Building AC + 2 destroyers in SZ8 landing 2 US fighters and adding the US cruiser is usually a nice option if Germany attacked SZ2 and killed the battleship (if not, just building what you would need to survive an air+sub attack and build transports if you have money left. Depending on the German odds of attack on SZ8 you bring or not the US transports, and you may sent the UK transports on Washington’s coast not to lose extra units without reason against likely German attack. Even if Germany as better odds to win on SZ8 (depending on how many planes survived/were built), this strat is nice to lure Germany forces away from Russia and you should always be willing early to trade more UK IPC for a bit less Germany IPC (their “real” value is not the same since Russia/Germany front is ALWAYS the most important front). Also, if Germany had a very good turn 1 and kept all planes, you should be willing to take some risks to try to take the advantage out of axis’ hands.
Also it depends on how Germany places is units, if all planes are in Paris, you can build in SZ2 for exemple.
