@uffishbongo:
There are two kinds of KJF’s in the world: those that start that way, and those that switch to it. I was referring to the first. If you decide at the beginning of the game “hey, I want to go KJF this game,” then it’s very, very difficult to make it work unless you go all in. This means things like stacking Buryatia with 6 inf on R1, moving 2 inf into Sinkiang, and basing fighters in Kazakh to up the threat to Manchuria; building an India complex UK1; consolidating UK fleet in SZ 30, or taking Borneo, on UK 1; and either building a Sinkiang IC and spending the rest of America’s paycheck in the Pacific, or skipping Sin and going full bore on the boats. If you only do one or two of these, Japan can easily squash them, but with all together it can be too much for them to handle.
I should add the disclaimer that I’ve never successfully won a game this way, nor has anyone beaten me with this tactic. I know some players have been able to make it work, but it’s awfully difficult. You can contain Japan’s Asia expansion, but sinking their navy tends to take a while (unless they defend poorly), and Russia just can’t hold out long enough against a good German player without American assistance (and with only half-hearted UK assistance if they build the India factory).
Being that I won with KJF alot, I’ll comment.
My version does indeed start with USSR invading manchuria. adding troops in India, and massing the UK/USA fleet at Solomons.
It is difficult for the USA, by itself, to handle the Japanese fleet quickly enough. Which is why you move the UK fleet south, then towards NZ. The USA fleet moves to solomons USA2, followed by the UK fleet on UK3.
The additional sub, transports DD, and carrier (which can be filled with 1 or 2 USA fighters) allows for the defensive power to defend against a J3 attack. (even if it didnt, a screen works).
The dual fleets allow for faster taking of islands (and India protection).
The UK must still send troops towards Norway (along with USA) so what you are giving up (for the forseeable future) is Africa. After Borneo/DEI is taken, and India preserved, the UK can go to africa while the USA continues to punish Japan.
Is it exactly easy? No.
But it does work.
