You will read multiple ways probably in the threads to do G1. I don’t usually attack the BB, because in this version, the axis already have the advantage. The axis don’t necessarily need Africa, but it definitely helps. My G1 is usually 1SS, 5inf, 2art, 2tanks or 1SS, 1 Bomber, 6 inf, 1 art. Japan being uber aggressive on Asia is the key here along with killing the EUS fleet. It’s a CA vs SS, but the benefit is that the US is out of the Atlantic ASAP. The question on what to attack comes down to what did Russia leave you with? If Ukraine is dead, than your Egypt attack becomes a bit more hard (and if they decided to reinforce Egypt with a FTR).
Typical targets for me on G1 if Egypt looks out of reach: (I don’t have my board in front of me so it’s not uber specific)
Attack UK Med CA with BB
Attack EUS with SS
Hit the Russians back in Ukraine, take Karelia.
Make Norway inviting (use it to invade Karelia)
Disperse the Baltic fleet (spread them), fortify France with FTRs (ensure you get 1 back to Germany to protect from IB).
Hit the Med DD with a FTR/Bomber if you can spare them.
I like giving the Brits bait to attack multiple units.
If Egypt was not reinforced, and Ukraine lives, annihalate those Brits on G1 using Ukraine FTR and bomber with all possible land units. But ensure you use the SS to take out the EUS fleet (or at least try). Getting your planes to France along with buying a SS will help establish Atlantic dominance on G1.
There are other ways to do this like I said, but I like Japan doing the slaughtering with Germany establishing Atlantic dominance to conquer Russia.
