Good stuff guys
Two I’ll add:
Anzac fighters can reach Brazil from New Zealand in one turn, as can newly purchased bombers. If Japan puts its early focus on the mainland, Anzac can really support the Atlantic theater (by the end of its third turn Anzac could realistically have 2 bombers in Brazil and 3 fighters in the Med).
On the other hand, sometimes Japan will hang in SZ6 or Caroline Islands for a turn. In that case, you can actually ensure that china holds onto Yunan for a turn, therefore letting them buy artillery. Let’s say Japan doesn’t stack its entire air force in Kwangsi on J1. What I’ll do sometimes:
China attacks Yunan with everything, places its 4 infantry there. India declares war on their turn and brings the two Burma infantry plus its 3 planes into Yunan. On Russia’s second turn, they bring a mech, tank and 4 planes into Yunan (the mech and tank in Stalingrad I always move toward Yunan turn 1 and I buy a fighter as well). By J2, Yunan can be guarded with something like 13 inf, a tank and 7 planes. Unless Japan has its entire air force within striking distance they will not be able to take Yunan back on turn two, allowing China to purchase artillery.
