Here are a few tips:
R1
Usually Russia attacks West Russia plus either Ukraine (3 inf 1 art, 2-3 arm, 2 ftrs) or Bielorussia. If you’re feeling lucky you might make Norway the target of your 2nd attack and prevent G from attack the UK BB.
The RUssian inf are usually better on Caucasus to move against any retake by G of Ukraine.
G1
Always retake Ukraine if the Russians have conquered it. You’re giving them 3 IPCs for free and not getting them yourself for a total of 6 IPC loss. You should be trading Ukr/Kar/Bielo with the Russians, even better if manage to be trading WRussia with them.
UK1
The attack on New Guinea is risky but it is also one of the best moves for that fleet. If it succeeds it takes 1 IPC away from J.
Another good attack, if Egypt has not fallen to G (and if you’re not building an IC on India, which I don’t advise), is to go against Borneo with the transport and 2 inf, with the cruiser providing bombardement. Fighter can land on the US carrier or stay on middle east to take care of G med fleet or take out lone J transport (or you can send also the AC or the cruiser against it - but sink it!)
J
The main targets are China, retaking Borneo if it has fallen and the US fleet off Hawaii, along with protecting any purchased transports.
