KGF is the best way for the allies to have any chance of winning without any bid.
A good axis player will recognize this and start out stacking German defense right out of the gate:
10 inf rd1. Japan flies 2-4 ftrs into Africa, aiding the building of Fortress Europe.
So, in OOB rules with Tech and National Objectives, no bid, the best hope for the Allies is technology (that and good dice for you and bad dice for the axis). IMHO, the axis should never lose in this scenario, IF they were playing to win (vs trying new things)
If that doesn’t float your boat, try throwing too many units/targets at Germany and Italy early for them to handle. Personally I like a few Russia tanks over ftrs. They take and hold land, especially with some UK or USA air power to protect any Russian stacks from German counter attacks. At least this method can push the deadzone territories to East Poland/Ukraine/Karelia to keep Germany too close for an Italian can opener to enable a German tank blitz to hit Moscow.
Godzilla gets too big too quickly, and there’s not a whole hell of allot that the allies can do to slow that down. You might try and get all hopeful that an India complex is possible on UK1. Russia needs to move many units into Persia R1 to support that IC and then Japan needs to not be in any position to hit India J2 (or Australia for the matter) because US ftrs can go to aussie and then India USA 2, to help hold the Indian complex against a J3 attack
If Japan plays it right, she won’t allow the IC to be a realistic option for the allies.
