@Alsch91:
Does doing 3 prevent you from doing 1 or 2?
Not really. You could do 1&3 or 1&2, I suppose.
The real problem is that Kill England First is reactive, you have to see what the Allies do on Round 1 and make a determination at the start of Italy 1. Does America do something silly like move to SZ 16? Then you know the jig is up, dont buy the bases, dont declare war, move back and focus on China. Does England move for Gibraltar and ignore the Italian fleet? The jig is up, run and push on Russia instead!
You cannot test a theory if your opponent knows what you are testing. Jim and Jimmy found a way to stop Sea Lion in Alpha 2, it was at the expense of everything else and assumed that Germany had to buy 10 transports on round 2, but they could do it. Same for Alpha 3. America can stop Kill India first by giving up it’s fleet and it’s position on the board. America can stop Germany from recovering after Sea Lion, if they know it is coming, by moving their warships out of the Pacific. (Granted in the one case this was tried, they lost anyway and Japan won, but they met their mission objective - which was to allow Russia free reign in Europe.) Sorry, but it cannot be done. You cannot test a theory on someone that knows you are testing a theory - especially if they know what the theory is.
I am certain, given an unsuspecting opponent, that the Kill England First strategy will win at least 90% of the time.
