To all the guys who say you don’t need a bid, I think its a lot different playing online versus face to face. Online players typically use an odds calculator before every little battle so things are very tight. The consensus seems to be that a bid somewhere between $10-20 is needed. The very best “E” ranked players strongly prefer to play axis and bids are higher. If there were no odds calculators being used and people were just going on their gut from experience or crude low luck estimates in their heads, the need for an allied bid would vanish amid that variability. I don’t mean this to say face to face players are sloppy players; its a lot harder to think and decide on the spot without a computer to guide you. But its just not humanly possible to tune every battle (including battles planned several rounds ahead) with that kind of precision in a face to face game. There is too much variability for a few units here or there to matter much, but in online games every unit on the board has a job to do every turn and for the next several turns. The only margin for error comes from dice, and under those conditions a bid is definitely needed to even it up. The setup for second edition came out of a ton of testing in the alpha era and its very well balanced, but only when played face to face without odds calculators.
The scotland fighter + 98 sub is a strong placement for a $16 bid, but although I haven’t tried it yet I am thinking the carrier thing will more strongly shift things in allied favour (and if an expert like wheatbeer is willing to try it, then I know its a good idea).
As for Russian builds, I have seen people build a bunch of infantry. Its not as effective as things for UK in the med because it doesn’t take the initiative away from the axis in the early rounds. G1 attacks are super fun and if done correctly they can bring down the USSR in a hurry but you probably never get Cairo if you go that route.
As for piling a bunch of infantry in Yunnan, Cow pointed out long ago that would be a game breaker so it is usually agreed that you can only place 1 unit per territory or sea zone that you already occupy.
