Here is what I have tried and it seems to have worked well against a friend of mine who is a very good Axis player. I have yet to ever be the Axis so I have some moves here that work well with using the 12 bucks at the start.
RUSSIA - 4 infantry in Bessarbia, or 4 infantry in Iraq
Why - 4 infantry in bessarabia help defend the one tank and artillery, and a first move attack by the germans there is almost none existent. The 4 infantry in Iraq is good because you can spare them and use them to help protect the oil.
Britian - destroyer in davis strait, or 2 Inf. on Malta and 2 in trans-jordan,
Us- gets $2 bucks from inital 12 and builds an aircraft carrier and a battleship with all its money (42)
