Good thread here, gentlemen. Many solid posts.
I’ll add a couple of thoughts. I have to admit, however, that I don’t feel particularly well qualified to talk about this topic because I am almost exclussively a FTF player. FTF games are functionally time-limited, and you don’t get many games where capitals fall and the game continues for many more rounds. Usually, good sportsmanship dictactes that after 4-6 hours you make your best guess on the winner and everyone heads to Chipotle’s ;) Online you don’t have the same rules-based or pragmatically-based limits.
On the rare occassions I have worried about countering Allied advantage, my response has been to go with a strong economic Japan game. R1 I’ll build Japan up to 4 transports, and then send them away on cash grabs. ICs go up on the mainland, but they build only inf until A) you have 4 of them and B) you can build 6inf on the 2 forward ICs (IND/MAN) and 6tnk on the interior ICs (FRI/KWA).
The econ transport progression is this: R2 2tra to HAW. This nets +1 IPC and forces some consideration to defending LA. That slows the US a small amount. 2tra more go to Frindo. R3 the HAW 2tra take AUS and NwZ. The Frindo 2tra hit some combination of Africa, often MAD and then wherever the Allies aren’t. R4 you keep living the life of a pirate. The African tra either scoop more land or come back to Frindo to help with a shuck. The AUS/NwZ tra move east, looking for BRA/Africa on the following round. Notice that you’ve set up the Z42 sucker punch which can win some games for you (see CSub paper for that move).
On the mainland, you’ll have avoided a “tank bubble” and instead you’ll have solid columns of inf marching up with no land-swapping at all. The buildup is slower, but what Japan takes, Japan keeps. When the end comes for Russia, the flowing power base is significant.
Now in a 5 or 6 rd game, that strat is not going to pay divedends quickly enough. That’s what I was developing in a longer format, however, and it is the next strategy I would attempt to refine for the longer games.
Have at it!
