I don’t think the KIF strategy is what everyone makes it out to be. Maybe you guys are playing against opponents who like to concede early or something. :-D
For the endgame, you can’t just trade Moscow for Rome, in the same way that you can trade Moscow for Berlin. Plus Italy does not have a very large purse to capture, so it could be that you waste all your money and time trying to Kill Italy, and succeed, only to find the Japs in Moscow. Which turns the whole thing on its head again 2v2.
I guess if you’re the kind of player who always calls the game when a capital falls, the KIF thing would work. But the real reason why KGF was more attractive than KJF in revised, was because of the endgame dynamic. For the Allies, Germans in Moscow/USA in Tokyo was a deadlier proposition than Japs in Moscow/USA in Berlin, so they’d go KGF to ensure the endgame advantage. I think the Italy thing is going to have to be evaluated the same way (eg. can you afford to send everything into the Med, and still secure Moscow from the remaining Axis players? Is it worth it?.)
Just food for thought :)
