You could also bid a factory if that’s what you think is a priority.
This is true but I assumed that a bid must be spent on units and not factories. Plus I still think it is best to save the money until you know what Germany is going to do. I mean if I place a factory on Egypt with the bid I feel like that is just asking for a sea lion feint while Italy bull rushes Egypt.
I mean it is no secret that the allies are generally being reactive instead of proactive early. I am having a hard time seeing why giving your self the most flexibility is a bad thing. It seems to be well established that the bid is best given to UK. As far as I see it UK has 3 objectives that it should focus on early. The first and most important is preventing sea lion. The next would be protecting Egypt and finally the last would be establishing dominance in Med. You could argue about whether the last two should be flipped but both are important. At the start of the game it is not clear how much focus each objective needs. However, after the first round it becomes much easier to guess how much will need to be spent for each objective and once they are completed UK can now focus on getting troops on Eurasia.
I know that with a bid of 20+ you can give your self good odds to attack Ethiopia , Tobruk and Taranto but 2 of those three battles need to go in your favor otherwise it spells disaster and that to me is a bad risk to take unless I have 90% plus odds. The benefit of this plan is its flexibility and that it allows you to maximize the use of the bid. I mean that 12 IPC saved could be either 4 extra inf on London round 2 or an extra factory on Persia/Egypt and you will not know what is a better to have at the start of the game but you will know by the end of round 2.
