Try using tanks first to exploit this weakness of the IPM as the Allies then move on to planes b/c doing it with planes takes a great deal of skill and game knowledge and there is not a great deal of margin of error in terms of purchasing. If you buy too many planes too quickly you can get in trouble and if you buy a few over a very long period this unique ploy might be made irrelevent. With tanks you have more options and its easier for a lower skilled player to enact it adequately. If you are worried about losing Africa dont. If the Brits slide their tanks into Cauc they can shield SEuro from the Japanese and delay a full takeover by them. Also when the Japs move a large fleet into FICSz to threaten Africa you can take Turkey with the armor in order to threaten a retake. In essence you defend Africa with but a few guys, I go as small as 2-3 or even 1. Japan is too weak to afford a press on Russia and a lurch for Africa and if Britain can reatake it immediately then it does no good. Of course British steel in Cauc and still hit EEuro and Novo, but if the Japs have gone “all in” to FICSz then you know they have to “crap or get off the pot” meaning they either have to go back to Japan on the next turn or go to Africa. If they go to Africa you make sure you have enough tanks to overwhelm(Japan shouldn’t be able to go with much more than 16inf so 3inf 20arm some air should be able to take with ~17arm, enough to withstand most counterattacks. That is unless Japan backs off troops f/Sink to India for just this, but in that situation Japan is costing them not 1 but 2 turns of reinforcements to Siberia so Russia should be able to push Japan back quite a ways there and the British steel can help.
