Caucasus to set up a sinking of the Bismark, IMHO.
Also, before Round 4, I highly recommend getting a third fighter for Russia. Makes strafing Kazakh, Novosibirsk and Evenki much easier, and less risky. If you plan on it from the start, you can save up 3 IPC a round and on Round 4 you’ll already have 90% of that 3rd fighter saved up already.
As for stacks, I like to stack W. Russia then Karelia. This allows England and America to reinforce and replace you slowely so you can move out and towards Japan. It also secures Norway preventing, forever, a German reclaimation project there. (I believe Russia needs Norway more then the other allies for income. It replaces SFE, Yak and Evenki.)
