@Hobbes:
Regarding the Allies building ICs, I just had one an unique situation on a game, playing as Axis.
R1 attacks WRus and nothing else and builds 6 art. G loses the battleship while killing the destroyer on SZ15 and fails to conquer Egypt but clears it of UK units. Then the UK builds 1 IC on Egypt and moves the Indian fleet to the Med but doesn’t attack the Japanese transport on SZ59.
With Japan I made 3 attacks: India, China and SZ52, all successful and transported 4 units to French Indochina. Then the US buys an IC as well and places it on Sinkiang (I would have placed it on Brazil actually). Then the US starts building a Pac fleet since Japan builds an IC on India and goes after Egypt. It could have been quite an interesting game actually, since an IC on Brazil would be able to support the Egypt one while the US would keep growing on the Pacific.
The problem? Germany. Russia build a lot of offensive units and moved a large stack on Ukraine on R2 but Germany crushed that stack on G2, winning the territory with 6 armor remaining. From that moment on Germany completely controlled the Russian front. It’s almost impossible to keep the Germans away while having to defend an IC on Sinkiang.
Hobbes, without questioning your brilliance I do think this game was too special to give a final verdict. Moreover this was not the India + Sink ICs strategy. And from what you say it seems evident Russia did play in a largely suboptimal way. But UK too was not played very well. What? Not sinking the second japanese trannie? Give me more of this in the games i play please…
Basically i would not write the double ICs strategy completely off, but for the UK India IC to be build the UK2 only. The reason is that I think the right time to decide whether to go agressively after Japan is right after J1. The agressive game might actually include under special circumstances given to positioning of Japaniese units the two ICs. Say Japan screwed Pearl, or what was left there appears to be an easy prey. Say India is kept by UK and FIC is weak. Say China did not go very well. Say Bur stack is intact. Why not to build sink IC, some ships off LA, a bmb with Russia, and an India IC. I would not like to face all of that if i am japanese player.
At the same time, in the games I played so far when I decided to go after Japan, Air and ships builds with US and an IC in SA with UK to contest Germans there and to support the US efforts in South Asia later in the game served me better.
The moves in my games basically created set-up where US was fighting Japan that was strugling heavy to get the same income as US which kept sinkinag and stood on 40. When it was not possible for Japs to keep the pace in the arms race in PAcific and lost the first island, she was practicaly finished as a potential threat to Russia.
Meanwhile Russia did trade UKR, BEL and KAR as usually and UK was slowly step by step building its fleet to put pressure on Germans just to remind them russia is not the only thing they have to think about. I would build an IC in SA UK3 the latest if the situation in Africa required it, but rather R2 if the Germans retook AE G2 and I saw I cannot counter.
Sinking the med fleet and getting the upper hand with UK in Africa i did see as the major Strategic priority to keep UK as the power capable of supporting Russians in their fight with Germans effectively. If you keep Russia 20+ and UK 20+ in the critical stage among R3-6 and you do not let Germany exceed 40 too much you should be ok I guess. Because when US contains Japan, and starts to divert most of the resources against Germany, no one can stand it for too long.
