Here is my allied open vs a standard axis open. I call it the KIF (kill italy first)
US
Point is to treathen Italy from turn 1 and force germany to protect it, it is however very flexible, strong and can quickly adapt to kgf (d-day, norway). To get the required staying power against luftwaffe you need to borrow the z10 fleet to the atlantic and move it to z89 with US. Your US buy will be 3trannies,2sub and a carrier (or a dd if germany subs r a pain). The goal is to get all US/UK ground troops into action asap in europe and create a 2front war (all generals nightmare)
Round 2 you most probable have to go all pacific and continue that way during the rest of the game to prevent japan victory.
Russia/China
To pull this extreamly offencive europe move US needs russia’s help to prevent japan early India takeover. Send all soviet mec,tnk and air to kazakhstand r1. Combine them with china if needed r2 in Szechwan. That will make japan wet their pants because they cant hold yunnan nor treathen burma or szechwan with an airstrike. You might considder a offencive buy with russia to (like 3 mec, 4art and 3inf r1). Place mec in stalingrad. Dont worry much about germany as he still have to move his inf all the way to russia, and youll be back by then with your flexible fast moving units.
UK
UK build 9inf r1, kill italy fleet, then build big trannyfleet l8tr shielded by US, they leave the seafighting to unclesam :-). Dont loose egypt. Pacific they stack burma 100% and build 3inf 2mec (or just inf).
Anzac
Anzac is hard, but you can always box in as your goal is to prevent japan victory (being so strong in europe). I build tranny turn 1 to get the +5 NO turn 2, but thats up to you.
Remember flexibility, mobility and offencive moves is the key to KIF strat, force your oponent to respond to you, not vice versa. Get Axis of balance and watch them slowly die as you economic is far stronger.
Im not going to bother explaining the KIF any more, but if you check out the save file you will most likely understand how this strat work.
Note that it has 6bid to allies (sub med) and that is not usable against japan dow r1. And bid over 10 should give allies a small advantage by brit fgt in scotland that unbalance germany even more.
