I have but one big question:
What does this do that you can’t also do with a J1 attack the same or better?
Japan trades with America, for +10, but at the expense of not slamming the hell out of UK Pac. It’s also not getting 2+4+3+2 = 11 IPCs from FIC/Borneo/Kwangtung/Philippines, so you’ve really managed to actually cost yourself an IPC, not gain any. You’ve also delayed your possibility of putting a mIC facility in FIC by an entire turn (and therefore any new units wait until J4 to be useful). I know you said you don’t build mIC, but that’s a whole other subject. You also can’t build a naval base there J2, meaning using it to threaten SZ 6/Carlines must wait until J4.
UK Pac gets one whole extra round of full income, including their 5 bonus (edit-actually, do they get this if not at war?). They could take a money island/Dutch New Guinea (I say could because I usually use the UK Pac TT to take Iraq UK1 and their transport gets to live until the next round for a continued botherance). UK Pac gets to keep their battleship, which, while very possibly is not useful in the pacific all that much, can be in the med 3 turns later and is useful there, or it can suicide into some JP fleet later with the other boats, or a crafty UK player might keep it alive long enough to stack with with the US/ANZAC invasion force.
ANZAC can grab a money island/Dutch New Guinea, just like in a J1 so no difference, but since you’re not at war they don’t make their extra 10 IPCs on round 1. This might make up for the gift you’ve given to the UK, because I’d argue that I’d rather see the UK Pac make money, and ANZAC not, since UK Pac is easier to shut down and can’t meet up to reinforce the Americans the way ANZAC can. So here, the situation with ANZAC, is the first piece (and only), that I can see working a bit better than a J1.
And as for the US, at the start of US1 they’re going to have 52 IPCs either way, war or no war. They can also move their fleet basically anywhere they like to position it. All you’ve done to the US is delayed them from getting 30 IPCs on US2, but those 30 IPCs wouldn’t have been a threat that you had to consider, at the earliest, until J4. But you’re potentially not even doing that, costing them 30, because you allowed 26 IPCs (fighter/sub/DD/2 IPC) from the Philippines to live. You may very well kill the two US boats on J2, mind you, but a crafty US player can scatter them or send them the long way to Hawaii to make doing so absolutely unappealing.
Is the bomber purchase only to be able to bomb Calcutta on J3? I don’t understand why you’d need it on J1, so early, otherwise.
China is in basically the same position as it would be in a J1 attack, maybe slightly worse off. Or am I missing something?
Do you really need to take Calcutta? Is it not basically enough to put them down to 5 IPC/turn? With just one cheap submarine to convoy, that’s now 2-5/turn, with the odds heavily favoring closer to 2. The money islands give you the economy to fight America ASAP, and not sending pieces of your fleet so far west to India allows you to continually threaten ANZAC (so that it builds land units instead of navy) and to keep America the hell away.
Is the point of this more to allow Germany some breathing room before a US entry, and if so, how do you imagine that plays out? Or is taking Calcutta and then pushing into the middle east from two Indian mICs churning out units the ultimate goal?
As it is now, it seems like you’re slowing Japan down by 1 turn with little, nothing, or worse, to show for it. And if the 18+2 Ruskies stack Amur and you must go up there and kill them, this strategy doesn’t apply.
