I organized the incoherent mess into a logical strategy at the first page, I hope it is a bit more clear now. I included the Yunnan issue.
Arthur the Imperial Fleet can kill blockers in J3, while the Philippines fleet can also hunt ANZAC ships in J2 already to clear the way for a J4 invasion. Thanks again for the feedback though as it keeps me sharp and improves the strategy!
EDIT: Sorry another random observation, but this might be game changing!
I did make another observation while thinking about a solution for the Yunnan Fortification though as it means UK has just lost 2 infantry to the defense of India. If my calculations are correct India can muster the following force in the defense of Calcutta
14 Infantry, 2 Fighters, 1 Tactical Bombers, 2 AA (2 Infantry less when he fortified Yunnan)
While I can attack it in J3 with the following troops
6 Transports: 1 Tank, 5 Artillery, 6 Infantry, 8 Fighters, 6 Tactical Bombers, 2 Bombers with the Battleship and Carrier from the Philippines attack to defend the transports. This results into a big victory for the Japanese. This means I can crush India in J3 even while doing a Pearl Harbour attack. Do I miss something?
I further have 1 cruiser, 2 destroyers and 1 submarine near India in case nothing died by the defending USA submarine and destroyer in my J1 attack and if UK did not attack my cruiser and destroyer in UK1.
This leads to the conclusion that a naval base in FIC J2 is always a great investment as those 3 build transports can do a J3 India Crush or still do J4 Sydney crush dependent on the situation. Therefore J2 buy will change into 1 minor, 1 naval, 1 transport, 1 artillery, 1 artillery.
In case I can indeed do an India Crush, I could do a Sydney crush in J5, a whole turn earlier! Ofcourse a lot of land troops have died against India, so it is going to cost of lot of air, but in case it is the winning VC, what does it matter? I do have to take Western Australia here in J3 though so 1 less transport doing India Crush. I could attack Sydney with
Surviving India Troops (1 tank, 2 artillery) + full transport from Western Australia and J2 buy so 1 tank, 4 artillery, 1 infantry. All airforce, so 2 bombers, 9 fighters, 8 tactical bombers and bombardment of two Battleship and a Cruiser. This gives 94% chance to victory!
Then USA needs to liberate a VC in USA5 or the Axis win.
