Obviously this is a niche strategy, but there could be some use for it - it may allow the Allies to take one of the money islands as soon as US3. Here’s the plan
Unite Pac fleets in sz 30, build IC Aus
Attacking sz 30 is very risky for Japan, and it forces Japan to either to do Pearl light (with more risk of an unfavourable outcome) or skip Pearl altogether.
If Japan does not hit sz 30, build AC, fig, sub, trn on US1.
Move sz 30 fleet to sz 40, build AC sz 40
This threatens a unification of the UK/US fleets in sz 45 on US2/UK3. This combined fleet would consist of BB, 3 AC, 5 fig, 2 sub, 2 DD, 3 trn. This is too much for Japan to take on. If you add the 6th fig on US3/UK4 (and perhaps a UK sub that you build on UK3), you can take Bor or EI on these turns. Your combined Allied fleet would be so large that Japan has to bring something along the lines of 2 BB, 2 AC, 6 fig, bomber, DD, 5 trn, 4 sub to have a good shot at it, which requires a serious investment in the first few turns.
Without the UK IC, you would not have the extra UK carrier - a loaded carrier can make a big difference, and it may save you one turn in bringing down the Japanese in the Pacific. Of course, it comes at a substantial cost against Germany - that’s why it’s not played in most games, but it’s worth a try perhaps.
Japan can try to thwart your unification by moving its fleet to sz 45 itself on J2. I’d have to double check whether that is a worthwhile strategy.
