Maybe try to let him take Caucasus :-P
withdraw almost all of your units from G in Caucasus to Moscow…
let him take Caucasus, and counter it with J instead!!!
then J has more IPC’s and can get more units to the front than G ever will.
G loses 4 IPC’s but gets 4 Japanese armor to help instead :-)
Why not withdraw all units, you say?
If you do that, he’ll see what your up to…
if you play a little poker, and make a calculation that will lose statistically…
he’ll see an opening because he thought you made a mistake!
leaving it wide open will make him suspicious.
