@Cornwallis if the Allies don’t have a major bid in the Pacific theater, J1 is standard. It gives such a huge advantage to be able to take islands before the Americans have any support in the region. In most League OOB matches with 50+ PU bids, the Allies will get an extra inf in Yunnan plus two more Russian fighters that provide enough support to hold that territory on J1. Sometimes the Allies can stack Yunnan with so many forces it can be retained even on J2. Hence, strategies are shifting to delay Japanese declaration of war until later in the game.
The United States need enough fleet so that the combined navy can sit off the coast of Australia without fear of being sunk, and have a potential move towards the coast of Japan to prevent that Axis power from crushing India for an extra few turns.
