Clayton, I have tried that as well. It only work if the Germans really cooperate in the atlantic. But it is seriously based on luck and that is not the way I like to play the game. If you do it right you are forcing the allies to heavily invest into their navy, that means more than just the AC the UK buys normally.
The point of that strat is to let Germany hold Africa longer than it should control it, while slowly but steady advancing to Moscow with the Japs. Buying time for Germany by stalling the allies with their shuck shuck. I must say that I am like 4-1 playing this, but I played against some guys who were not really experienced so I don’t really put much value to it. The only thing that really helps this strat is that your opponent is totally offguard if you do this move, so you have some element of surprise. The last thing I recommend doing if you play this strat, is combine Germany and Japan! If you don’t you will lose really hard, because you lose your fleet, won’t advance against Russia and won’t hold Africa… I usually bought a bomber on Ger 1 to get started this strat. (a 23 bid we always play)
