OK you mentioned Allies at 9, so here are a couple bids I like at 9 ipcs
All Russia:
2 artillery, in Karelia and Caucasus, save 1 ipc.
For 25 ipcs Buy
Defensive
5 inf and 1 artillery and 1 tank
Offensive
Buy 3 inf 1 art and 2 tanks
Attack Ukraine heavy with 3 inf 3 tanks 2 art and 2 fighters
to strafe or take depending on the opening roll
Attack W. Russia with 9 inf 3 art 1 tank
Non com: AA guns forward to W Russia, or W. Russia and Ukraine depending on the results of the attack (strafe/or take, how many inf remaining etc.) Option move 1 Kazakh inf to szech for fighter defense. Option 5 stack to Bury. Or full western focus depending on the results of the attack.
Place: drop 3 inf 1 art in Caucasus, with tank(s) in Moscow. Additional infantry (if bought) option either Moscow or Karelia, depending on whether you want to draw a counter attack possibility or just let the germans walk in to escape bombardment.
I think that should set up a decent Russian opening. Another approach is 2 tanks to W. Russia, 2 to Ukraine, depending if you want to go lighter on Ukraine in case of the round 1 sweep.
All UK:
1 inf in Egypt, and 1 sub in sz 35
buys 3 tanks in India 1 fighter in UK. Option 1 inf in UK or save 3 ipcs
or
buys 3 tanks in India 1 bomber in UK saves 1 ipc
The extra infantry unit should be enough fodder to keep your Egypt fighter alive into the second round. The sub can join an attack “all in” on sz 37, or if you forego 37 it can peel off with a fighter to kill the Japanese transport in sz 61 landing either in Bury or Szech.
To set up full KJF, or Japan Stall, or tank support to Russia post India withdrawal
Split bid at 9:
6 to Russia, 3 to UK for
1 tank Russia, 1 inf in Egypt
The tank can be used to reinforce the attack on W. Russia, or brought in for the hit on Ukraine. I think it might be advantageous to have 1 tank over 2 infantry here, just to secure the counter attack options. But you could also try 2 inf for fodder in these attacks instead of 1 tank for the hammer.
The infantry for Egypt is, again, to keep the fighter alive into the second round. I think this fighter has the best chance of swinging the game, for early attack options or long term defense.
USA destroyer bid:
8 to USA, save 1 ipc for Russia to convert an inf to artillery in the first round buy.
The only bid that stands to make much difference for the Americans is the second destroyer in sz 11. Or possibly in sz 19 (by the cruiser off panama) if you prefer to kill subs on the counter attack, or push Germany to consider sz 10 instead of 11, for fear of this counter attack
Just some thoughts, nothing is full proof. I think the first round is a bit dicier for everyone on this board. There is probably no full proof conservative winning strategy for the Allies even with a bid at 9. Something has to give somewhere, but these are some options on a bid. Hopefully it helps
Perhaps some others here have opening bids they like?
