One thing you can do as the Allies to throw a curve ball at the Japanese is to build a CV for the British on B1. On ANZAC 1, save at least 6 IPCs and lay down a CV on ANZAC2 in SZ62. If you move the US at start fleet to New Zealand on US2 from Pearl, and move the British fleet to SZ56 on B2, then the Japanese have a dilema on J3, as the US fleet in New Zealand, and whatever air the US may have in Australia, can counter-attack SZ56 from New Zealand. The ANZACers can follow up with a smaller, part two, counter-attack in their portion of the third turn as well, from SZ 62.
When the British make the move from SZ39 to SZ56, they can swap out their fighters for ANZACer fighters if they wish, leaving India strong.
J3 is generally the turn in which the Japanese will want to take Singapore to get ready for the major IC there on J4, and will have to face the fact that if they wish to take out the British fleet before it links up with the rest of the Allied CVs in SZ54, they’ll have to divert carrier air from the assault on Singapore to conduct an air assault on the British fleet. If the Japanese try to take on the British with Navy, the US and ANZACers are positioned to counter attack.
If the US buys a CV on US1, and it is at Pearl on US2, and Japanese let the British fleet go by on J3, then the Allies can put the British fleet, the ANZAC CV + DD in SZ62, the US fleet at New Zealand, and the US CV at Pearl all in SZ54 on turn 3.
The Allies will then have a strong defensive position in SZ54 to attack out of in later turns.
The main problem with this is that while a multinational fleet may be great on defense, it isn’t too terribly good on offense…at least until the US can pour more units into that SZ.
